Hi,

in this cas u need to create one more internal table with the same data selected and need to compare the data from the table from ALV. Ex :



IT_MAT1[] = IT_MAT.

"in the USER_COMMAND routine use this

 DATA: GD_REPID LIKE SY-REPID,
  REF_GRID TYPE REF TO CL_GUI_ALV_GRID.
 
  DATA: L_VALID TYPE C.
 
*Code to reflect the changes done in the internal table
 
  IF REF_GRID IS INITIAL.
    CALL FUNCTION 'GET_GLOBALS_FROM_SLVC_FULLSCR'
      IMPORTING
        E_GRID = REF_GRID.
  ENDIF.
 
  IF NOT REF_GRID IS INITIAL.
 
    CALL METHOD REF_GRID->CHECK_CHANGED_DATA
      IMPORTING
        E_VALID = L_VALID.
 
  ENDIF.
 
LOOP AT IT_MAT."IT_MAT is the internal table from ALV

READ TABLE IT_MAT1 WITH KEY MATNR IT_MAT-MATNR.

IF SY-SUBRC = 0.

IF IT_MAT-MTAKL <> IT_MAT1-MTAKL.

"KEEP FLAG HERE ARE ANY MESSAGE

ENDIF.
. " Check for all fields and set the flag
.
.
ENDLOOP.

Hi,

If you want to make the whole ALV editable, call method set_ready_for_input of ALV class with parameter set to '1'

If you want to make some rows of the ALV editable->

In the example program BCALV_EDIT_2 there is a subroutine named fill_celltab. In this subroutine, the internal table attached to each row of the output table is filled which shows which fields of this row is editable. If you enter a row to this internal table without a fieldname, then the edit status of the entire row is affected.

Hope it helps.

Regards
