@Praveen Kumar Akkala-Oracle Was there a document attached? I was not sure what you were referring to when you indicated "below document." Thanks for the clarification on this. Thanks, Walter

Thank you @Bhaskar Konar for the guidance on measures. I did make sure that both subject areas included measures. Unfortunately, that did not resolve the issue as I am still receiving the same error message. Still working to see if I can resolve this. Thanks again.

I am new to OTBI so am not sure what specific fields would be defined as a "measure." However, I am using fields from both subject areas and I only get an error when I attempt to use the supplier DFF from the GL journals subject area.

Thanks John @JohnW-Oracle! This is going to work for us.
