Cause: ===== When a new concept is created after copy+paste the existing concept outside of designer in Windows Explorer, this causes the GUID element in the XML schema of the two concepts schema to be same which creates the issue.
Resolution: ========== 1). Delete the concept which is causing the issue.
2). Create a new concept inside the Designer from the BusinessEvents palette and map in Instance.createInstance .
Issue/Introduction
In BusinessEvents 3.x, XSLT Mapper for createInstance does not show schema in Function for selected Concept.
