This is an issue we’ve run into when upgrading several clients to eDOCS DM 10. This will also be a persistent issue for an eDOCS DM 16 upgrade and is something that your upgrade specialist needs to be aware of.
Back in the day of DOCS Open… when a new database was created, there were a number of defaults created in your Legal library. A Client/Matter and Document Type called “DEFAULT”, all three of those items being created with a SYSTEM_ID of 0 (zero). This wasn’t an issue as none of the items every referenced the other.
The introduction of Dynamic Views and Dynamic View security changed this. And the problem was compounded in eDOCS DM 10 as eDOCS moved to a true security inheritance model.
