Reprocessing ALV screen when we click BACK button

[Former Member]

Hi,

In executable report program I am using a FM 'REUSE_ALV_LIST_DISPLAY' to display the list.

So after user selecting the records from the list and click submit it will give output results.

My question.

When he click's BACK button from output screen I need to display again ALV screen with reprocessing the list of records.

Can any one tell me how I can do this?

Thanks a lot.

Hello rajesh,

U can do like this.

First implement the USER COMMAND for the ALV list.

When the user clicks the back button modifz ur outtab with the refreshed data and set the <b>SELFIELD-REFRESH EQ X</b> and call the FM REUSE?ALV?LIST?DISPLAY again.

CASE SY-UCOMM.

WHEN 'BACK'.

Hello Rajesh

As Narendran already said you have to implement subroutine USER_COMMAND. In addition, you have to fill the <b>callback</b> IMPORTING parameters with appropriate value (see below for an example). If you want to set your own PF-status define subroutine PF_STATUS_SET, too.

I_CALLBACK_PROGRAM             = syst-repid
*I_CALLBACK_PF_STATUS_SET   = PF_STATUS_SET
I_CALLBACK_USER_COMMAND  = USER_COMMAND

These subroutines must have a <b>defined interface</b> which you can look up in the documentation of the function module. For example, subroutine USER_COMMAND (which can have any other name as well) has the following interface (see documentation):

FORM user_command  USING r_ucomm LIKE sy-ucomm           
                         rs_selfield TYPE slis_selfield. 
...

  rs_selfield-refresh = 'X'.  " refresh list output
ENDFORM.

A final remark: you should <b>not</b> use the BACK button in order to refresh to ALV list because such a behaviour is not in line with the SAP standards for user interfaces. Instead define your own REFRESH push button or handle the existing refresh button of the standard ALV pf-status in the user-command routine.

Hi,

Once the records are processed when the submit button is pressed..Modify those internal table records..then use selfield-refresh = 'X'.

FORM user_command USING ucomm LIKE sy-ucomm

selfield TYPE slis_selfield.

**Modify your internal table records here..

selfield-refresh = 'X'.

ENDFORM.

Thanks,

Hello rajesh,

No need to call the FM again .

DO what I said in USER?COMMAND form. U will be able to see the refreshed data.
