When i am trying to take the print of production order by T.C CO02, System is throwing the error, "START_FORM is invalid.OPEN_FORM is missing (Message No. TD 423).
Diagnosis:The specified function has been called although an OPEN_FORM was not executed beforehand.
Procedure: Plz check the use of the SAP Script program interface in your program.A print procedure must be initiated with OPEN_FORM before the specified function can be executed.
Guys any idea how to sort the problem.
