I am trying to process an inbound BOMMAT Idoc from external system to SAP in WE19 and getting the error that internal unit of measure has no language dependent settings. I tried with 2 materials with unit of measure PC and also EA but same error . It seems some settings related to CUNI or MM02 are missing. The dump says 'In perform or CALL FUNCTION "CONVERT MATNR TO INTERN_FORMAT", the actual parameter "MATERIAL' is incompatible with the formal parameter "I_MATNR". I made some entries in CUNI for PC, but error exists. Can you kindly help please.
