Hello Ashwin,
Kindly follow the below steps to resolve the issue here.
1) Maintain the table TBLSYSDEST in both SRM and ERP system with regards to the logical system and Technical and Dialog rfc's.
Also assign the MW_admin in the rfc user.Register the queues with * smqr.
2) Follow the sap note 720819 and maintain all the 5 tables correctly.
3) Before you start the download, you must use transaction SE38 to execute the report BBP_PRODUCT_SETTINGS_MW in the EBP system. In the 'User' field, enter the consumer name that you
selected (for example, "SRM"). Select the radio button depending on whether service products should be active or not. The report starts with the default settings in test mode.
4) Ensure that the table CRMATAB in ERP system holds the entries after the step 1. IF it is blank then follow the sap note 1498111 and run the report SMOF_FILL_CRMATAB in SRM.
5) Also check for the R3-Guid in the tables CRMMLSGUID (SRM system) and CRMPRLS (ERP system ). Both should be identical with the logical system.
6) Also refer to the SAP notes 1548622 ; 1460623 ; 872533 ; 833438 ; 588701
7) --> BD97 __ Assign RFC destinations for Synchronous method calls....
Kindly abort and load the object again, it should work fine.
Best Regards,
Rahul
