Perform under function

Former Member — Fri, 04 Jul 2008 04:44:37 GMT

Can I use Perform and Form inside a function module.

I have created one function in se37 and I am using perform and form in its source code, but the system is giving me the following error msg.


Incorrect nesting: Before the statement "FORM", the structure
introduced by "FUNCTION" must be concluded by "ENDFUNCTION" . . . . . .

hi..

use the form ....endform...after the endfuction...statement..

In case of functions...u have to write the subroutine in that way only....

Hi Prakash,

Give the subroutines (form ....endform) after end function.

Hi ,

You can do that .. but your form .. Endform should be after endfunction..

Hi,

You can write a perform statement in the FM. Write the Subroutene Perform < Subroutene Name>. Double click on the Subroutene the controle would take you to a new include.

Hope this will solve your problem.

Reward with out fail if found use full.........!

Cheers,

Rama.

U can write performs/ subroutine calls in function module and declare an inlcude and write the forms/subroutine code inside that.

Hello Prakash,

Yes, of course you can but make sure you write the code between the FORM and ENDFORM statements in a separate Include program provided in the Main Program (menubar GoTo->Main Program) whose name ends in FUGRF01.

See example below for detailed explanation:


FUNCTION zpa_pa_wb_outbound_empl_iface .
    PERFORM convert_dates CHANGING lt_wb_file.
........[ ]
........[ ]
........[ ]
ENDFUNCTION.

From this FM, click on Menubar, GoTo->Main Program. Here you'll see something like this:


*******************************************************************
*   System-defined Include-files.                                 *
*******************************************************************
  INCLUDE lzpa_pa_qh_wb_empl_fugrtop.        " Global Data
  INCLUDE lzpa_pa_qh_wb_empl_fugruxx.        " Function Modules

*******************************************************************
*   User-defined Include-files (if necessary).                    *
*******************************************************************
* INCLUDE LZPA_PA_QH_WB_EMPL_FUGRF...        " Subprograms
* INCLUDE LZPA_PA_QH_WB_EMPL_FUGRO...        " PBO-Modules
* INCLUDE LZPA_PA_QH_WB_EMPL_FUGRI...        " PAI-Modules

Delete the comment (*) of the first line under "User-defined Include-files" and change it to the following:


INCLUDE LZPA_PA_QH_WB_EMPL_FUGRF01.

Double click on the name of this include to create it, then write your own routine in this include, see below the example the coding in LZPA_PA_QH_WB_EMPL_FUGRF01:


*&---------------------------------------------------------------------*
*&      Form  CONVERT_DATES
*&---------------------------------------------------------------------*
FORM convert_dates CHANGING pt_wb_file TYPE tty_wb_empl.

  FIELD-SYMBOLS: <fline> TYPE ty_wb_empl_struc.

  DATA: lv_wb_begda TYPE begda,
        lv_wb_endda TYPE endda.

  LOOP AT pt_wb_file ASSIGNING <fline>.
    lv_wb_begda = <fline>-start_date.
    lv_wb_endda = <fline>-end_date.
    <fline>-start_date = zcl_hr_utilities=>conv_date( lv_wb_begda ).
    <fline>-end_date   = zcl_hr_utilities=>conv_date( lv_wb_endda ).
  ENDLOOP.
ENDFORM.                    " CONVERT_DATES

Now, Activate all your Includes including your main program and function group and module.

This is the correct way of writing a subroutine within a function module.

Hope this helps,

Cheers,

Sougata.

But I am using perform and form in the source code that is present in se37 only

Re: Perform under function

Former Member — Fri, 04 Jul 2008 05:19:32 GMT

if you want it in the same Fm, write the form end form after ENDFUNCTION. and the perform should be between FUNCTION-ENDFUNCTION.
