Select value from non related table

[marcobis]

Hi all, I have the table above: "Cod. Buyer" and "Cod. Forn." (CodFor in the model) are dimensions of the same table. "Rag.Soc." is a dimension from a non-related table with a column called COD_FORN equal to CodFor I tried

Only( {<COD_FORN=CodFor}>} RAG_SOC)

 but it did not work. Any suggestions?

[Or]

Perhaps:

Only( {<COD_FORN=p(CodFor)}>} RAG_SOC)

Thank you, but doesn't work.
