ALV and transaction variant

himanshu_gupta2 — Fri, 21 Feb 2014 08:32:18 GMT

In my ALV report i have some buttons like display, edit , duplicate for the service notifications ( IW5x)

In this button i called the transaction through variant (SHD0 ) using FM " RS_HDSYS_CALL_TC_VARIANT".

These function are working fine.

Problem persists

1) when i click on these button and click on back , it will back to my ALV report

2) when i double click on alv row , it open the IW5x transaction and when i click on back button it back to my method double_click and show the transaction again.

3) if click button more then it will display the transaction that many time.

anyone have idea about what is going on ?

Hi,

You can't do anything about it. This is because once you call a standard transaction, the control goes over to the standard program. User command 'BACK' in standard program decides how the system should react. In most cases, it goes back to the screen calling it.

Please note the solution provided below is not recommended.

In case, you want to change the behaviour, find some implicit enhancement in the PAI of the standard screen and change the code. There you need to check

If sy-calld = 'X' . "Called by call transaction

and sy-cprog = 'your program' ".

** Your expected result on clicking the back button

endif.

Regards,

DPM

Hello ,

thanks for the reply ,

But problem is not in the standard code.

Problem is that my event double click will automatically trigger by number of time = i go to transaction varaints through button.

note: in doulble click also i call the same transaction variant.

Hi Himanshu,

It is problem for not clearing/refreshing variables using before calling transaction.

Thanks and Regards

Hello srimant,

could you please elaborate ... which variable ??

After i edit a couple of entries or any other function on my application toolbar button , and then double click on the notification , then in notification screen ,the back button does not go back directly to the ALV. Instead it keeps on moving back to n times(no. of times i clicked on edit button).

Problem has been solved now.

I dont know why the double click event is called every time.

I just make sure that double click event will only call when the ALV grid object will create.

If anyone knows the reason behind it please share.
