Refresh ALV IDA with CDS

[frankgutknecht]

Hello,

I'm using the SAP Listviewer with Integrated Data Access (ALV with IDA) with a core data service. I implemented a toolbar function to delete purchase order sets. After the user deleted a purchase order set I want to refresh the ALV to display the updated data.

How does it work?

Thanks!

Best Regards

Hi Frank,

I am not sure this is right answer for your requirements.

Previously i am faced same issue. I resolved in below manner.

After deleting purchasing order, update ALV with in new internal table & calling display function with the new internal table again.

Result came, worked fine.

Hope it is useful for you.

Thanks,

MSB.

Hello,

I'm not using a internal table, I'm using a Core Data Service. Can you provide me your code? Maybe I can adapt it for my requirements.

Thanks!

Outline Procedure flow like below.

Dispay (ALV).

Delete (

     {   

          Updated internal Table

     }

}

This might be too late for you but maybe it helps someone else.

I was searching for a way to refresh the ALV display (IDA + CDS view). Scrolling seems to read only from buffer as new entries added in the meantime on the database are not displayed. And I don't want the user to sort/filter columns only to have an update on the displayed entries.

So I added a new refresh button to the application toolbar.

In the SAP report SALV_IDA_TOOLBAR_FUNCTION you can see how to do this.

If my refresh button is pushed, an event method will be called.

In this method when the import parameter ev_fcode has the function code for my refresh button, all I do is give the table with the collected select options tables (from selection screen) again:

   go_alv->set_select_options( it_ranges = t_collected[] ).

This triggers a new DB select and new entries are displayed.

In report SALV_IDA_TOOLBAR_FUNCTION this is done too (see method  set_selection_from_toggle_stat).

Yaaay, thanks! Worked like a charm. I would not have thought of this way.
