Stock/Requirement List API

Hello,

I guess we all faced the same issue. Sometimes you need to collect

data from stock/requirement list for reporting topics. A wrong

approach would be to try to select data from database and reproduce

standard calculation. This is almost impossible due to the complexity

of the current MRP design, moreover if you do that it will be more

complex to explain the calculation to the users and of course to fix

issues. The second option is to follow SAP strategy and use service/

API for this purpose.

In standard SAP, we have function module MD_*_API (sorry I don't

remember right now the exact name :-(, in AFS we have

J_3AM_DISPOSITION_DISPL. The standard one calls the AFS FM and then

performs a mapping between standard MRP element and AFS MRP element.

Standard and AFS stock/requirement list are based on those functions.

In release 6.0, view filter was added to AFS MD04, which is nice,

however from my opinion the best thing would have been to add

selection rules as this speed up a lot data processing. If you just

want to pick up supply elements (whatever the MRP status), SAP always

load everything such as demand & supply. In standard, selection rules

are filter before database selection.

Of course, I understand that this kind of changes would require an

effort in the AFS PP-MRP are.
