12. Check the line where the column Description has the message Instance with same keys (x) already exists and look on the columns Service Operation, BO and BO NODE

- The Service Operation Column will give you details of what kind of actions was trying to get executed when backend raised the error message

- The BO Column tells you from what Business Object the error message comes

- The BO NODE column tells from what Node of the Business Object the error message comes

13. Check what Business Object raised the error message

- If the Colum BO maintained a ID, like YABCDEFG_HIJKLMNOPQ, error message is raised when you tried to create a new record on a Custom BO

14. Check your logic that create records for the Business Object (listed on Column BO) and change it to don't create records using ID that already exist
