Program Title Change Issue

Former Member — Tue, 24 Jul 2007 22:29:38 GMT

Hello everyone,

I have an ALV grid using classes and also included a functionality when double clicked on an line item it would take to the corresponding standard CRM transaction with the number in the line item.

My problem is after working on the standard CRM transaction when i press the back button to come back to the grid display, the program title does not change back to the grids program title instead the standard CRM transaction title remains.

Tried setting the program title when the control comes back from standard CRM transaction, but did not work.

Can somebody suggest me a solution immediatly.

thanks.

Hi Suri,

Check with adding the NO STANDARD PAGE HEADING to your program.

Make sure that you are setting the title in the PBO of the screen in which the ALV grid is implemented.

Hi,

Can you paste your code.

Now that I'm thinking about it, this is really weird, the fact that you are calling another transaction should have no effect on the calling program whatsoever. Your title should stay intacted. Can you post your code, in the PBO screen flow, as well as any modules therein, and also the event handler for your double click in the ALV. I can think of a work around, but you should have to do that. I've developed many programs just like this and have never had this problem.

The Function Module in the method takes us to the standard CRM activity transaction for the selected line item. i tried to set the title bar when it comes back from the FM but did not worl.

Again, you should need to do this, but try setting the sy-title directly after coming back.

sy-title =  text-100.

Its got to be that, not sure what is happening, but it appears that you are going to need to fire a round trip in your event handler. So try putting this coding after your function call in your event handler method.



* cause PAI
    call method cl_gui_cfw=>set_new_ok_code
          exporting
                 new_code = 'XREFRESH'.

What this should do is cause a PAI, (which there should be no funciton code in your PAI for XREFRESH), and of course will come around to the PBO, where you should be setting your titlebar as usual.

Oh dear --why do people make this stuff so complicated.

Here's an easy way without having to do any extra PBO's, or refreshing the display.

This changes both the GRID and the PROGRAM titles.

For Top of the screen you need to set the GUI titlebar before you get another display either via the grid or a programmed PBO.

In a typical grid application you don't get another PBO event after your initial call to the GRID unless you implement it in an event handler routine (and it's not normally necessary).

What you need to do after an event such as double click or whatever IS THEN set the new (or previous) title.

On the conclusion of your routine unless you code EXIT / LEAVE program the GRID will re-display. Before this display is where you need to set the title bar.

In my Double click routine method I've set the Program title to a different value and as soon as the GRID displays again the title is changed.

The GRID title has also changed -- I've shown here how to change BOTH objects.

in your main program

DATA: i_gridtitle TYPE lvc_title.

Now in the routine where you want to change the title we simply set a new title.

I also change the GRID title.

I'm going to do it in my Double click routine

in your SE41 for the program have different titles
defined
I've got 2 000 and 001.

form dubbleklik using

e_row type LVC_S_ROW

e_column type LVC_S_col

es_row_no type lvc_s_roid.

SET TITLEBAR '001'. "=========>PGM title bar

i_gridtitle = 'Grid Title Changed'.

CALL METHOD z_object->change_title

EXPORTING i_gridtitle = i_gridtitle.

ENDFORM.

in the definition section public methods

change_title

IMPORTING i_gridtitle type lvc_title.

In the implementation section
