ALV OO doesn't refresh the displayed data

[Marcos_F_Dotta]

Hi guys,

I developed a report using ALV and when I select an Item and press the button another ALV OO is started. So the details are displayed. But when I back and select another Item to show its details the ALV OO shows only the first details displayed before... I can't find the problem. I used the method to refresh the table when I leave the screen, but it didn't work.

So, can someone help me with any suggestion or know this problem and solved it before??

The code is attached.

Thanks!

Try flushing the ALV in PBO of second ALV using the method  CALL METHOD cl_gui_cfw=>flush.

Or you can Free both ALV gird object and Container and recreate them all the time you call the 2nd ALV.

Hi Namesh,

I tried with the method, but it didn't work. I already clear and free the objects, but it doesn't work too.

What could be the problem??

Thanks!!

Hi,

If you are using FREE abap statement for free the container and alv objects  doesn't works.

You should use the methods FREE for each class before to close the second ALV and create the objects again all the times you call it...

   CALL METHOD v_grid->free
  EXCEPTIONS
    cntl_error        = 1
    cntl_system_error = 2
    others            = 3.

CALL METHOD v_container->free
  EXCEPTIONS
    cntl_error        = 1
    cntl_system_error = 2
    others            = 3.

You first have to free the ressources used by your object before actually clearing it

Don't know if this can solve your issue but I would give this a try...

Or else post your program in .txt file so that we can try to find out the problem

I checked the code and it seems like there is no need for the OO-ABAP code to refresh the ALV display.

You already have an ALV Display with a FM Call for 'REUSE_ALV_GRID_DISPLAY' and then at the back button again the container and grid objects are being instantiated etc etc.

ALV Table Data can refreshed by just using these steps:

Step 1. Set slis_selfield-refresh = 'X' in the user_command module on REFRESH User Command (in your case BACK or whatever)

Step 2.  Add this user command to the Callback function - ZF_ALV_USER_COMMAND

The report will get refreshed with the data on Back button.

Have you checked if you have cleared the internal table before using it the second time?

Have you tried refreshing in the following manner:
