Process Orders and POs

Hi all.

My company is migrating to P21. The implementation date isn’t until sometime mid 2024 but I’ve been given early access to training session and I’d like to get a head start.

Currently working on process orders and I’m confused. The Epicor self-help articles and videos haven’t been much use beyond basic aspects.

So far I’ve managed to create processes and pre-defined routing. Where I’m lost is the process PO portion. I did select “PO required” for the process but I can’t seem to find an option to actually create a Process PO. Is the function of generating a PO an automatic function of the pre-defined routing stage, or am I way off?

Is the pre-defined route the actual process by which material is converted (either internal or external)? Or is there a step after the pre-defined routing that needs to be completed in order to generate the PO and begin the flow of events?

Thanks, in advance, for any help.
