SAP Note 23787 - Update term. during goods receipt for purchase order

Symptom:

During the goods receipt for the purchase order with transaction MB01, the update in function module MB_UPDATE_MATERIAL_VALUES terminates, if a valuation type (EKPO-BWTAR) is entered in the unassigned order item in question although the material in question is not valuated separately (the valuation category of material MBEW-BWTTY is initial).

Cause and prerequisites

The valuation category was cancelled in the material master although a purchase order exists. This, however, must not be allowed by the system.

Solution
Please make the following changes in FORM routine MATERIAL_LESEN in program FM07MFM0:
...
IF MBEFU-BWTTY IS INITIAL.
IF NOT MBEFU-BWTAR IS INITIAL.
MESSAGE E051 WITH M-MATNR M-WERKS.
ENDIF.
IF NOT M-BWTAR IS INITIAL AND NOT MBEFU-WERTU IS INITIAL. <--- new
MTCOM-KENNG = 'MBEW '. <--- new
