How to dynamically generate parameters based on dropdown?

Former Member — Wed, 02 Sep 2009 17:22:01 GMT

Hello,

newbie ABAPer question..

I was wondering if it's possible to dynamically create a UI based on the values on a drop list/drop down box?

For example, screen would initialize too

dropdown list filled with 1 - 50

field1 field2

user selects 10 from the drop down list, then the screen would look like this:

drop down list dropdown list filled with 1 - 50

field1 field2

field3 field4

field5 field6

field7 field8

field9 field10

field11 field12

field13 field14

field15 field16

field17 field18

field19 field20

thanks for looking!

Then you need to use fm

FREE_SELECTIONS_DIALOG

for dynamically generating the selection parameters screen.

Please make a search on this forum for sample code how to use this

If you don't have too many parameters, you may also declare all of them, and hide or show the ones you desire using LOOP AT SCREEN statement according to the entry selected in the dropdown listbox. This is simple and efficient. How many parameters do you have?
