Copy ED or drag and drop between Engineering models - issues in copying items with subscriptions for user with limited permissions

[MartinFijneman]

TBD what expected or wanted implementation behaviour is, noticed unwanted issue for participant with limited permissions (typical domain expert) for the following situation/ steps:

• setup a new Element Definition X with several parameters owned by domain A, with participant A
• copy the ED or create additional ED Y and set subscriptions for several parameters

If the participant has a domain expert role with permissions on parameters subscriptions modify_if_owner, the following situation occurs:

• for copying action of the EDs:
  ** ED X can be copied by the domain expert
  ** ED Y cannot be copied, gives an error: An error occured when deleting a copy of an Element Definition
• for drag and drop to another engineering model:
  ** using no keys, the action is allowed for both EDs, so X as well as Y, where in the copy of ED Y the subscriptions are taken along (so created)
  ** using "cntrl" to keep ownership of items (which should in principle make no difference in expected result), the action is not performed, gives error message: The CDP4 Services replied with code Unauthorized: Unauthorized: "exception:The person testde2 does not have an appropriate create permission for ParameterSubscription."

This situation is a bit confusing and unwanted, where:

• for copying: an owning domain is not able to copy one of its own items, if other domains have subscriptions on the parameters
• for drag and drop: was expecting to get the same result without any keys or when using "cntrl"

There is a workaround for this issue, in setting the permission on Parameter Subscriptions to "Modify" for domain experts (where there is not really a possibility for a domain expert who is assigned to domain A to actually change subscriptions on behalf of other domains.

Info:
noticed issue when testing version 10.0.4.2, on dev server with version 10.0.0
