      ....fieldexit parameter is set to no //

      I didnt get you .

      For this scenario the processing is to validate the cheque number from the Ztable and check the status whether cleared or not and then error message.

      if u write a select and validate with the ztable field why it is failing ?

      //my requirement is that if user enters cheque number in reference then the cheque number shud get validated from zcheck table

      in the code where are u validating the ztable content ?

      No select on Z table ?

      check if u have to do some more coding ..

      regards,

      vijay.

      FUNCTION FIELD_EXIT_XBLNR1.

      *"----

      ""Local Interface:

      *" IMPORTING

      *" REFERENCE(INPUT) TYPE XBLNR1

      *" EXPORTING

      *" REFERENCE(OUTPUT)

      *"----

      data : begin of it_bkpf occurs 0,

      xblnr like bkpf-xblnr,

      end of it_bkpf.

      select xblnr from bkpf into corresponding fields of table it_bkpf .

      READ TABLE IT_BKPF WITH KEY XBLNR = INPUT.

      IF SY-SUBRC <> 0.

      message 'Please Enter correct reference No.' type 'E'.

      ENDIF.

      ENDFUNCTION.

    have you use any field exit for that? if no then run the report RSMODPRF and give your fields data element name and create the fn module and assign program name and screen no. activate that. it may work...

    activate the fn module first.

    now come out of fn module builder and run rsmodprf again in selection screen dont specify anything.

    run that it will show all the field exits.

    assign prog name and screen no.

    choose your fieldexit and activate it from the menu bar.

      His problem is that the exit cannot be activated if the ABAP/FIELD EXIT system parameter is set to no. This is a system parameter and requires SAP to be restarted as mentioned in the Long message text. If the BASIS guy's won't set it to yes, you won't be able to use field exits as I see it, you'll have to find an alternative method.
