Hello Swapnil,
what is the difference between your SAP system with the SID IE4 and the others?
Did you check the application log SLG1 as described in the error message? What message is displayed there?
Help us to help you.
Best regards
Stefan

Hi stefan,
Thank you for replying.
we have performed SAP S/4HANA upgrade in IE4 from 2020 to 2021 (From SAP S/4HANA 2020), orchestrator log is : “System IE4 is no supported” for that failed run, before it was working for invoking the SAP BAPI activities and we are passing the data table as In argument. Also we didn’t find any error on sap SLG1 logs. Can you please suggest on this?
