CL_SALV_TABLE - refresh sometimes does nothing

jrgkraus — Fri, 18 Jun 2021 12:35:12 GMT

I wrote about this already 12 years ago (!) - https://answers.sap.com/questions/5704968/index.html - no solution so far.

I have a very strange issue with CL_SALV_TABLE regarding the refresh of a table. Since my program is very big (~100 classes) I can not paste the coding here. I will try to describe the issue with screen shots

My SALV is this table on the screen. Now, I delete the line we see and do a refresh afterwards

The delete( ) deletes the row from the database using a BAPI call. It then reloads the data in the model.

Now I step into the refresh( ) method

init_alv( ) does nothing, because the ALV object is already instantiated.

Now I step into get_data( ).

time_confirmations is the output table of my ALV. As we can see, it now is empty.

Now let's go on to the refresh:

I do a display - but also a refresh causes the same problem. Pressing F8, the table is NOT refreshed:

However, if I do a simple sort operation:

Voilà - the table is refreshed!

Now the same class has also a function (the "all confs" button), that does something very similar:

This call sets up a filtering in the model, so a different set of lines will be passed during refresh. Surprisingly, this call works perfect...

It's making me mad. I can not deliver my program like this, and I have no idea about a workaround.

Any help is welcome.

The reaction of the program seems to be a syncrhonous problem between ABAP / SAPGui, but ... you have put a flush ..

Does the table corresponding to the SALV grid is global & in the same class ?

Yes, the table is in the final class, the ALV object in its abstract super class.

I found out, that the problem relates to the fact that I do a PAI/PBO turn afterwards (with leave screen). If the leave screen is not performed, the refresh works.

I tried to change the leave screen into a CL_GUI_CFW=>SET_NEW_OK_CODE( 'ENTER' ). This resolved the problem.

I have no issue with this minimal (non-)reproducible code (double-click the line to delete):
