Connection Name (Reference) – Only in Multiproject
If you create a connection to a partner in another project, that has not yet been
merged with the current multiproject, you must enter a connection name as
reference. Interproject connections can then be joined up based on this reference.
As soon as the connections have been brought together, the connection name
(reference) can no longer be entered.
