I am trying to create a text field in ArcGIS Pro 3.0 attribute table with 3000 - 5000 characters. I save and it defaults back to 254.
How do I fix it?
As commented by @Erik:
Shapefiles allow only for field lengths of 255 characters. You need to use a different file type.
and by @Vince:
The hard limit on dBase III+ string length is 254, not 255, though it's not obvious why. Use file geodatabase, and your length won't change.
