List Box in GuiXTHow can I put a Code in a text field in an SAP transaction, with the user able to use a List Box to select the value? (Radio buttons are not feasible as there are far too many valid Codes.)

There are two possible solutions:

A: Define a local value help file. In addition to the right mouse click option to display the help file, you can put a suitable small icon behind the entry field that the user can click on to get the possible values. See>Documentation->Input Sets, @history notation:

Image ... input="Department:@History"

B: use the Viewer component as described in --> Tips&Tricks No. 16
