variable select option

[Andr2602]

Hello everyone, I would like to set up a variable selection screen in conjunction with a customizing table. There I have the respective fields and tables in separate columns. Is there a way that a select option variable can be created using this consultation and I can use the table to determine how many fields are then available?

Example table:
Field     Table 

ERDAT   VBAK 

Select Option would be 

ERDAT FOR vbak-erdat

Sorry, please clarify, I don't understand at all. Even with the example. What do you want to achieve?

Hi, we are on a s/4 system and we want to expand a selection screen in an enhancement for va05, but not hard rather dynamically, so that the customer enters the fields in a table, as I mentioned, and the select option is then built dynamically.

Table is like this: 

For line one I would expect:

SELECT-OPTIONS: erzet    FOR vbak-erzet

What you want to achieve is called "dynamic selection screen". You can only use the function modules FREE_SELECTIONS_INIT and FREE_SELECTIONS_DIALOG, i.e. one button in the selection-screen which runs the FM, which display a kind of selection screen with a dynamic list of fields. There are lots of examples in the Web, and there's the inline documentation of these FMs.
