Auszug aus der Doku, damit sollte eigentlich klar sein, was du einstellen musst:
You can use Generic Relationship Management (GRM) rules to limit what objects can be pasted to other objects. For example, if you do not want a certain type of object to have a specification relation to another type, you can set the cardinality to 0 to deny pasting of one type of object to another with the specification relation.
For an example of creating a GRM rule, see Workshop 9: Add a relationship rule. For reference information about GRM rules, see GRM rules reference.
When you create the GRM rule, the following constraints must be defined:
Determines the number of allowed occurrences of the primary object in relation to the secondary object, and of the secondary object in relation to the primary object.
When you create a GRM rule, type a number in the Primary Cardinality or Secondary Cardinality boxes:
-1 or *
Allow an unlimited number of relationships.
Do now allow any relationships.
1, or 2, or 3, and so on
Allow the specified number of relationships.
Specifies whether the relationship links between objects can be added, deleted, or otherwise changed.
Specifies whether new relationship links can be made between objects.
Specifies whether the relationship links that exist between objects can be removed.
