Define different identification rule

Hello,

 

Under BusinessElement I add a new CIT "CustomCI" which inerite attributes from parent but where I want to define a new identification rule where "name" attribute" is not a key.

 

I try different solution, also by settings Key Attributes instead of Idenficiation rule, but the "name" is always required when I try to add a new instance for CustomCI.

 

It's like what ever I do, CustomCI inerite from BusinessElement the identification rule.

 

Is there a bug or a missing information like "we cannot define different key for child when parent have identification rule" ?

 

DataModel :

BusinessElement

      |-> CustomCI

 

Regards,

Steve
