Relate sub-process to proper process

[El]

Let me explain my problem with a example.
Suppose I have 3 Process P1,P2 and P3.
One activity in P1 is sub-process and must calls P3. Same Scenario for P2, it means , there is a sub-Process Activity in P2 that calls P3.
How can I relate P3 to these activities?

Hi there,

I assume this relates to BPMN. There's a clue to the answer in your question - 'call'.

In the 'Properties' dialog for each 'sub-Process Activity' in P1 and P2:
1. set 'Type' to 'callProcessActivity'
2. that will enable a 'calledActivity' value, set it to P3.
