Hi All,
I have a blended datafile from about 10 sources, resulting in some data that has info to year 2020, but most data being more sparce. I want to use generate rows to create rows up to 2020. Seems simple.

I have used Summarize to add a Max_Year field and have looked at all the examples. I continue to get errors I don't understand. "Value did not change after the loop expression. Thanks for your help!
