variable select option

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
