Availablity check at storage location level in STO

Hi,

  There is an unique requirement from my client with respect to the Availability check at storage location level in STO

Process:

  Based  on the inputs from APO we are creating STR for moving the material from one plant to another plant. These STR’s will be converted into STO through ME59N batch job. During STO creation process system will do the availability check and only if stock is available in the issuing plant then only STO will be generated.

During this availability check the stock will be considered at plant level and not at storage location level.

Requirement/Scenario:

Issuing plant contains two storage location ( location A & B).FG stock exists in both the locations.

Our requirement is system should create separate line items in the STO based on the availability of the stock in the respective storage locations.

Example

Total required qty: 1000  of material X

material X - Stock in Storage location A  : 600

material X - Stock in Storage location B : 400

Two separate line item needs to be created in the STO

Is there any function module available for doing Availability check at storage location level so that it can be called in ME59N with the enhancement.

Please suggest how to achieve this. If any enhancements needs to be done we will do it.

Thanks & regards,

Prashanth
