Hi, Randeep,
The CLFMAS idocs with field OBJEK with only material number, are material classifications. They are generated from Table: MARA.
Since GBT only expects material/batch classifications to process (classifications from Table: MCH1 or MCHA). Therefore, you can filter such classifications out from ECC - just don't send them.
How to filter non material/batch classifications out in ECC?
SAP Transaction: BD64 - Distribution Model:
Sending System
Receiving System
CLFMAS
Data Filter active: Class Type: 023, Table: MCH1 & MCHA.
Best luck and regards,
Lilly
