Availability check with Packing Instructions

Hi everybody:
Is possible to check the stock availability with Packing Instructions?
And if the answer is yes, what I need to do for?
I have PP, SD and MM(inventory management) I don't have WM.
Is there an special configuration in the IMG?
Thanks in advance

Availability Check with ATP Logic or Against Planning-reg

hi gurus,
what is the difference between
Availability Check with ATP Logic
or
Against Planning
means can we have two types of check?
how can we do against planning?
rajendra

Hi Prasad,
I think it would not possible to maintain to procedures at the same time for single material.
availability check against ATP is allowcation of material based on certain rules like which we set under basic functions - AC.
In this process you cant allocate the stock for specific customer.
In case of AC against planning you can allocate each and every material along with qty to specific customers.
Please see the configuration required for planning.
1. Allocation Procedure (OV1Z) the product allocation procedure is the parent of the entire allocation process. All materials that are to be included in the allocation scheme are required to have an allocation procedure assigned to it in the material master. In addition, as of release 4.0, it is in the procedure that the method of allocation is defined. The user has the opportunity to set an indicator to identify their choice of two different methods (discrete and cumulative allocation) to evaluate the quantities to be considered for product allocation.
2. Allocation Object (OV2Z) the allocation object is the root level of the allocation process where actual data is entered and planned in LIS. The object allows the user to further break down a procedure into smaller parts for future validation of components comprising a specific material
3. Allocation Hierarchy Mapping (OV3Z) Primarily, this transaction permits the assignment of an allocation procedure to an LIS information structure. Secondly, a character is assigned to the information structure to permit collective planning. Finally, the user can assign a step level to the procedure and information structure to sequence the order in which allocation quantities are checked. This functionality allows the user the opportunity to check product allocation against several product allocation scenarios, before the required quantity is confirmed
4. Define Consumption Periods (OV5Z) The allocation consumption periods functionality is only valid if the allocation method flag has been set (OV1Z). If you have de-selected the method field, this functionality is not available. The consumption window indicates the number of past and future periods to be used in the allocation check.
5. Control Product Allocation (OV4Z) In order for the allocation process to function properly, allocation control records are created primarily to map allocation procedure steps to their corresponding objects so that the allocation data records can be located for validation. Secondly, validity periods must be established to indicate when the allocation control records are active. Finally, the user has the option of establishing a conversion factor per allocation control record to accommodate BOM listings of constrained materials
6.Activate Allocation for Requirement Class (OVZ0) In order to turn on allocation in the standard order processing functionality, the requirements class must have a flag indicating that allocation is relevant.
7. Activate Allocation for Schedule Line Category (OVZ8) In order to turn on allocation in the standard order processing functionality, the schedule line must have a flag indicating that allocation is relevant
8. Create Planning Hierarchy (MC61) In order to adequately establish allocation quantities, the user must initially determine the level at which the allocation is to take place and the aggregation factor of the allocation quantities. In this step, the levels for the collective allocation search procedure are also identified.
9. Generate Masking Character (OV7Z) Upon completion of the level determination for the planning hierarchy, the collective allocation masking character must be generated to allow aggregation indicators to be established. This transaction simply reads the hierarchy established in the planning table and then generates a collective mask character for each level of the hierarchy
10. Modify Planning Hierarchy (MC62) This step is a repeat of MC61 where the initial hierarchy was established. In order to complete the hierarchical set up, the collective allocation (mask character) hierarchy must now be maintained with the appropriate aggregation factors
11. Allocation Procedure Assignment to Material Master (MM02) At the root level of the allocation process are the materials. Each material that is to be considered in allocation scenario must be mapped to an allocation procedure. In order entry, then, when a material is entered with a valid allocation procedure in the material master, the allocation data is verified prior to confirming the line item ordered
12. List of Suitable Structures (OV9Z) This report is used to identify potential LIS information structures that can be used in the product allocation process. This report simply reads through the data dictionary and selects all the active information structures that contain the field product allocation object (KONOB) as the first field. This data can then be utilized in the mapping transaction (OV3Z) to link the allocation procedure step to an information structure (previous step).
Reward if helpful.

Availability check with Purchase Requisition / Production Or

Hi,
I want to configure the availability check in such a way that, system should first check the stock available. If there is no stock system should generate the Purchase requisition or Production order.
Can you tell me the solution on the same.
Regards
Rahul

Hi,
We have the similar requirement & achieved through development.
Eg: M1- stock = 55 ea
order qtty M1- 100
system confirms for 55 ea & remaining qtty, seperate line item will be created with TAB item category i.e. 45 ea.
Used FM: AVAILABILITY_CHECK ( MV45AFZZ) & BAPI_MATERIAL_AVAILABILITY to find the ATP stock in Include:MV45AFZB

Availability check with reservation transfer

Dear all
I have a problem with availability check.
Reservation transfer, generated from processing MRP (from MRP area Z002 to MRP Area Z001).
Availability check doesn't consider reservation transfers generated from processing MRP.
if fixed the requirement, simply by saving for example, the availability check works. Of course, if I create it manually (MB21) works.
This behavior is normal?
many thanks!

Availability check with storage location

Hi experts,
I have one problem in availability check.I will explain in steps.
There are two storage locations
RMMU: main storage location where GR will happen from vendor.
WPMU:WIP storage location from where material will be issued to production order.
A is fert material.
B is bom item (raw material) and in material master maintained WPMU production storage location.
Now after sales order(100 nos) and after mrp run we will get the Planned order for 100 nos and Purchase requisition for 100 nos for material B.Now we will do the GR for "B" in Storage location RMMU.
Now we will create the Production order for ''A''.After availability check in production order ,it will show the material availability.
The problem is that we maintained the prod.storage location as "WPMU''and in that no stock is there.It is in RMMU.Still it is giving availability of material.
Requirement is it check the stock in prod.storage location i.e. WPMU
Please throw some light on it.
Thanks in advance.
Regards

Find out your checking rule maintained in Order Control OPJK for your order type and plant combination for both
Create(1) and Release purpose.
Then in t.code OPJJ and for that Checking rule and Checking group combination(Maintain in material Master) go to detail screen and don't activate check box for No Storage location inspection.
In this case system will check the available stock in Production storage location only.If it is not maintain then system will check at plant level in all storage locations.
If production storage location is not maintained either in material master or in BOM then maintain it.

Availability check with MRP area at Sloc level

HI We have MRP area at storage location level maintained for materials. Stock exists in the plant in the storage location which is part of the MRP area.
Now when I create STO and try to create delivery for the same, system is giving message 0 stock available and not creating delivery. Material has 02 Avl Chck group.If I deactivate the MRP area in the material master, it allows creation of delivery.
How can I ensure that system creates delivery even though stocks exist in MRP area relevant sloc only in the plant?
Sriram

I am sure you have already moved on from this issue, but what you mention is a limitation prior to ECC 6. You can not identify on the purchasing document the source sloc of the supplying plant. This is why you can not create the STO between sloc MRP areas. I was told this was resolved in ECC 6.

Sales orders with availability check?

Is there any transaction code to generate list of sales order /open orders with respect to availability check ( with the combination of organizational data)?. will anyone share your expertise pl.

Have you tried with VA05 where you can see tabs like
- Open Order quantity (quantity not yet despatched),
- Confirmed Quantity
- Status of the order (Partially delivered, Being processed etc)
thanks

Program position with any currency for availability check - PS/IM

Hi,
I have the following scenario:
1. Controlling area currency is USD. Local currency is BRL. We do purchase req.(CJ20n) for materials and services in USD, BRL and EUR. The P.O. is done in a second moment through MM.
2. Investment program uses USD for checking availability control. The currency for any program position is also USD.
3. System performs the availability control using exchange rate cat. "M" in OB08. We buy within one of those 3 currencies (USD, BRL and EUR), it translates to USD, and then we see how much was committed in USD.
Because of these differences between dates in exchange rates, the client wants the system to perform availability check with any currency.
For exemple: if we have USD 1000 in program position on 04.15.09 at rate of BRL 2,40 we would have BRL 2400 to purchase. If the P.O. is posted in a different date with a different exchange rate we would have more (or less) value to purchase depending on the rate, say 06.15.09 rate is 3,0 we would have BRL 3000 in local currency.
The client doesn't want this to happen. they want to commit only the first value.
They want that in IM program position would have for branch XYZ 3 different limits, one for each currency say 1000 USD, 2000 BRL and 1000 EUR. When P.R. is done it would check what currency is buying, perform availabilty check and then commit only the value requested and avoid increase or decrease values in local currency.
As long as I know IM standard doesn't work this way. Some thoughts and ideas would be a great help.
Best Regards,
Ubiratan Chaves.

Hi Ubiratan,
I understand that you are doing availability control on USD (controlling area currency), although the statement in your point 2. should be corrected - the availability control is not tied to the IM program but to the budget profile used in the project...
Availability control per transaction currency is not possible...you can have availability in controlling area currency, as you have...or in object currency (which for a project in your case would have to be local currency)...you can try this, but it only works if your project hierarchy is using the same currency (I just faced a similar issue and had to also use USD because the proejct had multicurrency WBS in it...)
Bottom line...maybe you can try "adjust" the budget to the currency fluctuations with transaction IMCRC3...the idea would be to use a specific exchange rate type that has the current exchange rate and run this transaction to "trim" the budget to the real exchange rate...
hope it helps,
Luis

Make to order availability check scenario with production order

We have a make-to order scenario where we build custom products for our customers.
In SAP, we specify a strategy group so a production order is automatically generated when an sales order item is entered. However, we sometimes create a small amount of stock, in anticipation of an order. I would like the system to first check available stock in the system, beofre proposing a production order.
Is something like thi spossible thru configuration of the strategy group, or perhaps another method?
Regards
Ken

Hi,
In SPRO->Sales and 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 the Availability check and the Checking rule combination of intrest and if you select the details,here you define that stocks that are to be considered during availability check.

Sales order availability check considering the ROH stock/procurement time

Hi Gurus,
Our client's Production process requires the availability check at order level to consider the procurement time required for the Rawmaterial (BOM component of the FERT, whose sales order is taken) in cases when this RM is not available in the plant, and Availability check should not consider this procurement time when this RM is available in the plant.
ie in first case, it should consider the total time for in-house production as well as the time required to procure the rawmaterials, along with all other times that we use like Gr processing time, packing picking etc.
In second case it should not consider the RM procurement time, but only the inhouse production time and other times as applicable.
To my understanding, Availability check at order level will only check the time given in the MRP view of the FERT, and it does not check anything about RM stock or RM procurement time.
Can you please give me some suggestions to meet this requirement of the client (client is into Food Product Manufacturing).
Your quick response will be very helpful
Thanks
Jobi

Jobi,
Our client is not following Assemble to order or even make to order. The typical production process followed is neither make to order nor make to stock.
Understood, although I am not sure why you are telling me what he has today; since your client has already told you his existing solution is unsatisfactory. I have described a solution that seems to meet the short list of business requirements that you described in your first post. I suggest you offer this solution to your client, unless he has already told you that ATO is not acceptable for some other reason not mentioned in your post.
As already mentioned by the other experts Saurabh and Kiran and Mariano, the requested functionality in general is not supported for MTS in standard ECC. As always, anything is possible through enhancement or 'workaround', as long as the client has enough time and money, and you have sufficient skills to implement.
If the client is willing to implement APO, which is the standard SAP advanced planning system, such a solution (multi-level availability checking with MTS) is possible as standard. Within the Global Available To Promise Module of APO there are a couple of ways to get at this type of ATP solution.

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
Rudy

Hi 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)
1. Define Checking Groups
Menu Path: SPRO>SD>Basic Functions>Availability Check and Transfer of Requirements> Availability Check with ATP Logic or Against Planning>Define Checking Groups
You define checking groups with which you specify the type of requirements records the system is to create when processing sales orders or deliveries
2. Define Material Block for Other Users
Menu Path: SPRO>SD>Basic Functions>Availability Check and Transfer of Requirements> Availability Check with ATP Logic or Against Planning>Define Material Block for Other Users.
3 .Define Checking Groups Default Value
Menu Path: SPRO>SD>Basic Functions>Availability Check and Transfer of Requirements> Availability Check with ATP Logic or Against Planning>Define Checking Groups Default Value.
4. Carry out Control for Availability Check
Menu Path: SPRO>SD>Basic Functions>Availability Check and Transfer of Requirements> Availability Check with ATP Logic or Against Planning>Carry Out Control for Availability Check.
5. Define Procedure by Requirements Class
Menu Path: SPRO>SD>Basic Functions>Availability Check and Transfer of Requirements> Availability Check with ATP Logic or Against Planning>Define Procedure by Requirements Class.
6. Define Procedure for Each Schedule Line Category
Menu Path: SPRO>SD>Basic Functions>Availability Check and Transfer of Requirements> Availability Check with ATP Logic or Against Planning>Define Procedure for Each Schedule Line Category.
7. Determine Procedure for Each Delivery Item Category
Menu Path: SPRO>SD>Basic Functions>Availability Check and Transfer of Requirements> Availability Check with ATP Logic or Against Planning>Determine Procedure for Each Delivery Item Category.
8. Checking Rule for Updating Backorders
Menu Path: SPRO>SD>Basic Functions>Availability Check and Transfer of Requirements> Availability Check with ATP Logic or Against Planning>Checking Rule for Updating Backorders.
9. Define Default Settings
Menu Path: SPRO>SD>Basic Functions>Availability Check and Transfer of Requirements> Availability Check with ATP Logic or Against Planning>Define Default Settings.
Availability checks
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.

What is availability check concept how it is used in SAP

hi friends,
i don't know what is availity check,how is it used and how it should be configured,please help me.

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
In Customizing, you determine whether an availability check is to be carried out against the ATP quanitity or against planning. The check against product allocations is controlled in the material master and elsewhere in the system.
Check on the Basis of the ATP Quantities
The ATP quantity (ATP = Available To Promise) is calculated from the warehouse stock, the planned inward movements of stock (production orders, purchase orders, planned orders) and the planned outward movements of stock (sales orders, deliveries, reservations). This type of check is performed dynamically for each transaction, taking into account the relevant stock and planned goods movements with or without replenishment lead time. Planned independent requirements are not taken into account here.
Check against Product Allocation
Product allocation facilitates period-based distribution of products for certain customers or regions. As of Release 3.0F, you can carry out an availability check against product allocation. This ensures, for example, that when production is low, the first customer does not get the full amount, resulting in following sales orders not being confirmed or being confirmed far too late.
Check against planning
The check against planning is performed against independent requirements which are usually created for an anonymous market rather than being customer-specific (for example, in the strategy Planning without assembly, when production occurs only up to the stocking level). The planned independent requirements result from demand program planning and are used for planning expected sales quantities independent of orders
Controlling the Availability Check in Sales and Distribution Processing
You control the availability check using general and SD-specific control features.
General Control Features
The following control elements need to be maintained in Customizing and in the material master record:
     Strategy group
The allowed planning strategies (main strategy and further possible strategies) are combined in the strategy group. As of Release 3.0, the strategy group is specified in the material master record in the MRP 1 Screen. In Customizing, strategy groups are assigned, dependent on plant, to MRP groups. If the strategy group is missing in the material master record, it is determined on the basis of the MRP group, if it has been maintained.
Up to Release 3.0, the strategy group is determined on the basis of the MRP group
     MRP group
The MRP group combines materials from the point of view of material requirements planning. This enables you to control planning for these materials in a particular way using, for example, the strategy group, consumption mode and planning period. You enter the MRP group in the material master in the MRP 1 screen. The strategy group is determined from the MRP group.
     Planning Strategy
The planning strategy specifies the requirements type for planning and customer requirements. This represents the decisive control feature for the interaction between Production Planning and Sales and Distribution.
     MRP type and item category
If no requirements type is found using the planning strategy, the system tries to determine a corresponding requirements type on the basis of the MRP type and the item category.
Until 3.0C, determination of the requirements type via planning strategy has taken priority. This is not always the best option, however, as the following example will show. A requirements type is determined for a material, which causes availability to be checked against planning. In consignment stock processing, however, availability should be checked against stock. Until 3.0C the availability check had to be deactivated in these cases. As of Release 3.0C, you can determine how the requirements type is to be determined for each transaction by maintaining the Source field in Determination of requirement types using transaction in Customizing.
     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.
Control Features Specific to Sales and Distribution
The following SD-specific control features need to be maintained in Customizing:
     Checking group
The checking group controls whether the system is to create indivdual 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.
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
Timing of the Availability Check in Sales and Distribution Processing
When you create an order, the system determines the required materail availability date on the basis of the customers requested delivery date. On this date, you must begin picking, packing, labeling, and loading the goods. Therefore, this is the date of significance for requirements planning on which the availability should be checked.
The following data is required for determining this date:
     Route from the shipping point to the ship-to party location
     Shipping point from which the goods are issued
     Loading group from the material master record
     Weight group determined from the order using the order quantity
Scheduling
This data, which you have already entered in the system, means that scheduling can occur automatically. Since scheduling is carried out backwards from the requested delivery date, it is also called backward scheduling. If backward scheduling determines that the preparation for the shipping activities should have been started already to meet the customer's requested delivery date, the system then starts forward scheduling automatically from the current date.
Scope of the Availability Check in Sales and Distribution Processing
The following elements can be included in the availability check:
     Stock
o     safety stock
o     stock in transfer
o     quality inspection
o     blocked stock
     Inward/Outward movement of goods
o     purchase orders
o     purchase requisitions
o     planned orders
o     production orders
o     reservations
o     dependent reservations
o     dependent requirements
o     sales requirements
o     delivery requirements
Requirements in sales and distribution (sales requirements and delivery requirements) result from all transactions which forward a requirement to Materials Management (MM) or to Production Planning (PP). For example, this could include sales orders or deliveries and quotations as well. Sales and distribution requirements reduce existing stock or inward movements of stock on the material availability date to ensure that other outward movement of stock elements cannot access the quantity reserved in this way.
Requirements relevant for Sales and distribution are created in Sales and Distribution, whereas other elements in this list are created in Materials Management or in Production Planning.
Defining the Elements to be Included in Check
A checking rule is assigned to each transaction. This rule in combination with the checking group controls the scope of the availability check. You can use the checking rules in Customizing for Sales to specify for the various transactions which of the elements listed above should be included in the availability check.
For trading goods it does not make sense to include planned or production orders, for example, in the availability check. However, for products manufactured by your company these orders should be included in the check.
For transactions such as make-to-order production, consignment or returnable packaging processing that create special stock, the availability check is performed against special stock.
If it is defined by the checking rules that both sales and delivery requirements are taken into account in the availability check in sales documents but only delivery requirements are taken into account in the availability check in deliveries, there is a danger that quantities reserved in the sales documents are considered to be available by the availability check in the deliveries. This can lead to sales documents becoming backlogged.
Reactions to the Availability Check in Sales Documents
If the goods ordered by the customer are not available on the requested date, the system branches automatically during sales document processing to a further screen where delivery proposals are offered for selection. The system determines these proposals on the basis of the availability situation. This screen also provides you with information on the scope of the check, the current ATP quantity, and the availability situation across all plants.
Availability Control
On the Availability Control screen, you can choose between the following delivery proposals:
     One-time delivery on the requested delivery date
In this section, the system checks whether the requested delivery date can be kept to. If stock of the material is available to make a delivery on the requested delivery date, the stock quantity is confirmed here. If there is no stock available, confirmed quantity zero is displayed.
To copy this data into the sales document, select Edit One-time delivery.
     Complete delivery
In this section, the system checks whether there will be sufficient stock for complete delivery at a later date:
o     If there is sufficient stock available at a later date to cover the required quantity in the sales document, the system proposes the date here.
o     If the system determines that complete delivery cannot be made at a later date, no date is proposed in this section.
When availability is checked including replenishment lead time, the date which is proposed in this section is the date on which the replenishment lead time period ends if the stock before the end of replenishment lead time does not cover the order quantity.
When availability is checked excluding replenishment lead time, the system bases its calculations on the stock and the planned inward movements of stock.
To copy this data into the sales document, select Edit Complete delivery
     Delivery proposal
In this section, the system checks whether and for which dates partial deliveries can be made. Partial deliveries are displayed for different dates. These dates are based on the planned inward and outward movements of stock.
During an availability check which takes replenishment lead time into account, the date on which replenishment lead time ends is displayed if insufficient stock means that no partial deliveries can be made before replenishment lead time ends.
During an availability check which does not take replenishment lead time into account, the system displays the dates on which partial deliveries can be made with the available stock.
To copy this proposal into the sales document, select Edit Delivery proposal
The dates displayed in the sections complete delivery and delivery proposal are determined from the material availability date using forward scheduling and represent actual delivery dates.
Availability Across Plants
You can display the availability situation in the various plants for which a material is maintained. To do this, proceed as follows:
1.     Select Goto Other plants on the availability control screen.
The dialog box Plant Selection appears. All plants for which the material is maintained are displayed.
2.     Mark the plants in which you want to check availability and select Check plants.
You reach the Availability Check: Overview screen. The requirements quantity and the quantity which could be confirmed as well as some additional information is displayed in a separate line for each plant you selected.
3.     If you require detailed information on the availability check for a particular line, select the relevant line and select Edit Check availability.
You reach the Date proposals dialog box where the detailed data is displayed.
4.     You can select a plant with sufficient quantity for confirmation to be copied automatically into the Overview screen. Select the appropriate line and select Edit Copy plant.
Using the user exit USEREXIT_PLANT_SELECTION in the Include LV03VFZZ you can make a preselection of the allowed plants. If you use this option, the Plant selection dialog box does not appear and the availability check is performed immediately for the allowed plants. If, on the basis of information resulting from the availability check, you want to deliver from a plant other than the one specified in the item, you must at present enter this plant manually in the item. In a later release, however, you will be able to select the plant directly from the list of plants.
Displaying the ATP Quantities
If you want to display the current ATP situation on the availability control screen, select Goto Availability overview.
Displaying the Scope of the Check
If you want to display the scope of the check (stock and inward/outward movements of goods taken into account during the availability check) from the availability control screen, select Goto Scope of check.
Delivery Agreements in the Customer Master Record
A customer may react in different ways to the fact that a complete delivery can not be provided for the required delivery date. You can define in the customer master record, the way a customer reacts to the inability to meet the requirements represented by the key data.
     The customer wants complete delivery of all items by the requested delivery date or at a later date.
The complete delivery indicator is copied into the sales document from the customer master record. To find it, select Header Business data on an overview screen or a header screen. You find the indicator in the Shipping section.
If the complete delivery indicator is set in the sales document, the individual items are automatically correlated when the document is saved if the schedule lines exist for various dates (that is, a delivery group is automatically created for the sales document items and the latest delivery date within this group becomes the group delivery date). For further information on delivery groups, see Combining Sales Document Items for Delivery.
     The customer only allows a certain number of partial deliveries for each item.
The partial delivery indicator and the number of partial deliveries are copied into the sales document item from the customer master record. To find the indicators:
1.     Go to the Business Data screen for this item.
2.     Select Edit Shipping details.
The indicators are found in the Shipping section.
Performing the Availability Check Again
Usually, an availability check is only performed when a sales document is created. If quantities or dates are changed in the document and availability needs to be checked again, the check is performed again automatically . However, you can also initiate an availability check manually.
Automatic Checks
In the following situations, a new availability check is automatically carried out:
     Quantity change
     Date change (requested delivery date, material availability date)
     Change to the fixed data
     After new delivery scheduling (for example, the route or shipping point has been changed)
     Change of plant
     Change of storage location or batch
     Removal of blocks which affect requirements
     Removal of reasons for rejection
Initiating a Check Manually
In the sales document, you can initiate a new availability check manually. If you want to perform an availability check for all items in a sales document, select Sales document Check availability on the header screen. If you want to check availability for an individual item, select Edit Item availability.
Fixing Quantities and Dates in Sales Documents
If the availability check for an item determines that the item cannot be delivered fully on the requested delivery date, and, as a result one or more schedule lines have to be created for later delivery dates, the customer can decide whether to accept these delivery dates and quantities.
You can record the customer's decision either by setting an indicator in the Fixed date and qty field or by leaving this field blank. The field is displayed both on the schedule line overview screen and on the availability screen.
Customer Accepts the Schedule Line Proposal
If the customer accepts the schedule lines which are proposed by the system, mark the Fixed date and qty field. The system then transfers the requirements for the schedule lines to material requirements planning.
Customer Requires Goods Earlier
If the customer requires the goods earlier than the date that the system can confirm after the availability check, leave the Fixed date and qty field blank. The system then only passes on the requirements for the requested delivery date and does not take the quantities and dates confirmed by the system after the availability check into account. In this case, it is assumed that the requested delivery date can be kept to because, for example, additional production capacity may become free. The system only confirms the sales order once the entire order quantity can be delivered on the requested delivery date. In the subsequent delivery processing, the sales order is only considered to be completed when the entire order quantity has been delivered or when all partial delivery agreements have been fulfilled.
A fixed item is considered to be completed once the entire confirmed quantity (which can be smaller than the originally requested order quantity)has been delivered. Therefore, it does not make sense to fix the confirmed quantity to 0 as the item is considered to be completed from the start.
During rescheduling, the fixed quantities and dates are no longer taken into account.
Blocking Confirmation of Quantities in Sales Documents
In Customizing, using Block transfer of requirements by delivery block, you can specify that certain delivery blocks in the sales document header also block the confirmation of order quantities.
If you enter such a delivery block in a sales order header, the system confirms the available quantity to show you the delivery options. If you save the document, however, the confirmed quantities are not saved. Your company could block confirmation for a customer if this customer's credit worthiness was questionable. The sales order in this case is not only classed as unconfirmed, it is also blocked for delivery.
Thus, no stock is reserved. The stock is still available for other customers. Although the order quantities are not confirmed, the system still transfers the requirements to material requirements planning. It is assumed that the delivery block will be removed at some point. The automatic transfer of requirements means that the order quantity can be confirmed at a later point in time

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
mohan

Hello,
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.
