Correlation of Response in a Process via Queuing
I am building a custom application in Pega 7.3.1 where multiple processes (workflows) will be running at the same time. I have a step where each process sends a request to an external system and is waiting for a response via REST call. Once the response has been received, I have to correlate the response to the correct process based on a specific field (ex: SSN) so the process can move to the next step.
What is the best way to implement this?
Should we publish the message to a JMS queue so the process can subscribe to the queue? If yes, how do we implement this?

Hi,
How much time it will take to get response from the external service, based on this you can go with the Configure Connectors to Run In Parallel or Configure Connectors to Use Queued Execution.

Response could potentially come from external system after many days/months. Once the response comes, we need to correlate a key field in the response to correct process instance so that the appropriate process comes out of the wait condition and continues processing to next step.
