No entry in key field of table MARM
I am trying to import and create a Article Master using LSMW with IDoc method. ARTMAS IDoc is getting generated but it is showing error as No entry in Key field MARC, MVKE, etc etc and now finally stuck in No entry in key field of table MARM even after filling all possible data.
Function Module used here is BAPI_MATERIAL_MAINTAINDATA_RT. I don't know any technical aspects here to look into.
Kindly help me out with the information on what could have gone wrong here and what are the possible solutions?
Thanks & Regards,
