Windchill 11.0 how to disable number field on rename EPMDocument screen?

[yxin]

We recently upgraded to Windchill 11.0 from Windchill 10.2. It seems like the new number field is always enabled on the rename EPMDocument screen. In Windchill 10.2, the following immutable constraint line in OIR can disable the number field, but in Windchill 11.0, the new number field is on with or without the line in OIR.

<AttrConstraint id="number" algorithm="com.ptc.core.rule.server.impl.GatherAttributeConstraints">
<Value algorithm="com.ptc.core.rule.server.impl.GetServerAssignedConstraint"/>
<Value algorithm="com.ptc.core.rule.server.impl.GetImmutableConstraint"/>
</AttrConstraint>

Do you have a case number or SPR number for this regression from PTC?

I did logged a call to PTC, but the tech support basically said it is behaving like this by design. I know how to modify modify the js file a little bit to disable the new number field, but of course that is not supported.
