How to pass parameter to search help
I have created a search help( zv_region) for a screen field(region) and assigned that search help( zv_region) to screen attributes of screen field (region). But i have two fields in my screen. These two fields i am not taking from table or structure. I declared in my module pool program as global fields.
I want to filter "region" based on "country". For example if they enter "US" in country field, then they click on search help for region field it needs to populate only all us states.
Please advice me how to do that.
Thanks in advance.
