Calculate Geometry Attributes ArcPro 2.2

[AileenProfir]

Hi,

I'm trying to use the  'Calculate Geometry' tool (selected by right-clicking a field in the attribute table) to calculate XY coordinates for a point and have also tried to calculate square miles for a polygon feature. I am getting a "RuntimeError: Objects in this class cannot be updated outside an edit session".  It was my understanding that edit sessions are automatic in ArcPro.  How would I go about starting an edit session?

Thanks for your help,

Aileen

That did the trick for me.
