Hello Priydarshan,
Have you read the Note 1647157 - How to Set up Access to the SPML Service on AS Java?
Also, please be sure you have the SPML RFC at SPRO: SRM ServerMaster Data
Create Users
Activate UME-SPML Connector
When we configured it also we had some problems, and we need to use the exact name "SAPJSF" for the SPML rfc connection.
The problem with the ABAP user is because you sure have not assinged the roles SAP_EC_BBP_CREATEUSER and SAP_EC_BBP_CREATEVENDOR.
Kindly check and tell us if it helps.
SG
