Data_changed event not capturing changed data on ALV grid after F4

[Former Member]

Hi All,

I have handled the F4 event on an ALV grid. The values are copied back correctly to the grid. But the changed values are not

being captured at all in the event Changed_data.

When I enter the values manually, by typing, the values are getting captured. I have handled all the required stuff like, set handler for event, registering the evt_modified, registering the fields for F4.

Any clue on if I am missing anything here.

Thanks a lot in advance for the inputs.

Regards.

Hi,

Please check calling the method CHECK_CHANGED_DATA of grid in the PAI of the screen.

Try it before CHECK_CHANGED_DATA.

ls_stable-row  = 'X'.

ls_stable-col  = 'X'.

l_soft_refresh = space.

call method Grid->refresh_table_display

       exporting

         is_stable      = ls_stable

         i_soft_refresh = l_soft_refresh.

Hi all,

I have already put in all these stuff and it did work.

Made this work with a workaround.

Thanks & regards,

IN GRID YOU HAVE TO PASS THE I_APPL_EVENTS = 'X'.

THEN IT WILL WORK AFTER YOU DID ABOVE STUFF.
