Using recursivity in ALV list to handle data changed


Hi folks

I am trying to use a kind of recursivity to handle ALV data changed.

The method HANDLE_DATA_CHANGED is triggered whenever I change a certain cell and press Enter.

Inside this method, I want to force the content of another cell to be changed and want this method HANDLE_DATA_CHANGED to be called recursively, so that the same logic fills the rest of the line as it does when I really modify the 1st cell.

The logic of HANDLE_DATA_CHANGED starts with a loop on lt_mod_cells. lt_mod_cells is filled the following way:

lt_mod_cells = er_data_changed->mt_mod_cells, where er_data_changed is an instance of CL_ALV_CHANGED_DATA_PROTOCOL.

If I simply add a line to lt_mod_cells, I get a short dump because inside method HANDLE_DATA_CHANGED there is a call to


And inside the instance er_data_changed, there is only the relevant information about the cell I manually changed in the frontend, but nothing related to the cell I added via ABAP to lt_mod_cells.

And by the way, it doesn't seem very trivial to manually fill all the necessary tables inside instance er_data_changed, so that my manually added line gets properly changed.

Any suggestions??
