trigger SAP Event

Hello Folks,

I've read many posts, but I don't find any solution.

The Problem is :

I' ve got an alv-grid on a tab-reiter application.

I can edit some cells within my grid. When I press 'Enter' after any change in the control, the data changes correctly, with the event "DATA_CHANGED_FINISHED".

in case that the changed cell composed from dropdwon list , it doesn't take the change itself into account and trigger immediately the event "DATA_CHANGED".

could someone let me know if he/she experienced with this situation ?

Thx 4 your help n ideas .
