Evaluated Receipt Settlement (ERS) Voucher process - PeopleSoft Purchasing/Payables 9.2 pum 38

Hello, I've looked at both Payables and Purchasing PeopleBooks on the subject of ERS. It's my understanding that if one enables ERS, then by receiving an item via PO, a Voucher for what has been received will be created in Payables after running the Voucher Build process. I have not found any documentation that steps through both the configuration and the actual step by step process from Receiving the item in Purchasing, to the generation of the Voucher in Payables. Is there such a document? Thank you!
