Model errors:
MVH201 Derivation expression specified for non-derived attribute (Issue.Job) [Issue.Job]
I'm wondering if this was intended to be MVH201 Derivation expression specified for non-derived attribute
("class.attribute") ["Derivation expression"]
If you at first had the attribute as derived - and then in a subclass added an override for it (derivation expressions on the subclass) - but then made the original attribute persistent again (none derived) -> bam!
MDriven will warn you that the derivation expression in the subclass is there - but it has no effect.
