You find inconsistencies with the field APOKZ between the tables MARC and MDMA, where this field is set in MARC table but not in MDMA table though the MRP type for the material is relevant for planning in APO. Even RAPOKZFX report will not be able to fix these inconsistencies.
The field MDMA:APOKZ will not be changed by RAPOKZFX report. This report only works with MARC table for material master. The reason for this table to be available in the MDMA table is that it has some base structure of the MARC table. However this field is not used, not considered, therefore should not be displayed. The official correction to remove the display of this (unused) field is in the following note :
1028956 : MM03 : APOKZ indicator is displayed in MRP area.
This should solve the issue with APOKZ inconsistency
