Oracle SOA Suite 11g PS 5 introduces BPEL with conditional correlation for aggregation scenarios by AMIS

Not too long ago, one of my customers had the following requirement: a file with invoice-entries has to be processed each night; for all invoice entries for the same customer, we would like to start a single BPEL process instance that aggregates the entries and creates a single invoice. To process the entire file, one BPEL process instance needs to be created for every unique customer who has invoice entries in that file. Note however that the Inbound File Adapter knows nothing about the customers or about previously started process instances, it will simply invoke a BPEL process ‘service’ for each line it processes.
The figure illustrates the situation. Note however that the invoice entries need not be sorted, and could well look like this. Read the article here.
