    • Hi Amol / Sarita,

      Kindly check below details.

      1. UWL Connectors : Navigation Path System Administration --> System Configuration --> Universal Worklist and Workflow --> Universal Worklist Administration.

      2. check SAP Note: 1133821 - UWL Destination Service Configuration.

      3.portal system alias & UWL connector name must be the same. (for example ABCCLNT100 is your system alias then ABCCLNT100$WebFlowConnector should be your webflow connector name),

      4. RFC destination is working perfectly or not.

      Let me know if you persist.

      Regards,

      Meghal Shah
