BRF Plus - Domain values may not be unique

Hello everybody,

I have the following problem:

after months of proper functioning without error of our BRF Plus application, suddently, managing rules on BRF Plus, an error is risen, regarding some fields of different structures used in BRF Plus: "Domain values may not be unique", followed by "(see value table <name of the field> in DDIC)" .

This error is risen everytime I try to activate one of these structures or the Function that contains them in the signature.

I don't know what to do in order to solve this problem.

The SAP program that uses the BRF Plus in our system (dunning run) is not working anymore, due to these errors.

Thanks and regards.

Ermanno
