FHMI is updating stock quantity when GR to PO (F)

Question

Dear gurus,
in our system, if i do GR to PO with account assignment N to a material (material type FHMI), it is not updating the stock quantity.
if i do GR to PO with act.assignment F to the same material, it's updating the stock quantity!
the settings for the act.assignment F and N is the same (consumption posting V)
FHMI is quantity updating.
could you show me some clue on why this is the case?

Answer 1

Hi Michael,
Yes, unfortunately, the need for the storage location in this case is hard-coded in the system and I would advise you not to change it:
This depends on a System Table: T156SY: There is a field in this table (XLORT) which states whether the Storage Location is mandatory in a posting or not.
When you post to a material which makes quantity update (MENGU = X) and value update (WERTU =X) with no special stock (SOBKZ = empty), reference to a purchase order (KZBEW = B) and this purchase order is not a stock transport order (KZZUG = empty), you see the following table entries in this table:
(Note: Sorry for the wrong format!!!! but I did not manage to align the table entries here, please, check in your system the right display of the table T156SY with SE16):
BUSTR WERTU MENGU SOBKZ KZBEW KZZUG KZVBR BUSTW BUSTM XLORT
101       X          X                        B                                  WE01    ME01   X
101       X          X                        B                      A          WE06    ME02
101       X          X                        B                      V          WE06    ME02
So, as you see here, the storage location is not needed when you update the consumption (KZVBR = A or V). The storage location is only mandatory when the consumption is not updated.
If, you make the same posting but the material is not valuated (WERTU equals space), you find the following entries:
BUSTR WERTU MENGU SOBKZ KZBEW KZZUG KZVBR BUSTW BUSTM XLORT
101                    X                       B                      A         WE06     ME01   X
101                    X                       B                      V         WE06     ME01   X
So, when the material is not valuated, the system requieres the storage location as mandatory entry (XLORT = X).
The program checks the contents of XLORT, and if the storage location is mandatory and it has not been entered, then sends the error message M7 018. Once the storage location is specified in the posting, the stock is updated in the corresponding table. The consumption is not increased this time.
As mentioned previously, this table T156SY is a system table, so I deeply recommend not to make any change at all in any of the fields of this table. This setting cannot be customized either, and no user exit or BAdI will modify this standard system behavior.
In answer to your second question, if you decide to make your material as no quantity update also, then, as you say, there will be no way in the system to force it to update the quantity later.
I hope this helps you further!
Best regards,
Esther.
