When copying one routing revision to another the attached documents are not copied

Go to the Engineering >Routing > press the command button Copy Routing Revision function in Aurena / IEE and that have attachments in the routings operations attachments are not copied to the newly created Routing operation.

Based on the initial technical investigation , it was observed that when we click the Copy Routing revision button, the application calls to routing_operation_list_API.copy_routings . This function has a parameter called, copy_attach_documents . If this parameter received "1" as the value ,the document should copy. Accordingly, from the application level the specific values passes but from the database level this is not happening.
