Hi,
<b>To modify database or ztable from the ALV grid,you need to do the following:</b>
---You have to modify the field Catalog fields (fields that you want to make editable).Set the field <b>EDIT as 'X'</b>.For example if you want to make the field below editable:
ls_fcat-fieldname = 'CARRID'.
ls_fcat-edit = 'X'.
APPEND ls_fcat TO pt_fieldcat.
---Call the method below before you call the set_table_for_first_display.
CALL METHOD ALV_GRID_INSTANCE-><b>set_ready_for_input</b>
EXPORTING
i_ready_for_input = 0. ( For Display ) and ('1' for Edit )
After this put the set_table_for_first_display.
<b>Now if the ALV data has changed,and you want to change the database or ztable,then in your pf status give a function code for SAVE button in the GUI.
In the PAI of the screen,in user command module write the following:</b>
WHEN 'SAVE'.
<b>call method gr_alvgrid->check_changed_data</b>
importing e_valid = l_valid.
if l_valid = 'X'.
<b>MODIFY spfli FROM TABLE itab_spfli.</b>
endif.
<b>(l_valid is a flag.</b>
DATA:l_valid type c.
If you want to check if the user has entered any value on the grid, use the Method : CALL METHOD gr_alvgrid->check_changed_data.
This method returns a flag l_valid which can be checked to see if the data on the ALV grid has been changed or not.)
