Cannot Order Table Error Message

Thanks for your replies. Here is what I did to resolve.

Error Message Numbers

Those numbers in the error message are the id's for the table and columns respectively.
I translated those id's to names by using INFO.VIEW

INFO.VIEW.TABLES()
INFO.VIEW.COLUMNS()

Using this I was able to narrow down that the problem was my Date Table and specifically MonthName_1 (A single character for the Month Name) and the Sort Column " Sort Year Month"

I entereed the DAX for the Calculated Column in Google Gemini. Gemini recommended a few changew which I tried. No Improvement - still get an error message. 4-5 rounds of this, always an error message.

Gemini finally recommended a complete refresh and rename the the single character column to something else. The cache is stuck.

That solved it.

Lessons:

1. If you get a handful of id's that do not make sense, translate them to the table names and column names

2. Refresh and change names of columns - the cache is stuck.

Thanks
