SD material Determination based on availability check

For SD material Determination you can create a Substitution reason and on the Strategy field, the following info. is available:

Product selection in the background is performed on the basis of the availability check.

We want to have the material determination only in case on material shortage. We expect the Substitution reason to give us this functionallity. It does not hovever take the availabilty into account before substitution.

We thought the worse case is to create a ABAP which is linked to the "requirement" field in the Procedure (OV13).

Has anyone had the same requirement? Is this a bug or just incorrectly documented?

I also encountered this abnormally recently using material determination. In order to combat the problem, the first product substitution should be for the original material. I've illustrated this below:

Original Product: ABC

Substitutes: DEF, XYZ

In order to perform product substitution ONLY in the case of ATP failure for product ABC, structure the Material Determination record as follows:

Material Entered: ABC Substitutes: ABC

DEF

XYZ

There seems to be a devaition at availability check and or on a conceptual note still.

Availability check can be configured both at requiremnt class and at the schedule line categories level.

Whilst the availabilty check at the requirement class level via global and mandatory configuration the schedule line catgry availability check deals with the order.

It is mandatory that the reqmnt class is flagged off for avlblty check and the schdelu line cat need not be.

The following are the mandatory for Availability check to happen--

1. Must be swithced on at the requirment class level and at the schedule line level.

2. Reqmnt type must exist by which a requiremnt class can be found

3. There must exist a plant and is defined

4.Checking group must be defined in Material Master records(it controls whthr the system is to create individual or collective reqmnt)

A combination of checking gropup and checking rule will determine the scope of availbaility check.

Hi Sarfraj ,

Availability check is in fact of three type

1) Material availability

2) PRT availability

3) Capacity availability

MM can use it while issuing goods , SD can use it before committing to customer ( For FG only) and we (PP) can use it while releasing prod order .

In Customizing we can define whether availability can be checked while creation of order or while releasing of order .

Also we can restrict user to release prod order if material or PRT or capacity is not available .

In MRP view you assign material to checking group . Which also decides whether to check availability individually or collectively.

Hope the answer was helpful .

If satisfied reward and close .

Hi,

Availability check is of two types as far as PP is concerned

Material availability Check

Capacity avaialbility check

You can make the system to check the availbility automatically or manually

In PP it is performed while releasing a production order,again this can be configured to check at the time of creation

While availability check system checks whether necessary stock is available for the BOM components in the respective storage location

This is controlled by the checking rule/scope of check what we maintain in the config(OPJJ,OPJK)

Similar checking rules are maintained for SD & it will come to play at the time of sale order creation

Hope this helps

Rgds,
