Let me describe my problem.
I have such an itab
data: begin of itab occurs 0,
chk(1) Type C,
matnr like mara matnr ,
maktx like makt-maktx,
end of itab.
I have made the field catalog of check box field appropriately.
wa_fieldcat-checkbox = 'X'.
wa_fieldcat-edit = 'X'.
but without making the layout-edit = 'X' THE CHECKBOXS are UNEDITABLE.
I can not click and change the state of the checkboxes.It only display the checkboxes but no click is available.
When the layout-edit = 'X' is given all the column is the grid are editable. and this is certainly is not what I want.
How can I remedy this problem ?
