We just enabled multi-site but need to be able to send only one invoice for multiple pack slips over the sites. In a thread for 2020 it said I would need a BPM and posting rule. I’ve done the posting rule, I am just trying to figure out where I need to go to start the BPM and will it require custom code? I know it has to me based on a method directive GetShipments but that’s as far as I have gotten.
