Hello
You can hide a field in ALV we need to DELETE _COLUMN method of the interface IF_SALV_WD_COLUMN_SETTINGS and pass the attribute name which needs to be hidden
lo_value->if_salv_wd_column_settings~delete_column( id = 'VBELN' ).
We need to paste the above code in WDDOINIT method of the view in which ALV is present
Using this we can hide the two fields which you need to hide in your case.
Points please if helpful
Regards
