(Advanced Receiving users only)
Use Invoicing Sessions only if you received or expect to receive more than one invoice for a single purchase order. Invoicing Sessions allow you to split a single receiving document and pass off each invoice separately to A/P. You can have up to 999 Invoicing Sessions per receiving document. However, most vendors send a single invoice for a given purchase order. Therefore, most Epicor users will not use Invoicing Sessions, and may skip the topics in the Invoicing Sessions book.
If you do utilize Invoicing Sessions, your original receiving document in Modify Receiving Documents (MRV) is considered session 0, and each subsequent invoicing session you create receives a number, beginning with session number 1. It is assumed that if you create Invoicing Sessions, you are not going to make any changes to session 0, because its purpose will be to serve as your master list of all items on the receiving document.
Invoicing sessions allow you to not only designate the line items from a PO that you want to invoice, but also to designate specific quantities you want to invoice. For example, you may have only been invoiced for 6 out of the 16 units that you received of a particular item. In session 1, you would invoice the 6 units. Then later, when you receive another invoice for the remaining 10, you would invoice those in session 2.
