Problem with Refreshing SALV

former_member300076 — Tue, 09 Jul 2013 08:05:04 GMT

Hi all,

I've created a SALV and put it into a container. The container is located at the left side of my screen like a dock.

Now I've added a new Function Key into the GUI Status. This new Function is the Refresh.

What I want :

Refresh my "Dock" (SALV) when the user click on the refresh button.

In order to to this I've called the refresh method of the SALV:

gr_gralv->refresh( refresh mode = if_salv_refresh=>full).

Unfortunately that not working although in debugging mode my internal table corresponding to the SALV contains the right data.

If anyone can help me

Regards,

Sam

Hi Vaman,

This statement also not working.

Something weird is happening. After the first refresh the data is correctly refreshed but after it doesn't work.

Thank

Hi,

May be you will have to check the demo program SALV_TEST_TABLE_EVENTS for better understanding of how you can use the events to refresh.

Cheers,

Hi,

maybe something like:

gr_gralv->close_screen( ).

IF NOT gr_gralv IS INITIAL.

gr_gralv->refresh( refresh_mode = if_salv_c_refresh=>full ).

ENDIF.

PERFORM select_data."load the internal table again

Best regards.

Hi,

I tried the refresh method in PAI..and it seems to be working fine..after modifying the internal table..

obj_alv->refresh( EXPORTING refresh_mode = 2 )..

Check in PBO..if you are populating the data again...

Thanks

Hi,

Thank you for your reply.

I'm doing exactly like you :

Modify my internal table
Call the refresh method in the PAI

I also check my PBO, my data isn't modified...

Hi Sam,

Your problem seems like with each click of the 'Refresh' button you are creating a new instance for the container. Me too had the same problem which was resolved when i put a condition check to verify if the container object is initial before creating the specific object in the PBO.

I would suggest to use 'IF container IS INITIAL' condition check before creating the container object and also 'IF salv_table IS INITIAL' condition check before creating the cl_salv_table object to make sure that you are creating the object only if it is not created so far. This condition checks have made the refresh function working for me just fine.

Thanks & Regards,

Sarath
