A structure mismatch log entry will be generated if the serial structure is changed on a work order or on a shop order and the performed change was not valid compared to the serial structure registered in the application. You have to decide if the serial structure defined in the application has to be corrected or if it is the structure change registration on the work order or shop order that was incorrect. If you resolve the structure mismatch log entry or you decide to cancel it, a historical structure mismatch log entry will be generated. These historical entries will be marked as resolved or canceled.
