What's the difference between the processing of returns for a regular receipt and a back-to-back receipt?

The processing is similar in that there is no difference in the returns handling of a transfer order receipt. However, when creating a return transaction against a receipt for a back-to-back purchase order, there is a difference in the processing of the reservation.

When handling returns for a back-to-back purchase order, the application attempts to maintain the reservation. When the receipt was initially put away, the supply side of the reservation would have automatically moved from the purchase order to the new on-hand quantity for the quantity put away. When creating a return transaction for this quantity, the application automatically attempts to maintain that reservation by moving the returned quantity back from the on-hand supply to the new open purchase order supply.

The application performs this action as long as there are no downstream actions against the reservation that change the reservation. For example, situations that can prohibit this automatic action include:

• Manually changing the reservation using the Reservations and Picks page, such as: changing quantities, assigning subinventories and locators to the reservation, and changing the demand side of the reservation (changing the sales order)

• Initiating the shipping processes to assign picks against the sales order
