Hi Paul,
when attempting to drop AssetGroup "Bond Junction" from WaterJunction feature class - The error message says it is "in use by another domain or subtype"
The deletion is happening against the Utility Network itself not the package.
The workflow we are attempting to use is
- stage and create the UN in our ArcGIS Enterprise geodb from the starter WaterDistribution_AssetPackage (without loading the data)
- change the coordinate system to match our needs
- disable the UN
- modify the schema of the classes in the UN to match our data requirements
- update the rules and associations to match the new schema
- re-enable UN
- export as a new local package
- use the fgdb in the package as a template for a staging file database
- use FME and simple loader tools to populate the staging fgdb
- load the Enterprise GeoDB from the staging fgdb
- enable branch versioning, etc...
