Process Flow for Receiving
When you receive a product, a receipt is generated as proof that the product arrived. The following figure shows the process flow for receiving.

The process flow for receiving includes the following steps:
If the order is unidentified, then generate an unknown receipt.
If the order is identified (Internal Order, Purchase Order, Repair Order, or Return Material Authorization), then create a receipt.
Generate the transactions.
The necessary inventory transactions are created, and the necessary line item actions on received orders are created.
