Summary :
When using Transaction MC84 to create a product group in SAP, users might encounter the error MG144 after entering all required fields and pressing ENTER. This happens if SAP Note 592229 is implemented without proper customizing of the material master. To fix, review the field settings in Transaction OMSR, and ensure correct field references for material types in Transaction OMS2. Fields utilized in MC84 should be set as required. Set the material type for planned product groups to "PROD", and note the special handling of fields via BAPI_MATERIAL_SAVEDATA, affecting field references MAL1 and MAL2. Alternatively, use MM01 for creating product groups.
Key words :
system issues error message mg144, create product groups exclusively, required entry fields, field selection sees, field references mal1, create product group, mg144 reason, required field, product groups, product group
