Icon_enter_more

Dear All The ABAP Gurus,

I am developing a module pool in which I have displayed a pushbutton for entering more values and having ICON_ENTER_MORE

as icon. Now I want that when user clicks the pushbutton then the Pop up should get open as we get in Select-options or Parameters with no interval in Reports. I dont want to write a report and use call screen. The field in which I want is Profit center so that user can enter multuple values in it. it is not used as from-to .

How to get the pop up and read the entered values in internal table so that data can be brought based on the multiple profit centers entered.

Thanks In Advance,
