DB lookup using DFKKOP table in BRFplus

Hi Experts,

I'm trying to create a DB lookup with in a BRFplus application, the problem I'm getting is that when I use table DFKKOP I get a reference error. I do not see any place in the table definition where I can reference the amount field (BERTH, BETR2, BETR3, SBETH, SBET2, SBET3, SCTAX).

I have created within the application the form the structures for tables X001 and T001 (WAERS), which are references in DFKKOP but this does not fixed the problem.

Thanks
