Why I am allowed to define two parents of an Artifact in RRC

Why I am allowed to define two parents of an Artifact. I would expect to be restricted like in RTC to one parent

The definition is:
Decomposition Parent Of / Child Of (System-defined) Captures part-whole relationships between Requirements Management artifacts. These types of links are typically used to represent artifact hierarchies.

If I allow multiple parent,  I allow people to build a meshed net and not really a hierarchy.

Did I miss something. A special setup?

Thanks

The link type system in RRC does not have process definition to control when or who can create link types between artifact. Only a preference on the defaults.

That said in Requirements it is possible that the requirement has multiple parents, for example I am product of both a male and female, or I am both Human and a Citizen of a country, or a Car has 4 wheels, so do other vehicles.

So once process control becomes part of the solution you will be able to automatically control link creation, until then it is a manual process.

Hi Robin.

Understood. But I have to admit that I don't like the name of this decomposition links.
Specially when you are using RTC this is puzzling.

Thanks
