Hi,

Try to capture the sy-ucom of BACK button. Example:

case sy-ucomm.
when 'BACK'. "your back button command
   LEAVE TO SCREEN 0.
endcase.

Please check.

Hi,

How do you define your status? and did you assign Function code for your "BACK" button?

Thanks,

how to define status in the report? I define status using set pf-status in the report,but it does not seem to effect.In my status,I set back botton BACK.

Hi,

I think BACK is system command and it will not trigger AT USER-CoMMAND. Try to put another Function code for BACK button in your status. And check name of your status (does it contain "_" character? if yes, it won't work).

Please check.

Thanks

I have tried this method,but using this method except function code "BACK" document said.

So, please enter debug mode and check sy-ucomm when you click on BACK button.

Hi Jokey,

You cannot write your own code for handling the back button in the report program...

You said u first call a screen and then do the write statement...If that is right then correct approach would have been to create a module pool program and include the screen in there...

At the point wherein you want to display the list, use the statement LEAVE TO LIST PROCESSING AND RETURN TO SCREEN 0. This way the list would be processed and on back button you can come back to the screen that called it...

Pleae refer to the ABAP HELP for more details...

This problem is program can not go back my report instand of forward to system code,when I debug.so even I have sy-ucomm,I can write code accoding to sy-comm in my report,when I press button, the program can not goto my report excuting than code,Using "at user-comand" except "BACK" function code document said.can you tell me How?

The issue is vague.

What is the standard back button you're referring to? I mean please detailed out how you run everything. i.e. Did you start by running your report program then from there, it calls a standard transaction.

'Coz if it only calls a standard transaction, normally when back button is hit, it will go back to your report program screen.

If you're calling another screen (call screen), you just do it the PAI of that screen.In debugging mode, get what's the sy-ucomm of that BACK button, then start your coding in the PAI (LEAVE TO SCREEN 0 - this will go back to your previous screen). Elaborate more your issue if this still didn't help at all.

Hi,

First, is this a custom screen or from an ALV list? If from a custom screen, then the following might apply...

In your GUI status, did you define the function associated with the button with the Function Type Exit (E) ?

If so, pressing the button will trigger the MODULE mmm AT EXIT-COMMAND.

Hi,

You can define your own PF-STATUS and in that assign the function code for BACK button anything except 'BACK'.

The code would somewhat look like this:

SET PF-STATUS 'TEST'.

write : itab-col1,

itab-col2.

in the PF-STATUS 'TEST', assign the function code to BACK button as 'BCK'.

Now in your program you can use the event AT USER-COMMAND.

In this you can handle the functionality of BACK button.

Hope this helps.
