Reschedulling in ATP
Hi SAP Gurus,
Problem is when production wants to carry out assembly process, they do not have sufficient component in stock.
What user noticed is daily MRP job runs V_V2 to re-allocated stock (including components), even the stock meant for production.
The component Sale Order under customer A still gets the confirmed qty earlier than the Production sale order under customer B
Please let me know the reason why the component sale order has higher priority than the production order.
Please suggest me wheather i need to have a delivery priority ( high) in production order @ item level inorder to achieve this , or need to maintain delivery priority at CMR level?
Please advice
Guna
Hello Guna,
Please click on Info icon on transaction V_V2.
The items and schedule lines found in the selection are sorted according to 'Priorities' - document category, delivery priority, creation date of the item or schedule line (for stock transfer purchase orders and delivery plans) entered on the selection screen or according to the schedule line date of the earliest schedule line with order quantity, document number and item number and then transferred to the availability check. Priority 1 is highest priority and priority 5 the lowest.
This is how they are prioritised. As for stock, it will be taken into consideration if it is set for checking rule. If you do not want that stock you can change the settings of the checking rule.
Thanks
Amber

How to configure ATP check for "create standard order in SD (OR type)"
first, I had check my stock, I only have ten PC
, but when I enter 100 PC in a OR order, and issue ATP check, it is carries out, why? I had set availavility check into 02 in MRP3 viewAvailability check
1. Availability check is an integral part of the business process that determines if the required delivery quantity can be met on a required delivery date. For this purpose the system takes into account pre-delivery activities such as scheduling for picking or packing times and the time taken to produce or obtain the material. It also performs several background functions such as Backorder processing, rescheduling and ATP quantities.
2. Backorder processing: processing of a sales order that has not been fully confirmed or not confirmed at a certain delivery date.
3. Rescheduling: is a proposal of how u2013 confirmed quantities already assigned to a sales order can be reassigned to other sales orders that have a higher priority.
4. Available to promise (ATP): is a process of checking the available quantities of a material. The ATP quantity consists of warehouse stock + planned receipts (incoming stock) u2013 planned issues (outgoing stock). to examine stock on hand (CO09) proceed to logistics u2013 sales & distribution u2013 sales u2013 environment u2013 availability overview.
5. Replenishment lead time (RLT): is the time taken for the material to become available either internally (in house production) or externally (from a vendor). The most important things to consider during an external procurement are purchasing and MRP2 (procurement) views of MMR where the processing time for purchasing, planned delivery time and goods receipt processing time are taken into account. On the other hand internal procurement is based on in house production time (MRP 2 view) goods receipt processing time or alternatively RLT time, which is found on MRP 3 view.
6. RLT (Replenishment Lead Time) is the time taken for the material to become available. RLT is only used when doing an ATP check (Available To Promise). The value of RLT for a material is specified on material master record.
7. There are three types of availability checks u2013
Check on basis of ATP quantities.
Check against product allocation.
Check against planning.
Configuring Availability check through Checking Groups
1. The checking group + checking rule determine how the availability check is to be performed.
2. The checking group determines whether and how the system checks the stock availability and generates requirements for material planning. The checking group defines what type of requirements will be passed on i.e. summarized requirements (daily/weekly) or individual requirements for each sales order.
3. The checking rule applies to how the availability check is to be carried out at the transaction level. Note that you must define checking rules for each individual application such as for production orders for example. In Sales and Distribution, the checking rule is specified internally within the system and cannot be changed.
4. The checking rule, in conjunction with the checking group, determines the scope of the availability check for every business operation; that is, which stocks, receipts and issues are to be included in the availability check and whether the check is to be carried out with or without the replenishment lead time.
5. Briefly explaining the above u2013 checking group determines which type of requirement to be passed on to MRP whether it be individual or summarized and checking rule which is at the transaction level and can be configured independently for each application module, determines which stocks, receipts and issues to be taken into account. For performing an availability check checking group has to work in conjunction with checking rule.
6. Advantages of individual processing over summarized processing u2013
Backorder processing is possible.
You can access (MD04) order, line and schedule line individually which gives a greater control on available stock and requirements placed on stock.
The system automatically uses individual requirements in case of special stock items.
7. Required data for the Availability check to be carried out u2013
The Availability check must be switched on at the requirement class level.
The Availability check must be set at the schedule line level.
A requirements type must exist by which the requirements class can be found.
A plant must be defined in the sales order for each schedule line item (in other words plant must be defined for every material in MMR).
A checking group must be defined in the material master record in the MRP3 screen in the availability check field.
8. Configuring Availability check and defining Checking Groups u2013
Checking groups are introduced into the sales order based on the setting in the material master record.
SAP standard checking groups are 01 u2013 summarized requirements and 02 u2013 individual requirements or you can create your own by copying the standard ones.
Total sales and total deliveries columns are there to configure a checking rule to sum up requirements to post to MRP either individually or by day or week.
Block quantity required can be set if you want several users to be able to process the material simultaneously in different transactions without blocking each other.
The no check indicator is CHECKED when you DO NOT want the system to carry out ATP check.
9. Defining material block for other users u2013 the block check box is an indicator that enables you to block material master records of a particular material during the availability check and restrict other users from accessing same master record and reserve the material. If the block is not set, two users can confirm the same material at the same time for two different orders, not knowing if the stock is available or not. If you select this field, the material is blocked during the availability check and other users cannot: a) Make changes in the material master record. b) Create purchase orders for the material. C) Create orders for the material.
10. Defining default values for checking groups - Checking groups are introduced into the sales order based on the setting in the material master record.
However if there is no entry present in the material master record for the checking group, a default value can be set here, depending on material type and plant.
This default value will be used by the system depending on the material type mentioned in MMR and plant in sales order.
If an entry exists, this default value is over written by MMR.
11. Controlling Availability Check u2013 in this section, you tell the system what stock on hand and what inward and outward movements of stock it must take into account when performing the availability check in addition to whether or not to consider the replenishment lead time.
12. These settings are based on the checking group that is assigned to the material master record and the checking rule that is predefined and assigned to the sales and distribution transaction.
13. These settings carry out control both for sales order and delivery as well. This is due to the fact that you may want to include specific stock or incoming stock for the sales order, yet at the time of the delivery only include physical stock on hand waiting to be shipped.
14. It is possible to indicate to the system that you would like the availability check NOT TO CHECK the stock at the storage location level. This indicator is used to set the scope of the availability check.
15. It is used to switch off the check at storage location level. You create a reservation for a particular storage location. However, the scope of the availability check is set in such a way as to exclude the storage location. In this case, the system carries out the check at plant level only and does not take the storage location into account that is specified in the reservation.
16. Should you not want the system to automatically check RLT, you may indicate so here. RLT is the time taken for a material to become available. It is only used when doing an ATP check and is taken from MMR.
17. defining the elements in the availability check entirely depends on the business needs, but a few tips are given under u2013
When controlling the Availability check at the time of the sales order, a purchase requisition does not necessarily indicate by it is going to come into the plant.
A shipping notification on the other hand - a confirmed purchase order u2013 is a good indicator of receiving stock on a specified date.
It is always recommended not to select the shipping notifications for the delivery requirements type as you may not actually receive the stock into plant or warehouse for which you are creating a delivery. -
Avoid Sales Order rescheduling
Hi Gurus,
please do you know a way to exclude sales orders / sales order items from rescheduling run (V_V2)?
The only way I know is to set the flag "Fixed Quantity/Date" at item level. Do you know any other way please?
Thank you very much
Kind Regards
AndreaThere is a way:
In the calling program, export a parameter to the memory.
Import the parameter is in Customer-Exit EXIT_SAPLATPC_001.
Transaction.. SMOD
Enhancement.. ATP00001
Component.... EXIT_SAPLATPC_001,
Include...... ZXATPU01.
The customer exit is used in function AVAILABILITY_CHECK_CONTROLLER, just before calling function 'AVAILABILITY_CHECK'.
Simply refreshing the ATP tables in the customer-exit, will prevent the ATP check from being executed (because we removed the list containing the materials for which the ATP check needs to be done). As a result, the function 'AVAILABILITY_CHECK' will not be processed.
EDIT: Hmmm, I was too quick here. This is only valid for ATP relevant items. If it is only rescheduling, you'll have to make changes to the logic of the V_V2 program. Sorry, I was just too busy with the ATP check lately so when I saw this question I jumped from Rescheduling to ATP too soon!

Hi All,
What is Part number. When I print GR/GI slip, its appearing. From where systems picking this Part number.

Inventory-Managed Manufacturer Part Number
Purpose
Manufacturers can identify their parts uniquely and regulate the use of interchangeable parts in their parts catalogs. Inventory-Managed Manufacturer Part Number (IM-MPN) belongs to the component Manufacturer Part Number (IS-AD-MPN) and includes the following features:
· Identification of parts using the manufacturer part number (MPN) issued by the manufacturer
The system finds, identifies, and displays these parts using the unique combination of manufacturer-specific details ‑ the Manufacturer Part Number (MPN) and the External Manufacturer. These parts are inventory-managed manufacturer parts, and are maintained with a complete material master record and their own stock.
· Management of part interchangeability
The system recognizes parts from different manufacturers that have the same technical properties and are interchangeable in Purchasing, Inventory Management, MRP, and the Availability Check, as being interchangeable; these parts have their own stock. The management of part interchangeability includes:
¡ Inventory-managed manufacturer parts that are fully interchangeable with each other are grouped in a common class of interchangeable parts - a form-fit-function class (FFF class).
¡ You can group fully interchangeable parts of an FFF class in MPN-MRP sets subject to plant and planning area. The system treats these parts are treated as fully interchangeable parts in planning, inventory management, and the availability check.
¡ Restricted or one-way interchangeable parts cannot belong to the same FFF class. You use interchangeability codes to group these parts. Restricted interchangeability is available for all processes that support MPN. These processes are:
§ Sales order product selection
§ Sales rescheduling reports
§ ATP check for components in PM/CS order
§ General availability check
§ Goods receipt in transaction code MIGO
§ Stock overview
§ Stock transport order
§ Configuration control
Integration
The functions for Inventory-Managed Manufacturer Part Number are fully integrated with the components for Purchasing, Material Requirements Planning, and Sales and Distribution.
These functions supplement the functions for the non-inventory-managed manufacturer part number (MPN), which are available in the standard system as of Release 4.0. These functions contain a special material type (HERS), and an Approved Manufacturersu2019 Part List (AMPL). You can define different manufacturer parts as interchangeable by grouping their material masters in an internal material master.
Catalog Content Management (CCM) 1.0 supports the use of concatenated manufacturer part numbers.
Features
The functions include:
· Master Data Maintenance
Maintenance and display of full and restricted interchangeability, as well as maintenance of MPN-MRP sets.
· Input and Output Conversion of Material Numbers
The input conversion of material numbers allows you to enter the MPN and the external manufacturer instead of the SAP material number.
The output conversion ensures that the system outputs the MPN and external manufacturer in lists and on the screen instead of the SAP material number.
· Interchangeable Manufacturer Parts in Purchasing
When processing quotations and purchase orders, you may have to exchange the part in the current process with another part, because you have received a quotation, notification, or delivery for an alternative part. The system supports you in changing and allocating the relevant order items so that the follow-on steps (in particular, goods receipt and invoice verification) refer to the part that was actually delivered.
· Interchangeable Manufacturer Parts in MRP
There is a risk that inventory management on the MPN level could cause an excess of stock if the system does not take account of the interchangeability of parts. Therefore, in material requirements planning, the system takes account of the interchangeability of the parts to be procured, and ensures that a part is not ordered if another fully interchangeable part is in stock.
· Interchangeable Manufacturer Parts in Inventory Management
The system holds different manufacturer parts in stock as separate parts. This gives you an overview of the manufacturer parts that are actually available, and allows the system to manage additional information, such as serial numbers or valuation. Cumulative analysis of interchangeable parts is also possible.
· Interchangeable Manufacturer Parts in the Availability Check
If a part is not available, the availability check in PM orders and production orders also takes account of interchangeable parts.
· Creation of subitems in stock transport orders. For more information, see Interchangeable Manufacturer Parts in the Availability Check and Interchangeability in Stock Transport Orders.
· Goods movement using transaction code MIGO. You can interchange parts in the following:
¡ Goods issue for the stock transport order
¡ Goods receipt for the purchase order
Goods issue for the reservation
Hope it is usefull for you .
Thanks

Availability check for Make to stock and Make to Order
Dear All,
Client is selling Make to stock and make to Order material.
How and what settings need to do for Avaialbility check.or we can use standard one.
I hope in case of Make to Order availability check may not happen.
Please correct me.

Set Availability Check to Exclude Planned Order
Hi All,
anyone know how to set the availability check so it will not include the planned order in the calculation ?
I find one setting in SPRO, the path is :
Sales & distribution ==> Basic functions ==> availability check and Transfer of Requirements ==> Availability Check ==> Availability Check with ATP Logic or Against Planning ==> Carry Out Control for Availability Check
select one of the record, and update filed "Incl. Planned Orders".
I've uncheck that field, but I can't get the appropriate result. When I create a new sales order, the availability check still take the planned order I created before into account.
The problem is, my user want to prevent creating delivery before the goods are already put in the stock. So the planned order should not be considered in the availblity check.
Thank you in advance
RudyHi Rudy,
Concept of availability check is to verify if the stock is available at the time of creation of sales order. If available, when it can be ready for delivery (as Packing, arranging for transportation, etc may have lead time) & if not available, when it would be available considering Packing, arranging for transportation, etc lead time.
Availability check whether material is available on required delivery date (backward scheduling) or not. If not available on required delivery date, system will propose next available date (forward scheduling)

Sales order Availability check for Reservation
hi ,
When i create a sales order , it should check the availability also reserve the required quantity for the order
automatically. pls let me know the step by step process
mohanHello,
Availability check with ATP logic can only promise the amount of stock that can be delivered to the customer on a particular date, it cannot reserve the stock until the order the saved. But once you save the order the stock allocation is done automatically.
Availability check is an integral part of the business process that determines if the required delivery quantity can be met on a required delivery date.
For this purpose the system takes into account pre-delivery activities such as scheduling for picking or packing times and the time taken to produce or obtain the material.
It also performs several background functions such as Backorder processing, rescheduling and ATP quantities.
The system will not allocate or reserve any stock of items until the order is saved.

Availability Check configuration
Hi All,
I want to configure availabiliy check but I am a bit confused with the config part. Soneone plz explain the config process.
Also tell me what is the exact link ( in config ) by which the availabilty check gets triggered.
Regards,
Danny.Dear Danny,
Hope the material pasted here helps you... :
Availability Check & Transfer of Requirements
Availability check
1. Availability check is an integral part of the business process that determines if the required delivery quantity can be met on a required delivery date. For this purpose the system takes into account pre-delivery activities such as scheduling for picking or packing times and the time taken to produce or obtain the material. It also performs several background functions such as Backorder processing, rescheduling and ATP quantities.
2. Backorder processing: processing of a sales order that has not been fully confirmed or not confirmed at a certain delivery date.
3. Rescheduling: is a proposal of how u2013 confirmed quantities already assigned to a sales order can be reassigned to other sales orders that have a higher priority.
4. Available to promise (ATP): is a process of checking the available quantities of a material. The ATP quantity consists of warehouse stock + planned receipts (incoming stock) u2013 planned issues (outgoing stock). To examine stock on hand (T-Code - CO09) proceed to logistics u2013 sales & distribution u2013 sales u2013 environment u2013 availability overview.
5. Replenishment lead time (RLT): is the time taken for the material to become available either internally (in house production) or externally (from a vendor). The most important things to consider during an external procurement are purchasing and MRP 2 (procurement) views of MMR where the processing time for purchasing, planned delivery time and goods receipt processing time are taken into account. On the other hand internal procurement is based on in house production time (MRP 2 view) goods receipt processing time or alternatively RLT time, which is found on MRP 3 view.
6. RLT (Replenishment Lead Time) is the time taken for the material to become available. RLT is only used when doing an ATP check (Available To Promise). The value of RLT for a material is specified on material master record.
7. There are three types of availability checks u2013
Check on basis of ATP quantities.
Check against product allocation.
Check against planning.
Configuring Availability check through Checking Groups u2013
1. The checking group + checking rule determine how the availability check is to be performed.
2. The checking group determines whether and how the system checks the stock availability and generates requirements for material planning. The checking group defines what type of requirements will be passed on i.e. summarized requirements (daily/weekly) or individual requirements for each sales order.
3. The checking rule applies to how the availability check is to be carried out at the transaction level. Note that you must define checking rules for each individual application such as for production orders for example. In Sales and Distribution, the checking rule is specified internally within the system and cannot be changed.
4. The checking rule, in conjunction with the checking group, determines the scope of the availability check for every business operation; that is, which stocks, receipts and issues are to be included in the availability check and whether the check is to be carried out with or without the replenishment lead time.
5. Briefly explaining the above u2013 checking group determines which type of requirement to be passed on to MRP whether it be individual or summarized and checking rule which is at the transaction level and can be configured independently for each application module, determines which stocks, receipts and issues to be taken into account. For performing an availability check checking group has to work in conjunction with checking rule.
6. Advantages of individual processing over summarized processing u2013
Backorder processing is possible.
You can access (MD04) order, line and schedule line individually which gives a greater control on available stock and requirements placed on stock.
The system automatically uses individual requirements in case of special stock items.
7. Required data for the Availability check to be carried out u2013
The Availability check must be switched on at the requirement class level.
The Availability check must be set at the schedule line level.
A requirements type must exist by which the requirements class can be found.
A plant must be defined in the sales order for each schedule line item (in other words plant must be defined for every material in MMR).
A checking group must be defined in the material master record in the MRP3 screen in the availability check field.
8. Configuring Availability check and defining Checking Groups u2013
Checking groups are introduced into the sales order based on the setting in the material master record.
SAP standard checking groups are 01 u2013 summarized requirements and 02 u2013 individual requirements or you can create your own by copying the standard ones.
Total sales and total deliveries columns are there to configure a checking rule to sum up requirements to post to MRP either individually or by day or week.
Block quantity required can be set if you want several users to be able to process the material simultaneously in different transactions without blocking each other.
The no check indicator is CHECKED when you DO NOT want the system to carry out ATP check.
9. Defining material block for other users u2013 the block check box is an indicator that enables you to block material master records of a particular material during the availability check and restrict other users from accessing same master record and reserve the material. If the block is not set, two users can confirm the same material at the same time for two different orders, not knowing if the stock is available or not. If you select this field, the material is blocked during the availability check and other users cannot: a) Make changes in the material master record. b) Create purchase orders for the material. C) Create orders for the material.
10. Defining default values for checking groups - Checking groups are introduced into the sales order based on the setting in the material master record.
However if there is no entry present in the material master record for the checking group, a default value can be set here, depending on material type and plant.
This default value will be used by the system depending on the material type mentioned in MMR and plant in sales order.
If an entry exists, this default value is over written by MMR.
11. Controlling Availability Check u2013 in this section, you tell the system what stock on hand and what inward and outward movements of stock it must take into account when performing the availability check in addition to whether or not to consider the replenishment lead time.
12. These settings are based on the checking group that is assigned to the material master record and the checking rule that is predefined and assigned to the sales and distribution transaction.
13. These settings carry out control both for sales order and delivery as well. This is due to the fact that you may want to include specific stock or incoming stock for the sales order, yet at the time of the delivery only include physical stock on hand waiting to be shipped.
14. It is possible to indicate to the system that you would like the availability check NOT TO CHECK the stock at the storage location level. This indicator is used to set the scope of the availability check.
15. It is used to switch off the check at storage location level. You create a reservation for a particular storage location. However, the scope of the availability check is set in such a way as to exclude the storage location. In this case, the system carries out the check at plant level only and does not take the storage location into account that is specified in the reservation.
16. Should you not want the system to automatically check RLT, you may indicate so here. RLT is the time taken for a material to become available. It is only used when doing an ATP check and is taken from MMR.
17. Defining the elements in the availability check entirely depends on the business needs, but a few tips are given under u2013
When controlling the Availability check at the time of the sales order, a purchase requisition does not necessarily indicate by it is going to come into the plant.
A shipping notification on the other hand - a confirmed purchase order u2013 is a good indicator of receiving stock on a specified date.
It is always recommended not to select the shipping notifications for the delivery requirements type as you may not actually receive the stock into plant or warehouse for which you are creating a delivery.
ATP
Types of Availability Check in Sales and Distribution
Processing
There are three types of availability check:
_ Check on the basis of the ATP quantities
_ Check against product allocation
_ Check against planning
The following SD-specific control features need to be maintained in Customizing:
_ Checking group
The checking group controls whether the system is to create individual or collective
requirements in sales and shipping processing. In addition, a material block for the
availability check with transfer of requirements can be set here. The checking group can also be used to deactivate the availability check. This option was created especially for the assembly order so that when the bill of material is exploded in the assembly order, the individual components, if necessary, can be classified as non-critical parts as far as procurement is concerned.
The checking group specifies in combination with the checking rule the scope of the availability check. It is proposed in the material master record on the basis of the material type and the plant, and copied into the sales and distribution documents. _ Checking Rule
You use the checking rule to control the scope of the availability check for each
transaction in sales and distribution. You also specify whether the check should be
carried out including or excluding replenishment lead time. The individual checking rules define by transaction, which stock and inward and outward movement of goods should be taken into account for the availability check. _ Schedule line category
You can control with the schedule line category whether an availability check and
transfer of requirements should be carried out in the sales documents. The possible settings for this at schedule line level are dependent on the settings in the requirements class which is determined from the requirements type of the material. _ Delivery item category
The delivery item category can be used to control whether an availability check takes place in deliveries. Requirements type
The various requirements are identified by their requirements type. The requirements type refers to the requirements class and its control features.
_ Requirements Class
The requirements class contains all control features for planning such as relevance for planning, requirements planning strategy and requirements consumption strategy. In addition, it is specified at a global level whether an availability check is to take place for the material in the sales and distribution documents on the basis of the ATP quantity (ATP = available to promise) and whether requirements are to be passed on. A finer degree of control can be obtained for sales documents using the schedule line category.
Replenishment lead time is only included in the check performed on the basis of the ATP quantity.
Prerequisites
An availability check can only be carried out if the following prerequisites have been fulfilled:
_ The control elements described above for the availability check must be maintained in Customizing for Sales and the relevant assignments made to the sales transactions
_ The availability check must be switched on at requirements class level and - for the availability check in the sales documents - at schedule line category level
A requirements type must exist by which the requirements class can be found
_ A plant must be defined. It can either be proposed from the customer or material master record or can be entered manually in the document.
_ A checking group must be defined in the material master record on the Sales/plant data screen in the Availability check field
Configuring entries of the Availability Check
IMG > SD > Basic fncs > Availability check and TOR > Availability check with ATP logic or against planningAvailability check > Define checking groups
You can use SAP std checking groups of 01 for summarized reqts or 02 for daily reqts or u can create ur own.
The columns total sales and total deliveries are selection options whereby u can configure a checking rule to sum up reqts to post to MRP either individually or by day or week.
Column 5, Block qty; set this block if u want several users to be able to process the material simultaneously in different transactions without blocking each other. The No Check indicator is used when u want a material to not be relevant for an ATP check.
Defining a material block for other users. The Block checkbox is an indicator that enables u to block the particular material from being checked for availability if it is already being checked at the same time by another user.
Defining the default value for checking groups. However should no entry exist for the checking group in the material master record, one can set a default value per material type and plant.
Controlling the availability check. In this section, u tell the system what stock on hand and what inward and outward movements of stock it must take into account when performing the availability check. These settings are based on the checking group that is assigned to the material master record and the checking rule that is predefined and assigned to the sd transaction. The carry out control for the availability check must be maintained for both the sales order and delivery.
TOR
IMG > SD > Basic fncs > Availability check and TOR > TOR
A line item in the sales order creates a schedule line. The schedule lines in the sales order transfer the requirements through to MRP. You can select the docs on which you want the TOR to happen. For ex, not for quotations.
The TOR aims to ensure the ordered materials are available for the requested delivery date. The TOR can be set for individual or for collective requirements (materials sales/plant view).master
The TOR is dependent on the following data:
The reqts type, reqts class, checking group and schedule line category.
The reqts type and class are determined in the strategy group MRP3)(material master
For TOR to be carried out, a few criteria need to be met:
Plant assigned to line item level, schedule line category should be switched on at TOR, TOR must be switched on at the reqts class level, checking group must be defined and allocated to the material master record (sales/plant view in the availability check field)
The reqts class is the controlling factor for the availability check and the TOR for all sd types.
Configuring the TOR:
1) Use std 041 reqts class or copy and rename it. Use the indicators to select if this reqts class must carry out an availability check and/or a TOR.
2) Define the reqts types. A reqts type is allocated to a single reqts class and not vice versa. It is based on the item category and the MRP type of the material.
3) Assign the rqts type to the relevant item category in the sales order and the MRP type found on the material master record.
You can select an alternative search strategy where u assign the reqts type to item category and MRP type. Can select source as 0, 1 or 2. (1 = Item type and MRP type strategy).
4) The TOR and Availability check can be selected/de-selected at the schedule line category level.
5) Block qty confirmation in delivery blocks. This is used to block the reservation of the TOR from MRP.
6) Maintain requirements for TOR. Requirements can be used to determine that the TOR to MRP is not carried out unless a number of conditions are met.
Availability Overview = CO09 > order qty, sd doc no, item no, requirements class.
sd no or dly no, lineStock requirements list = MD04 item, schedule line placing the demand
Stock overview = MMBE > total stock per company, then plant followed by storage location, and finally a breakdown per batch.
Transfer of requirments:
for TOR to happen the folowing control elements must be defined
1. requirmrent type.
2.requirement class.
3.checking group
4.schedule line category.
apart from the above the TOR must be switched on at
1.reqt class level.
2.schedule line level
3.checking group level.
4.plant must defined at the document item level
once order is raised the requirments are transfered from order to MRP by TOR,
various reqts are identified thru reqt type, reqt type are identified in the system thru
1. strategy group--MRP1 --mmr
2.MRP group.
3.material type.
4. ITEM category +mrp type
5.item category
once reqt type is identified it points to reqt class.
reqt class contains all the control factors suchas planing strategy,consumption strategy etc
basing on the item category group+ mrp type-- schedule line categories are identified.
if it is relevant for availability check, then the system does ATP CHECK(warehousestockplanned ordersproduction ordersconfirmed receiptsconfirmed goods issues) and decides whether goods are availabile on
the requested delivered date of the customer, if not system does a backward scheduling and confirms when material is available (materual availability date),
so if material is not available then system proposes 2 dates
1.customer delivery date
2.material availability date.
for availability check to happen the following pre-requistes must be there:
1.availability check must be swithched on at the requirment class level
2.schedule line level itmust be switched on
3.reqt type must be defined
4.checking group must be defined.
5.plant must be defined
6. the system takes by default checking group if not defined as material type and plant.
from SD the following componenets are importants
1.checking group:defines whether indivual orcollective req are to be passed
2.checking rule: defines scop of the check(what type of stock+with or without RLT)
3.schedule line category: this fine tunes whether availability check should be carried on at the sales document level or not.
4. delivery item category.
for config:
SPROSALES&DIST-BASIC FUNCTIONS--TOR&AVAILABILITY CHECK.
In material master the below mentioned must be defined also
1.strategy group.
2.scheduling margin key.
3.in house production time.
4. RLT time.
5.MRP group
Hope this above helps...
Give points if userful...
Thanks,

Hi sd gurus,
can anyone plz send me screen shots for availabilty check and tor in sd point of view ,plz help me am having the theory part idea but am not geting complete picture plz send meHello Srinu,
I cant provide you any screen shots for the topics you have asked. But pls go through the following notes. Its really good and you'll have a clear Picture on the topics.
Availability check is considered as a pre-sale activity, where as TOR and MRP are post sale activities.
Materials Requirements Planning (MRP) and Transfer of Requirements (TOR).
1. A schedule line in a sales order represents the customers intended delivery date and quantity to be delivered. In a standard sales order processing, the system transfers requirements (TOR) to Material Requirement Planning (MRP).
2. MRP - then determines if there is enough quantity of stock available for the scheduled delivery date. The TOR aims to ensure that the materials ordered are ready for the requested delivery date.
3. The TOR is closely integrated to Materials Management and Production Planning modules thus it must be configured in association with the respective teams.
4. The TOR can be set either for individual requirements or for collective requirements in MMR (Sales: general/plant and MRP3 views).
5. Individual requirements are the transference of requirement to MRP for each schedule line of the sales order. An advantage of this is that the availability overview (CO09 logistics material management environment stock availability overview) will show the order quantity, sales document number, item number and requirements class for each schedule line for which a demand has been created.
6. Collective requirements are a collective grouping of requirements created either daily or weekly that are transferred to MRP; but the documents processed in collective requirements cannot be individually identified from the availability overview (CO09). Collective requirements are useful to a business that deals with a large volume of sales orders per day, as it allows the business to have a clearer view of the availability overview and speeds up the response time within the system as well.
7. The system will automatically create individual requirements (irrespective of the collective requirements indicated in MMR) in case of special stock items such as consignment, returnable packaging, make to order stock etc.
8. The control elements that are used for Transfer of Requirements (TOR) and Availability Check are
the requirements class
the requirements type
the checking group
the schedule line category
9. The requirements class is the controlling factor for TOR and the availability check for all sales document types. It determines if the system has to perform TOR, Availability check and product allocation to any particular sales order.
10. The requirements class is determined from the requirements type of the material.
11. The checking group in general is the criterion that groups together all the checking rules from all application areas for a material. In conjunction with the checking rule, it defines the scope of the availability check for each business event; that is, which stocks, goods receipts and goods issues are taken into account in the availability check, and whether replenishment lead time is checked. The checking group must be defined and allocated to the material master record in the sales: general/plant view in the availability check field.
12. for TOR to be carried out, you need to ensure the following criteria are met
The TOR must be switched on at the requirements class level.
The schedule line category must be switched on for the TOR (fine tuning).
A plant must be assigned to the sales document line item level.
A checking group must be defined and allocated to the material master record in the sales: general/plant view in the availability check field.
Planning materials
It is possible to create a common planning material and assign similar materials to it (MRP 3).Independent requirements are created for the planning material to cover the requirements that are expected for the materials assigned to the planning material. This means that you do not have to create independent requirements for each material. Instead create a material and assign the same to the planning material already created with similar properties.
A valid material master record must exist for the planning material in the planning plant. The material master record of the planning material cannot contain a planning material as this procedure can only be carried out at single-level.
An appropriate strategy group must also be entered in the MRP 3 screen for planning with planning materials. The strategy group groups all the planning strategies that can be used for a particular material. The planning strategy represents the procedure used for planning a material and is (technically speaking) controlled by the MRP types.
Consumption mode defines whether and in which direction on the time axis from the requirements date (corresponds to the date when the sales order items were created) the consumption of customer requirements with planned independent requirements should occur. Consumption period must exit between 1 and 999 days.
Backward consumption only: starting from the requirements date, backward consumption is carried out within the relevant consumption period specified in MMR i.e. the system reduces the planned independent requirements that lie in the past. Likewise forward consumption only represents starting from the requirements date, the system reduces the independent requirements that lie in the future within the consumption period.
Backward/forward consumption: in this case backward consumption is performed first and forward consumption is performed later depending on the availability of the independent requirements in the past. Forward/backward consumption is vice-versa of the above.
Stock requirements list
1. Stock requirements list is the central table for planning and stock control. It is invaluable to the interpretation of the available stock and the situation of stock levels in a plant.
2. Menu path: MD04 logistics material management inventory management environment stock stock requirements list. Here you can see the order number or delivery number as well as the line item and schedule line placing the demand on the given plant. It also shows the required and available quantity of material per order.
3. Another view of the stock situation in plant can be obtained from MMBE (stock overview). This view will show you total stock per company code, then at the plant, storage location and at batch level.
4. A useful tool in MMBE is material movements, which can be viewed by selecting stock line and proceeding to environment, material movements.
<b>Configuring Transfer of Requirements </b>
1. IMG sales & distribution basic functions availability check & TOR transfer of requirements define requirements classes.
2. Requirements class (OVZG) is the controlling factor for the availability check and TOR for all sales documents. It determines whether the system should perform the transfer of requirements, availability check and product allocation when a sales order is created.
3. The system uses the entries used at this level as default and brings the data into the sales order. The same entries made at the schedule line category level (VOV6) are only used to fine tune the entries previously made at the requirements class level. The standard requirement class is 041 (order/delivery requirement).
4. Requirements type (OVZH) (displayed in the sales order beside schedule line category) requirements types identify the different requirements, such as sales order requirements, delivery requirements or individual customer requirements. The requirements types can be changed, for example, in order to represent customer-specific terms.
5. The first step in the process of configuring TOR is to define a requirements class (041 standard) by copying the standard one. It contains the preconditions for performing availability check, TOR and product allocation.
6. Next step is to create a requirements type, which is based on item category and MRP type of the material and allocate the previously defined requirements class to it. A requirements class can be allocated to more than one requirements type. It is possible to change the requirements type manually at the time of creating the sales order.
7. MRP type in the MMR determines how a material is planned for requirements i.e. automatic reorder point planning, manual reorder point planning or forecast based planning.
8. Determination of requirements types using transaction: when a sales order is created, the system looks for a relevant requirement type by using its own search strategy. Either it uses the following search strategy or you can make the system skip this entire process and straight away search for item category and MRP type by selecting 1 in the Q field while configuring determination of requirements types using transaction.
9. First attempt is to find the requirements type using strategy group in MMR.
10. If strategy group is not found, it will look for MRP group (MRP group groups together material with similar planning requirements and allocates special control parameters for planning such as strategy group, planning horizon and the creation indicator for planning run.
11. If MRP group is not found, it will try to access MRP type.
12. If no requirements type is found using MRP type, the system will use material type when accessing the corresponding tables.
13. Failing to find the requirements type even at this stage, it will try to get the requirements type using the item category and MRP type.
14. If this doesnt work either, then it will try to determine requirements type using only item category.
15. If the last attempt fails, the system determines the transaction is not relevant for availability check or transfer of requirements.
16. As discussed earlier TOR and availability check are fine tuned at the item category level. This is done at this stage i.e. define procedure for each schedule line category as a next step.
17. Block quantity confirmation in delivery blocks (linked to VD05 customer block): in the standard sales order processing, the system transfers the requirements to MRP, but in some cases you may need to block a transaction due to a bad result of the credit check.
18. When requirements are transferred to MRP, the confirmed quantity is also reserved for confirmed sales documents . If a transaction is blocked for delivery, the required stock will be blocked so it cannot be used elsewhere. To prevent this, you can block the transfer of requirements for a delivery block in this step.
19. You can set a limit on the number of days you would want the system to postpone this block on confirmation of requirements. This can be done by setting the number of days to the block in the Def. period column.
20. Maintain requirements for TOR: can be used to determine that the TOR to MRP is not carried out unless a number of conditions are met. For example in a standard sales order processing, a purchase order may need to be created in order to meet the demands of the customer. This purchase order is used to purchase new stock in order to meet the demand on MRP for particular customers sales order. Here you define requirements that must be met in order for the purchase order or assembly order to be created.
<b>Availability check</b>
1. Availability check is an integral part of the business process that determines if the required delivery quantity can be met on a required delivery date. For this purpose the system takes into account pre-delivery activities such as scheduling for picking or packing times and the time taken to produce or obtain the material. It also performs several background functions such as Backorder processing, rescheduling and ATP quantities.
2. Backorder processing: processing of a sales order that has not been fully confirmed or not confirmed at a certain delivery date.
3. Rescheduling: is a proposal of how confirmed quantities already assigned to a sales order can be reassigned to other sales orders that have a higher priority.
4. Available to promise (ATP): is a process of checking the available quantities of a material. The ATP quantity consists of warehouse stock + planned receipts (incoming stock) planned issues (outgoing stock). to examine stock on hand (CO09) proceed to logistics sales & distribution sales environment availability overview.
5. Replenishment lead time (RLT): is the time taken for the material to become available either internally (in house production) or externally (from a vendor). The most important things to consider during an external procurement are purchasing and MRP 2 (procurement) views of MMR where the processing time for purchasing, planned delivery time and goods receipt processing time are taken into account. On the other hand internal procurement is based on in house production time (MRP 2 view) goods receipt processing time or alternatively RLT time, which is found on MRP 3 view.
6. RLT (Replenishment Lead Time) is the time taken for the material to become available. RLT is only used when doing an ATP check (Available To Promise). The value of RLT for a material is specified on material master record.
7. there are three types of availability checks
Check on basis of ATP quantities.
Check against product allocation.
Check against planning.
Configuring Availability check through Checking Groups
1. The checking group + checking rule determine how the availability check is to be performed.
2. The checking group determines whether and how the system checks the stock availability and generates requirements for material planning. The checking group defines what type of requirements will be passed on i.e. summarized requirements (daily/weekly) or individual requirements for each sales order.
3. The checking rule applies to how the availability check is to be carried out at the transaction level. Note that you must define checking rules for each individual application such as for production orders for example. In Sales and Distribution, the checking rule is specified internally within the system and cannot be changed.
4. The checking rule, in conjunction with the checking group, determines the scope of the availability check for every business operation; that is, which stocks, receipts and issues are to be included in the availability check and whether the check is to be carried out with or without the replenishment lead time.
5. Briefly explaining the above checking group determines which type of requirement to be passed on to MRP whether it be individual or summarized and checking rule which is at the transaction level and can be configured independently for each application module, determines which stocks, receipts and issues to be taken into account. For performing an availability check checking group has to work in conjunction with checking rule.
6. advantages of individual processing over summarized processing
Backorder processing is possible.
You can access (MD04) order, line and schedule line individually which gives a greater control on available stock and requirements placed on stock.
The system automatically uses individual requirements in case of special stock items.
7. Required data for the Availability check to be carried out
The Availability check must be switched on at the requirement class level.
The Availability check must be set at the schedule line level.
A requirements type must exist by which the requirements class can be found.
A plant must be defined in the sales order for each schedule line item (in other words plant must be defined for every material in MMR).
A checking group must be defined in the material master record in the MRP3 screen in the availability check field.
8. configuring Availability check and defining Checking Groups
Checking groups are introduced into the sales order based on the setting in the material master record.
SAP standard checking groups are 01 summarized requirements and 02 individual requirements or you can create your own by copying the standard ones.
Total sales and total deliveries columns are there to configure a checking rule to sum up requirements to post to MRP either individually or by day or week.
Block quantity required can be set if you want several users to be able to process the material simultaneously in different transactions without blocking each other.
The no check indicator is CHECKED when you DO NOT want the system to carry out ATP check.
9. Defining material block for other users the block check box is an indicator that enables you to block material master records of a particular material during the availability check and restrict other users from accessing same master record and reserve the material. If the block is not set, two users can confirm the same material at the same time for two different orders, not knowing if the stock is available or not. If you select this field, the material is blocked during the availability check and other users cannot: a) Make changes in the material master record. b) Create purchase orders for the material. C) Create orders for the material.
10. Defining default values for checking groups - Checking groups are introduced into the sales order based on the setting in the material master record.
However if there is no entry present in the material master record for the checking group, a default value can be set here, depending on material type and plant.
This default value will be used by the system depending on the material type mentioned in MMR and plant in sales order.
If an entry exists, this default value is over written by MMR.
11. Controlling Availability Check in this section, you tell the system what stock on hand and what inward and outward movements of stock it must take into account when performing the availability check in addition to whether or not to consider the replenishment lead time.
12. These settings are based on the checking group that is assigned to the material master record and the checking rule that is predefined and assigned to the sales and distribution transaction.
13. These settings carry out control both for sales order and delivery as well. This is due to the fact that you may want to include specific stock or incoming stock for the sales order, yet at the time of the delivery only include physical stock on hand waiting to be shipped.
14. It is possible to indicate to the system that you would like the availability check NOT TO CHECK the stock at the storage location level. This indicator is used to set the scope of the availability check.
15. It is used to switch off the check at storage location level. You create a reservation for a particular storage location. However, the scope of the availability check is set in such a way as to exclude the storage location. In this case, the system carries out the check at plant level only and does not take the storage location into account that is specified in the reservation.
16. Should you not want the system to automatically check RLT, you may indicate so here. RLT is the time taken for a material to become available. It is only used when doing an ATP check and is taken from MMR.
17. defining the elements in the availability check entirely depends on the business needs, but a few tips are given under
When controlling the Availability check at the time of the sales order, a purchase requisition does not necessarily indicate by it is going to come into the plant.
A shipping notification on the other hand - a confirmed purchase order is a good indicator of receiving stock on a specified date.
It is always recommended not to select the shipping notifications for the delivery requirements type as you may not actually receive the stock into plant or warehouse for which you are creating a delivery.

Sai -
We are currently not able to manage schedule ship date proposed by ATP when our warehouse is closed. For example , we would like that ATP doesn't propose any schedule ship date for the first of May , which is a non working day in France. The constraint is that we don't want our purchase need by date to be impacted by the process.
I tried to closed one day in FR1 calendar and, after testing with order management, it appears that ATP didn't propose the closed day, so that's fine, but, our purchase order lead time was increased of 1 day and this is not what we expected.
Can you help us to find the right process.
ThanksHi Sandeep,
when we try to Rescheduled out the PO and the request is errored out the with the error:-

ATP check with RLT - rescheduling keeps pushing confirmed date out???
In order entry, our availability check is looking only at inventory and RLT... so that if stock is unavailable, the line item gets confirmed for a future date based on the material's RLT. We have noticed, however, that every night when backorder rescheduling runs, the confirmed date is pushed out one day later (assuming that no inventory exists still). So it appears that BO rescheduling is recalulating the confirmed date based on the current date + RLT.
Does this make sense? Is there any way we can make the original confirmed date stick? We don't want to use the Fixed Date & Qty flag on the schedule line screen, because we want to be able to pull the confirmation (and delivery) in earlier if the inventory is available earlier... we just don't want it to keep getting pushed later.This boils down to a business question.
Say you have a material with a 30 day RLT.
On Day 1, an order is placed - and due to no stock or planned receipt of stock with the 30 days - the delivery date is moved out 30 days based on the RLT.
Now it's day 29, you run the backorder report and there is still insufficient stock / replensihment plan within the next 30 days.
==> Do you want to keep the promised delivery date of day 30 - or is day 59 more realistic?
More to the point, why hasn't stock been acquired or a replenishment plan / order been created in the previos 29 days?
The RLT shouldbe set so that there is a very high likelyhood that the order can be fulfullled ini that time line.
To me, it makes sense to keep pushing out the date. When stock actually shows up in sufficient quantity, the date will be moved back up. -
Rescheduling of Unconfirmed Sales Orders
Dear All,
I was trying to reschedule the sales orders whose schedule lines are not confirmed using a report SDV03V02 (V_V2) but that picks up the confirmed open sales orders also in the process of rescheduling.
My issue is I wanted set some indicator where it can pick only unconfirmed sales orders and not all the open sales orders.
This program is been run in Background daily once so I can not put any specific material number also.
Please let me know if there is any alternative method to reschedule only unconfirmed sales order other than going for a Z program with required selection screen.
Appreciate your quick reply on this
Thank you in advance
Regards
MaheshHi
V_V2 is a collective rescheduling program as such it will do a reschedule all sales orders except for the ones with the fixed date and qty indicator set. You alternatives are:
1. Take a copy of the V_V2 program and have a programmer change it to suit your requirements
2. Set the fix date and qty flag as default in your ATP config and use transaction MASS to set your existing orders. Then the next time you run V_V2 it will ingore all your confirmed schedule lines. However, this may cause you as much trouble elsewhere than it solves.
3. If the number of sales order is not high you can manually allocate the quantities by using transaction CO06

ATP check for inbound EDI order
Hi Friends,
When I am creating outbound sales order then ATP check is getting executed properly & multiple schedule lines are getting creating in IDOC also (depending on the avaibility of stock).
But When I am trying to create the inbound sales order via EDI/IDOC there is no ATP check performed & multiple schedule lines are not getting created in sales order(as per the avaibility of stock which I am checkin thro So09 tcode).
ANy1 has faced smilier problem in past. If yes then please let me know how to solve this problem of ATP check.
PLease let me know as soon as possible.
Many thanks in advance
Br, PrashantHI Frndz,
problem is solved by using following customizing settings
Customizing:
SD/function/requirement availability/availability check/default (OVZJ)
Change the field "Rule availability" to the required value. You receive a list of the possible values using the possible entries pushbutton. Rescheduling is regarded as background processing. If you want to allow partial deliveries, choose the value 'E'. -
How to delete confirmed schedule lines, without executing the ATP check?
Sales and Distribution: Concerning ATP (product allocation)
Situation:
Step 1: An order is created with priority low. Quantities are confirmed for line items.
Step 2: A second order is created with a higher priority. No confirmed quantities.
Rescheduling program (SDV03V02) is then executed. This selects and sorts the orders in the correct order.
The confirmed quantities for the first (low priority) order should now be freed up, to be able to allocate those quantities to the second (high priority) order.
The problem I am facing is that the confirmed quantities are NOT released.
We cannot use BAPI_SALESORDER_CHANGE or SD_SALESDOCUMENT_CHANGE to delete or modify the schedule lines, because these function modules execute the ATP check again. And when that happens, quantities are again confirmed and assigned.
How can we get rid of the confirmed schedule lines, without executing the ATP check?
Thanks,
Edwin.Found a solution to the problem:
In the Rescheduling program we export a parameter to the memory, to make it possible to delete schedule lines without executing the ATP check.
Deleting of the schedule lines is done with a BAPI, which will call the ATP check automatically for ATP relevant materials. This we want to stop from happening (only when calling the BAPI).
After the BAPI has been called we FREE the MEMORY ID.
The parameter is imported again in Customer-Exit EXIT_SAPLATPC_001.
Transaction.. SMOD
Enhancement.. ATP00001
Component.... EXIT_SAPLATPC_001,
Include...... ZXATPU01.
The customer exit is used in function AVAILABILITY_CHECK_CONTROLLER, just before calling function 'AVAILABILITY_CHECK'.
Simply refreshing the ATP tables in the customer-exit, will prevent the ATP check from being executed (because we removed the list containing the materials for which the ATP check needs to be done). As a result, the function 'AVAILABILITY_CHECK' will not be processed. -
Hi All,
We're having a problem with ATP checks ignoring stock assigned to status T - Temporarily assigned stock/requirements, and double-promising against any quantity that hasn't been yet allocated to R - Reserved or F - Fixed.
For example, batch 0001 has 400 pieces allocated in F status, and 100 pieces unallocated and in A - Available status. If we enter Order 1 for 100 and save, this stock correctly moves from A to T. If another Order 2 is entered however, we are able to put up to 100 on the order and it will allow us to save. If we put 101, 100 will promise, and 1 will reject... when all 101 should reject, since 100 are already promised to Order 1 and we have no stock in A.
I cannot find anywhere in configuration where this T status is now being ignored by ATP checks. Thanks if anyone can help!
-JUS,
I suspect you may be dealing with a different issue. We are simply changing the J0 rejection to a different rejection code that won't be considered for ATP again when rescheduling is ran, since J0 is hardcoded to always take part during re-ATP.
As you probably know, J0 is set by the system if there's no availability for the item. If you want items without availability to take part in MRP I propose you either setup replenishment lead times on your materials and have your availability checking rule consider RLT, or you should have future receipts to confirm against, e.g. planned orders, production orders, etc. If you don't have sizing information yet you could use SLH methid 2 functionality.
I hope this was helpful.
Thanks!
