Error : Field wa_name does not exist in the form

Hi Experts,

I have a query similar to your original post but don't know exactly how to proceed.

When i am trying to issue Delivery output for T code VL02N after selecting Output type e.g. 'ZABC'

and then selecting print preview, it gives following error.Please see the screen shot :

I have checked the driver program as well as smartform thoroughly , wa_name has not been declared any where.

I tracked down the place of error and it coming from FM 'SSFCOMP_PROCESS_DOCUMENT'

CALL FUNCTION 'SSFCOMP_PROCESS_DOCUMENT'

        EXPORTING  HEADER            = %HEADER

                   DOCSTRUC                   = %DOCSTRUC

                   STARTPAGE                  = CONTROL_PARAMETERS-STARTPAGE

                   ARCHIV_INDEX_TAB      = %ARCTAB

                   MAIL_APPL_OBJECT      = MAIL_APPL_OBJ

        IMPORTING  RESULT                = %RESULT_PD

        EXCEPTIONS OTHERS              = 1.

   IF SY-SUBRC <> 0. PERFORM %RAISE. ENDIF.

   DOCUMENT_OUTPUT_INFO = %RESULT_PD.

SY-SUBRC becomes 1, consequently it raises above error using subroutine %RAISE.

Interestingly, when i pass same data to the FM for different Outbound Delivery No., it does not show any error.

In this case SY-SUBRC is EQ zero. and smartform print preview gets processed successfully.

Dont know how to track down the error, please let me know the solution to eliminate this.

Best Regards.
