Trouble with predictive planning

Summary:

Hi all, I'm dabbling with predictive planning but running into a problem getting it to run on a simple form I have. I get "There was no historical data found for all members." error

Content (required):

My form is itself is organized this way:

POV: Version

Page: Lev 0 Entity

Column: Scenario (one), Year (FY20:FY23), Period (Jan:Dec)

Row: Base level account

• Suppression is turned on
• All rows have 2 1/2 years of test data
• I've been able to run "auto-predict" on the same source data set

What am I missing?
