ArcGIS Pro 2.3.2 not saving domain changes for subtype fields, even though I am the owner of the database and the domains are in the database.
I have the same issue whether I am in FGDB or SQL Enterprise DB.
Example (FGDB) -
When I try to add the existing domain 'UoM' (units of measure) to the UoM field for piping devices, I am able to select the domain and it stays for all of the subtype options for that field. (Attachment Domain1)
As soon as I save, the data disappears and I get the red bar in front of the first subtype and the error code 999999 (Attachment Domain2)
This is repeatable - I have rebooted, saved, closed the app, anything I can think of to clear the 'cache', but to no avail!
Thank you,
Melodee
Not that it helps you but this is one of the major reasons why we abandoned subtypes a number of years ago.
In ArcMap you sometimes had to individually assign the domain to each subtype.
Pro is set up much nicer for managing subtypes.
Issues I can speculate on is you may need to unregister as versioned. Stop all services running on the feature. Remove any Relationships that may exist
