Hi EVGL,

As per below link

I followed Every step of above link but part of Coding the Outbound Exchange is done upto table level methods(CanXMLsent and Sendelectronically) and clicked method which is have to created in form level is not done because i hav to generate XML automatically after the completion of insert data into tables by another class(which is not related to this topic)...So i have done that part too..while running the code in the job fetched the current record and called the CanXMLsent and Sendelectronically methods but in Queue Manager I found the Error of No Valid document Identified from the Entity Key...Can you plz tell the solution for this...thanks
