Nested processes
Process 1
1.1 Call a process to do the multiple items processing
1.2 Call a process to act when all the multiples have completed
Process 1.1
FIND relevant BOs
1.1.1 Do the processing on the individual items
Process 1.2
Whatever you want to happen afterwards
If you have your decision tree mapped out correctly then the process 1 will drop down into process 1.1 find everything then loop through all of these BOs doing whatever processing is required in 1.2 (and any further lower levels required). Once the last BO has been processed then control will pass back to the top level process (1j and move onto 1.2
You could stage gate control process 1.2 from starting by making it conditional on something
For example
Process 1
CREATE TempBO with TempBO.Count =0
1.1 start process that receives TempBO
1.1.1 Find BO
1.1.2 start process that receives TempBO and FoundBO
1.1.2.1 Increment TempBO.Count=TempBO.Count+1
Process 1.2 can then be based on IF TempBO.Count>5 THEN start another process
