Availability Check & MRP

Dear All,
I need your inputs in the following scenarios:
a) Availability Check
b) MRP
I know some details about customizing these from SD Point of view(IMG>SD>Basic Functions).
I need to understand logically why and where these are used in SD Flow / SD Module.
Kindly give your suggestions to understand these in a better way.
I would be greatful to you if you can provide me the links or sources wherein I get the information regarding these.
Regards,

Dear SD
a) Availability Check
When you enter a sales order, you can only confirm the delivery of the goods for the required delivery date if the goods are available for all the necessary processing activities which take place before delivery:
The shipping department must ensure that freight forwarding or another shipping company is advised early enough so that sufficient time remains for packing and loading to be carried out. An availability check can be carried out on the deadline date for availability for the goods.
The procurement department must ensure that the production and purchasing departments are advised of inadequate stock quantities so that goods can either be produced punctually or ordered. Sales transfers the information on materials ordered as requirements to material requirements planning. Requirements are planned outward movements of stock. The transfer of requirements informs production that goods must be produced, or advises purchasing that purchase requisitions have been created for which purchase orders must be created and sent to the suppliers. An availability check can only be carried out if these requirements are transferred.
b) MRP
The main function of material requirements planning is to guarantee material availability, that is, it is used to procure or produce the requirement quantities on time both for internal purposes and for sales and distribution. This process involves the monitoring of stocks and, in particular, the automatic creation of procurement proposals for purchasing and production.
In doing so, MRP tries to strike the best balance possible between
optimizing the service level and
minimizing costs and capital lockup.
The MRP component (PP-MRP) assists and relieves MRP controllers in their area of responsibility. The MRP controller is responsible for all activities related to specifying the type, quantity, and time of the requirements, in addition to calculating when and for what quantity an order proposal has to be created to cover these requirements. The MRP controller needs all the information on stocks, stock reservations, and stocks on order to calculate quantities, and also needs information on lead times and procurement times to calculate dates. The MRP controller defines a suitable MRP and lot-sizing procedure for each material to determine procurement proposals.

MRP Availability check

Hi All,
I am running MRP for a Assembly which is to be assembled by a subcontractor. MRP run should create PR for child parts of Assembly(Finished Goods). MRP type is PD and Strategy is 10 and availability check for Assembly (Finished Goods) is KP and for child parts is 02.
The Purpose of MRP run is simply creating PR for child parts (Raw Materials) as per Plan given in Demand Management table (MD61)
PRs are getting created sucessfully after MRP run but I have issue with Assembly parts (Finished Goods).
MRP requirement calculation should not consider stock of Assembly and it should also not consider subcontracting Purchase order of Assembly parts (Finished Goods)
Currently it is considering both. How I can avoid this . MRP calculation should consider only Plan given in Demand Management table.
Thanks
Sanjay
Pls. refer thread posted earlier
Re: MRP Availability check

Hi,
In the scope of check OPPJ for the assembly exclude the sloc stock by
activating the indicator No sloc stock inspn for assembly.
For Subcontractor stock In OPPJ activate the indicator W/O subcontracting
ie you need to define two scope of checks.
You use the logic of Material Provision indicators.

Block Stock consider during MRP Run and Stock availibility check

Dear All,
I am facing the stock availibility check , Sytem consider the Defective material which is Block in same storage location ,and system not generate the Planned order .
-Blocked Material stock 100, and requirement 100 then system not generate the planned. Client need the system generate planned order 100 , Because 100 material is defective.
I have configured the system scope of availibility , Block stock check remove , but problem is not solve.
Thanks
Rajesh Tiwari

Dear ,
Can you please re-check your MRP plant parametrs in OPPQ wether you have selected blocked stock( Available Stock tab ) option by chance ?
Please de-select the same and re-run MRP.Generally MRP does not consider block stock in net requirement calcualtion .One more thing , MRP does material avilablity check as per OMJJ set up ( define availbality chek ) but does not consider the same while doing net requirement calcualtion to generate PR rather it goes down to MRP plant parametrs ( oppq or oppr )
Hope this is clear

Materials in stock at u loc consider for Availability check but not for MRP

Dear ALL,
Please solved the problem by settings in the customizing we are able to set the materials at stock U location (serviceable )should not be considered in Mat Availability for PM orders
Settings we have made for all storage locations in U * By excluding storage location stock from MRP
If storage location stock is excluded from MRP at plant level, no receipts for this storage location will be created in the planning run.
so we are able to run the availability check perfectly
But now MM dept.is not accepting this as they want this stock to be considered for MRP
Has anybody done this scenrio successfully please reply the solution
Regards
Pratap

A way that I think of, is to set the ATP at SL level, so in PM order you check only in a specific location, not in all the plant.
Of course that you need to let all SLs to be relevant for MRP, otherwise this stock is not considered for planning.

Vendor Stock - MRP availability check

Hello,
in my current project, we would like to see the vendor stock in SAP. We would like to modelize it with purchase requisition or consignment stock on a specific storage location.
The problem is that we do not want to take in account this stock for MRP calculation. So it possible to exclude one storage location of MRP calculation (storage location MRP indicator in MRP4 view of material master). It is working.
But we you activate this setting, the availability check is not working anymore for this storage location for one production order. And we want that this vendor stock on this storage location is taken in account for material availability.
If anybody know how to activate availability check on production order when the flag "storage location excluded from MRP" is activated, do not hesitate to answear.
Thanks in advance

MRP planning and Availability check

Dear Friends ,
We are updating Availablity check in the MRP view for all materials in materials master , While running MRP system is considering ATP check as per SPRO settings defined for Availablity check group .
Weare not conclude what is the relation for MRP run and availablity check , or any seperate SPRO settings available for MRP on availablity.
If we not assigned the Availablity check in MRP view what will happen if during MRP run ?
thanks & regards
Suresh Babu.S

Suresh,
MRP does not look at what you have configured for Availability check. These two are independent from each other.
As given in Help,
In the planning run, the system carries out the following partial processes:
1. The system checks the planning file entries. Here, the system checks to see whether a material has been changed in some way relevant to MRP and should therefore be included in the planning run (see Checking the Planning File Entries).
2. The system carries out a net requirements calculation for every material. Here, the system checks to see whether the requirement quantity is covered by available warehouse stock and fixed receipts from Purchasing or production. If the requirement quantity is not covered, the system creates a procurement proposal (see Net Requirements Calculation).
3. Then the system carries out the lot-sizing calculation. Here, the system takes the lot-sizing procedure and, if necessary, the rounding up or down values into account (see Lot-Sizing Calculation).
The system carries out scheduling to calculate the start and finish dates of the procurement proposals (see Scheduling).
4. The system determines the type of procurement proposals. Depending on the settings, the system creates either planned orders, purchase requisitions or schedule lines for a material (see Determining the Procurement Proposal). If you have maintained the necessary specifications for procurement quota arrangements, the system determines the source of supply which it assigns to the procurement proposal (see Quota Arrangements).
5. The system recognizes critical situations which the planner has to processes manually in the planning results. For this purpose, the system creates exception messages and carries out a rescheduling check (see Creating Exception Messages and Rescheduling Check).
Availability check is not a planning process, it is basically a CHECK, based on the Scope of check derived for that Particular transaction, system check the availability of a material and it can confirm or propose the possible availability date.
In short if a material is defined with Check Group "KP", but with MRP type PD, still MRP would creates procurement proposals if the demand is more than the stock+recipets.

Prasobh

MRP and Availability check clarification

while browsing the forum, many experts here mentioned in old threads that MRP and availability check are two different (independent) concepts. I am really confused on this one. let me put my understanding here and plz experts help me if I am wrong with a figurative explanation, so that will be easy for understanding.
Assume this is the scenario as of today.
Plant stock for material x u2013 100
Reservations for material x u2013 70
Incoming receipts for material x u2013 50
So net stock = 100 + 50 -70 = 80
sales order arrived for material x u2013 100 and availability check is done. Results of availability check says 80 can be confirmed and 20 can be confirmed on later date.Transfer of requirement for quantity 20 is done to MRP. Mrp runs and creates planned order for 20.
In the availability check config ovz9 if I say donu2019t consider reservations, then when availability check is done for 100 quantities..system will confirm 100 because available stock according to system will be 100+50 = 150. So transfer or requirements are not sent to mrp.
So isnu2019t mrp run directly dependent on availability check?

925,
sales order arrived for material x u2013 100 and availability check is done. Results of availability check says 80 can be confirmed and 20 can be confirmed on later date. Transfer of requirement for quantity 20 is done to MRP
No. 100 pcs requirements are passed to MRP.
In the availability check config ovz9 if I say donu2019t consider reservations, then when availability check is done for 100 quantities..system will confirm 100 because available stock according to system will be 100+50 = 150. So transfer or requirements are not sent to MRP.
No, 100 pieces requirement are passed to MRP.
This behavior depends upon how your 'transfer of requirements' is configured, which is an SD setting. Normally, unless the fix date qty field is set in the sales order, the entire 100 pc requirement is passed to MRP in all cases. The assumption is that you have accepted the sales order and will 'some day' need to issue and sell the parts. You need to begin planning for this event now.
When MRP subsequently runs, it will net out the supply elements (stock and inbound reservations) and will from this calculation determine how much needs to be built. It then proposes a solution (planned order or purchase req).
ATP check seldom has much impact on MRP. You are correct in realizing that the ATP check must be consistent with MRP and with your chosen MRP strategies, in order to provide an end-to-end business process that is logical and meets all business requirements. However, in SAP these two functions are separate.

Availability check Problem in sales order according MRP sterategy

hi,
We are using strategy 56 for configurable final product and strategy 65
for its variants.Requirement type is "ELV V". According this requirement type,
it is not possible to confirm availability check and then deliver the
sales order. We tried to mark availability check for requirement type ELV V in OVZG Tcode, but the
following error came up: "Check against plan material can only be carried
out w/o avail.check". Is there any setting to handle this problem to work
with strategies 56 and 65? Is it some configuration that we forgot?
Thanks,

Yes, We have maintained planned del. time. and other fields also,
My problem is that, To make assembly of material A we have two component material B and C.
in the sales order of material A, system should check availability of component material B and C.
please help

Creation of Sale Order for configurable material with availability check.

Hi,
We have a scenario in which the material is configurable. The configurable material (X) has few variants (Ex: X1, X2, X3, X4, X5). While booking the sale order, we use the material number (X).
Further, the material planning is done for the variants X1, X2, X3, X4, X5. The standard variants are planned for production in advance.
1.     While booking the sale order, we want the availability check of the stock (type matching to happen). What needs to be done in configuration?
2.     While booking the sale order, there is a possibility that the configuration selected will not match with any of the standard variants due to some additional requirements of the optional features, in such cases how to link the standard variants to the sale order & create requirement for additional requirements.
Regards,
Umesh

Hi Umesh,
           1.Create material master for configurable material and variants in mm01.
           2.Maintain BOM for the configurable material in CS01
           3. Configur the variant configuration steps
              a. Create charecteristics T.code CT04
              b. Create values and assign classes
              c. assign the values to charecteristics
              d . Maitain dependence T.code CU01
              e.create configuration profile t.code CU41
              f.stimulate the configuration profile.
4. Do the availability check configuration through this path
IMG --> Sales and distribution > Basic functions ,> Availabilty check and Transfer of requirements.
5. Maintain the Availbility check field and MRP views in the material masters other wise you sit with PP people and do that
I hope it will help you

Availability Check not working for Item Cat TANN or YG05 in Btch Split

Currently working on implementing Automatic Batch Determination (BD) project and one fine piece is holding up the implementation (make or break for project).
In our QA System:
- In inventory we have a quantity of 2 for a material: 1 in one batch and 1 in another batch.
- Create an order with 2 line items with the same material number for a quantity of 1 each. Line item category is TANN
- When you generate the delivery the batch determination causes the items to split (even though you have a quantity of 1 in the line item).
- When you go into the delivery and open up the 1st line item and look at the 900001 line, BD chooses the 1st batch for a quantity of 1. Line item category is YG05.
- When you open up the 2nd line item and look at the 900002 line, BD chooses the 1st batch again, NOT the 2nd batch which it should.
If I change the line item category on the Sales Order to TAN and generate the delivery, BD correctly assigns the 1st batch to the 900001 line item and the 2nd batch to the 900002 line item. Which is correct.
Now for the strange part. The TANN item category and BD works find in our DEV Sandbox, but NOT in our QAS system.
I have spent two days now trying to find out where Availability Check is assigned specifically to Item Categories and any differences between our DEV Sandbox and our QA systems to no avail.
Our customers need the ability to be able to put the same material number on multiple lines of a sales order due to special pricing per customer within an order.
Can anyone direct me to some configuration or transaction that controls Availability Checking by Item Category. I have checked the 0VLP transaction and they are identical between our DEV and QA system for the TANN and YG05 categories.
Any help will be greatly appreciated.

In VOV6 the 'CP' Schedule Line Cat. has the Availability flag check. There were a few areas where I found an "Availability" flag and made sure there were all set.
But, I did finally find out what the error was:
Logistics Exec -> Shipping -> Basic Shipping Functions -> Avail Check and Transfer of Requirements -> Transfer of Requirements -> Determination Of Requirement Types Using Transactions
There are entries by Item Category. For
I/C = TANN
MRP type = PD
the Requirement Type was missing (if you look at the entry for TAN/PD you see an 11 in the RqTy column).
So I entered a 11 (Delivery Requirement) into the field and now the Availability Check works and I am getting the correct Batches and quantities during Batch Determination.
There is no entry for the YG05 batch split, so I guess the system just uses the Item Category of the main line item.
Thanks for the responses. Sorry to bother you I should have figured this out earlier.

How to execute availability check against delivery date in purchase order

Hi all
In MD04, I know that "available date = delivery date in purchase order + GR processing time" & "GR date = delivery date in purchase order". When I execute availability check in production order, I will get material's committed date = available date. But I hope to get material's committed date = GR date in purchase order.
For example. delivery date in purchase order is 2012/02/06 and GR processing time is 2 days. After ATP in production order, I will get committed date 2012/02/08. But I hope it show 2012/02/06. How to customize it.
(The GR processing time must be set 2 days for MRP calculation. it can be changed to 0.) Thanks!!

Hi Rita,
One Doubt, If you say that material commited has to be the GR date and you do not wish to wait for GR processing time, then why do you have the GR processing time in first place.
For ex. My client, we get the stock as per GR in Quality inspection and so we have GR processing time considered for available time in MD04. But since the business considers the Inspection stock as avialble, The stock gets reflected in avialibility check the moment GR is done.
So please explain your requirement in detail. There could some way to do so. If not the raise an issue with SAP.

AFS material availability check

Hi Experts,
Please help me in following.
I have stock for my AFS material in unrest.use. Even system create Purchase order when I run MRP for requirement of Sales order.
Vipul.

Hi Vipul
Please check in the MRP views what is the procurement type in the material master:
It should not be F.
Also check the transfer of requirements in SD basic functions wheteher it is activated in the requirement class and the schedule line level.
Also check whetehr the Availability check you have defined the availabilty control in the MRP material master screenas individual requirements.
Hope this will be helpful.

Availability check on storages in sales order and delivery documents

Hi all,
I'm verifying if it's possible to find a standard or a custom solution for this type of problem:
I have a scenario in which there are more storages relevant for MRP (ex. 01, 02, 03, 04), and, in if I check availability in sales order or delivery (using checking rules "A" or "B") with setting which considering storages location inspection in availability check control, system check if there's stock available on all these storages.
I'm trying to verify if it's possible to consider only some on these storages (ex. 01 and 03 only) in sales order and delivery documents availablity check.
I know that in sales order storage location field is normally filled only using exit, but i don't know if it's possible to do, using a user exit, check availability considering only some storages and not all. At delivery level i have tried to use stock strategy, but this functionality don't have consequences on availability check, also if it's relevant during good issue phase.
Any suggestion will be appreciated.
Regards
Gianpaolo

Hi Gianpaolo,
We had some issues with availability check on a Customer Site.
I don't remember right now if we had to exclude storage locations from MRP to take them out from ATP, but I guess Shiva is 100% correct.
At the end, what was done was to always "force" a unique storage location in the sales order item, which will be the storage location used for shipping of the delivery of course.
If you use WM in your plant, then you will have no problem in having a unique storage location, so no problem.
Anyway you are correct in your analysis, if the Storage location is not informed in the sales order item, then all the plant stock is taken in account for ATP.

What's the relationship between Availability check & Individual/coll.?

Hi,
In the material master (Tcode MM02), how does the following parameters affect each other?
<b>MRP 3 - Availability check</b> (01 Daily requirements, 02 Individ.requirements...)
<b>MRP 4 - Individual/collectively</b> ( Individual and collective requirements,1 Individual requirements only, 2 Collective requirements only)
Thanks and best regards.

AIR is a runtime that supports a superset of the Flash Player API. You use it to run mobile and desktop applications, as opposed to browser apps.
Flex is a set of technologies for building either AIR apps or browser apps. It includes a framework of runtime classes (e.g, Button, DataGrid, etc.) to use in your applications, an SDK with a command-line compiler, and an IDE called Flash Builder (formerly Flex Builder) that supports intelligent editing, a design view, and a debugger.
So, a brief statement of their relationship is that you can use Flex to build AIR apps.

Stock confiramtion at sales order level for future date- Availability Check

Hi all
Here is the scenario
This setting is available in the system:
Stock is available
Sales order created with Requested delivery date in future-> not confirmed
Sales order created with Requested del date today -> confirmed
The requirement :
how and where to change this setting in IMG so that also orders with Requested Delivery Date in future are confirmed if stock is available.
As this is urgent request to respond quickly.
Regards
Devender

Hello Devender,
You can achieve the mentioned scenario by configuring ATP. You can do ATP with RLT or ATP without RLT.
In ATP with RLT, system will check and confirm the quantities from existing stock only and if quantities are insufficient then the system will consider inline POs or manufacturing time to confirm remaining quantitites.
Else you will be getting schedule lines for only items in stock and remaining will be unconfirmed as ATP without RLT will be activated i.e., system will check and confirm the quantities from existing stock only.
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Availability check with ATP logic or against planning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.
Reward points if helpful.
Regards,
Priyanka
