Change it_outtab after the first display (ALV grid)

Question

Is it possible to change the it_outtab , ie the data of my alv without destroying it?

I know that to change the field catalog it is possible with this method:

CALL METHOD gr_alvpl->set_frontend_fieldcatalog
  EXPORTING
    it_fieldcatalog = gt_fldct.


CALL METHOD gr_alvpl->refresh_table_display( ).

But if I have to change the it_outtab parameters, is it possible?

Answer 1

Yes. Use the method REFRESH_TABLE_DISPLAY , as outlined in the documentation .

The ALV Grid keeps a reference to the table you passed to it during initialization. You update the contents of that original table and then tell the Grid to update itself.
