The best thing to do at this point is to run the analyzer. It will of course tell you that Branch Versioning is not set, but it should give clues as to why.
Some things to check when the Branch Versioning option is missing:
1. Make sure the fabric feature dataset was registered as versioned.
2. Is the geodatabase connection file set to Branch?
- Right click the .sde file and choose Geodatabase Connection Properties
- There should be an option for Branch versioning
- If this was the issue, check the option on and re-add your fabric to the map
3. The Validation or other layers and tables were not registered as versioned.
- Perhaps the parcel fabric is registered correctly but something else isn't.
- This could be the 3 validation layers and its associated table.
- Some other supporting layer that is outside of the feature dataset.
Run the analyzer and let us know what it reports. Thanks!
