Need help using method check_changed_data correctly

Former Member — Wed, 13 Dec 2006 18:44:53 GMT

I'm using method check_changed_data in my ALV program to update the grid with changes the user makes. The method works fine for this purpose. But I also want to know if any data actually changed. Can anyone give me an example?

FORM update_vendor .

do I need to call a different method before check_changed_data ?

call method gridhead->check_changed_data.

is there a parameter available here to see if anything actually
changed?

loop at gt_head into wa_head.

clear wa_head-lifnam.

select single name1 into wa_head-lifnam

from LFA1 where lifnr eq wa_head-lifnr.

if sy-subrc eq 0.

modify gt_head from wa_head.

endif.

endloop.

ENDFORM. " update_vendor

Hello Beth

If data have been changed then method <b>go_grid->CHECK_CHANGED_DATA</b> will raise event <b>DATA_CHANGED</b>. If you have an event handler method like HANDLE_DATA_CHANGED then you can, for example, validate the changes.

If no data were changed event DATA_CHANGED will not be raised and your event handler method will not be called.

Uwe
