Dependent Requirements not being created

[ramakanth_sagar]

Hi,

We use an upload program to create PIR.

BAPI_REQUIREMENTS_CREATE is used in the upload program.

Issue:

The MRP does not create dependent requirements when PIR is created using program. I get the error "BOM not selected" Exception message 52.

Where as, MRP creates dependent requirement when PIR is created manually using MD61.

Please suggest a solution. Thanks

Hello

The problem here is with the planned order BOM explosion. Are you sending any different parameter that could influence the BOM explosion when the PIR is created with the BAPI? Maybe a production version or the validity can be different...

I suggest you to read carefully the blog and make sure that the notes suggested are implemented on your system.

There is no issue with the validity and we do not use production version.

Hello

I can only tell that this is a problem with the BOM explosion. Which planning strategy are you using for your PIRs?

You can also try to run the BOM explosion manually on MD12.

It is a custom strategy. This is for Long term planning. Variant configuration with characteristic planning is used here.

Thanks

Why different behavior when created manually and when created using BAPI?

When MRP is run using MS02 (after PIR is uploaded using BAPI), it is reading each component but system is not creating the dependent requirements.
