I tried to replicate BP relationship using the BUPA_REL queue from CRM to ISU, but i can see BP is getting replicated individually to ISU using BUPA_MAIN queue, but the there is no relationship in ISU with the MKK contract partner which is maintained in CRM. I maintained all the setting as per SAP best practices. Now when i checked outbound queue in SMQ1, i can see R3ABUPA* entry is stuck in SYSFAIL. when i checked sysfail error it shows "Function module "CRM_BUPA_INBOUND_REL_MD" not found", but i maintained this FM in the CRMC_BUT_CALL_FU table as per SAP best practise.
Could someone help me to sought this out? Am i missing something here, because of this outbound queue throwing this error?
