The Backflush Confirmation screen is displayed after entering a shop order receipt transaction and backflush materials are located on the shop order bill-of-material or backflush labor operations are present on the shop order route. The header information on the screen summarizes the shop order header information and provides a reference to the shop order receipt quantity that was entered on the Inventory Transaction Reporting screen. The two lower sections of the screen present the material and labor backflush lines separately. Either one of these sections may not be displayed in the event that backflush materials or operations do not exist on the shop order. The backflush quantities can be modified in each section before clicking the Accept button to process the transactions.

A material backflush refers to a special type of material issue to a shop order. Normally, materials are issued to a shop order one item at a time based on actual usage. The actual usage can then be compared to the standard quantity required to determine material variances. However, single-issue transactions can be time-intensive and may not be necessary for low-cost, high-volume items where the variance is negligible. In these situations, a backflush transaction can save time, but still capture the usage of material on a shop order.

A material backflush transaction issues material to a shop order automatically when a shop order receipt is entered. The issue quantity is based on the quantity required for the shop order component and the quantity received of the shop order parent item. For instance, if a shop order for 100 printed circuit board requires 200 transistors, a shop order receipt for 50 printed circuit boards would prompt a backflush of 100 transistors if the transistor was marked as a backflush item on the shop order bill-of-material.

A labor backflush can be entered for an operation on a shop order route in the same manner that a material backflush is entered for a bill-of-material item. The labor backflush occurs in lieu of reporting labor hours for the operation and is entered automatically at the time of shop order receipt. Labor backflush is typically appropriate in situations where cycle times are short. The ability to modify the backflush labor hours during Backflush Confirmation allows labor variances to be properly reported and reconciled.

A labor backflush transaction reports hours completed for a shop order operation at the time of shop order receipt. The setup and/or labor hours reported depends on the hours required for the shop order operation and the quantity received of the shop order parent item. For instance, if a shop order for 100 printed circuit board requires 20 hours at the surface mount operation, a shop order receipt for 50 printed circuit boards would backflush 10 hours of operation run time for the surface mount operation. If the operation required setup, the setup hours would also be backflushed.
