Material Master Enhancement End-to-End: Conversion Perspective


Maintain Structure Relations

Maintain Field Mapping and Conversion Rules  


Execute the LSMW object after finishing all subsequent steps like Specify Files, Read Data, and Convert Data successfully  

Start IDOC Generation


Start IDOC Processing


Result for Point Number 4  

Maintaining customer specific fields through IDOC Method  

All the steps followed for BAPI method above also applies for IDOC method in the similar manner. Same IDOC Basic Type: MATMAS_MASS_BAPI03 and Message Type: MATMAS_MASS_BAPI will solve the purpose. Only LSMW object attribute technique will be different.  

Remaining all steps, mapping, sequence of execution and result remains same as BAPI method.  

Table TBDBE speaks about the link between Message Type MATMAS_MASS_BAPI to BAPI_MATERIAL_SAVEREPLICA
