I have to guess what you did to get that far, and I'd strongly recommend not to continue along that road. What I'd rather do is

• create a new dictionary structure (not a transparent table!) that contains the screen fields you need
• use the TABLES statement with the structure to declare a global variable in your program or function pool top include
• place the fields of the structure on the screen, just like you did with the MARA fields in your example
• use the fields of your global variable in your coding

The way you prepared the screen, you would have to add a global variable named MARA with the structure of the transparent table MARA , probably using the statement TABLES mara. While this is perfectly possible, it's also really dangerous - you could end up changing the database contents inadvertedly, especially since you seem to be rather new to the system.
