Can you write data from the "Usage Data" object back to an MDA table for calculations?
We need to perform simple calculations ((X + Y * Z) * 100) on data that is stored in the Usage Data object. We've been able to use calculated fields in the rules engine to write short-term and long-term moving averages back to the Usage Data object, but no matter what we try we cannot write those same values to an MDA table (where we need it to perform additional calculations on). Is there some limitation we need to be aware of, and more importantly a way to do what we need?
