Hello,
Is there any limitation for name of schema allowed to be used? I have PostGIS database, and when I make schema name be extremely short (less than 8?) i can see it from ArcGISPro'd catalogue. But longer schema name appears to hide contents in the schema.
I do not think there is a limitation on the schema name; Enterprise geodatabase size and name limits—Manage geodatabases in SQL Server | Documentation
I would guess that the ArcGIS Pro UI is making the table name available based on the UI size.
I would contact technical support and have an analyst take a look.
