The connection type with API name CT_MAY_CHG_PRIVIL is not available in Aris Connect when a model editing.

Here is a hypothesis:

Since you mentioned this connection type occurs in the privileges diagram, it might be that this method element is restricted for a particular licence type. The privileges diagram requires the UML Designer licence according to the method help: abs/help/en/method/#/home/HELPID_MT_WRKFLW_RGHT_MAN/en/1

So it may well be that the connection type is not available in Entire Method for modelling, if you do not have that licence.

Viewers in the portal can consume all modelled content.

M. Zschuckelt, 

Thank you for answering my question and your hypotheses! 

I checked them, but unfortunately, even with the UML Designer licence, the situation has not changed and the connections and The privileges diagram have not appeared in repository section ARIS Connect.
