F4 Help in ALV Grid (using CL_GUI_ALV_GRID)

Hi Friends,

I have created a report which has a ALV Grid control. In the output one of the column X (from Z table) is editable and should have F4 help. Data element of X column has a searchhelp attached with. While creating Fieldcatlog set the ref_field & ref_table columns.

When I press F4 button column X on grid, I'm able to get Popup and able to select value among the list. But the value whatever selected should be moved (in DATA_CHANGED event) to the internal table which is base for report output. But for the same if I remove F4 then the value is being moved to internal table.

Why system is behaving like this for F4 fields? How to move value selected in F4 field to internal table? If anyone knows answer, please reply..

Regards

Jaker.
