Connecting processes to pools in BPMN collaboration diagrams
When you delete or move a process that is connected to
a pool in a BPMN collaboration model, the pool references an
unresolved process. You can reconnect the pool to an existing pool
or reference a new process.
Procedure
- In the diagram editor, click on a pool.
- In the Properties view, on the General page, click the Add icon
to create a new
process or click the Browse icon 
to connect to an existing process or to provide
the new path to a moved process.
