Variables in screen painter

Question

Hi. I'm creating a SCREEN in screenpainter. I'm painting a Input/Output Field ang give it's name: EKKO-LIFNR. When I launch screen it works correctly (the corresponding records from DB appears after click on the field). But when I choose some value, how to refer to it in the code later? Greetings. P.

Answer 1

The steps I take when adding a field like this to a dynpro are:
1. Add the field and call it EKKO-EKORG.
2. When the popup asks you "The new name EKKO-EKORG is a field name from the ABAP Dictionary. / Do you want the screen element to refer to the Dictionary", confirm "Yes", and also "Yes" to "Dictionary field EKKO-EKORG / Do you want to copy field from Dictionary all attributes?"... this will bring through all the attributes such as conversion exits and parameter IDs.
3. Rename the field to the name you have defined in your code... typically in my programs this would be something like "GS_0200-EKORG" as I like to set up a structure for all fields on a screen (as it makes it quick to clear them, and document their use)... see step 5 below.
4. Change the settings on the "Poss. entries" if you want to force the Searchhelp icon to be forced on or off.
5. In the top include for the module pool define the variable e.g.
data:
  begin of gs_0200,   "named because g=Global, s=Structure, Dynpro = 0200
    ekorg                  like ekko-ekorg,
    field2                 like something-else, "etc etc
  end of gs_0200.
6. In your code you can refer to gs_0200-ekorg to pick up the value entered, or the value chosen from the picklist.
