I have to enhance a program written by a colleague: It is an editable tree control where we can change some checkboxes. The tree control is inherited from CL_GUI_ALV_TREE. It has an additional method HANDLE_CHECKBOX_CHANGE.
I want to add an editable character field. I extended the structures, made change to field catalog but the field is not editable.
Any idea as how to proceed?
Thanks in Advance,
