Overview
Labor Backflush is the function that allows the system to add Labor Hours and costs to a Work Order automatically. These are added based on the time standards set on the part’s routing and quantities reported complete times the selected hourly rate. Backflushing labor is commonly used to eliminate the need to enter Labor transactions manually. Reported completions at Operations designated as ‘Labor Backflush’ Operations trigger the system to add Labor Hours as mentioned below:
-
For Work Order Operations, other than the last operation, the system adds Labor Hours upon completion of that Operation.
-
For the last Work Order Operation, as the system completes the Operation during the Work Order Receipt transaction, the user cannot manually book Time and Quantity for this Operation. The system adds Labor Hours during the Work Order Receipt transaction.
Application
This functionality is often used in highly repetitive manufacturing where the actual manufacturing time varies little from the standard. It is also used by manufacturing companies where labor is a very small component of overall manufacturing cost.
Prerequisite
Labor Backflush Feature must be Active at the Division level.
Set flag 'Cost Backflushed Labor at LG Standard' on Division record, MISC section, to True if labor should be backflushed at the STANDARD rate for the operation instead of the user hourly rate.
1. Processing – Routing Operation
NOTE These instructions will adjust all future Work Orders using this routing to have labor backflushed at the designated operations. Instructions to backflush a single Work Order follow.
Navigation
Routing Master > Routing Operations > Options Tab
Step 1 - Check the box for ‘Backflush Labor at Qty Complete’.
Step 2 - Set the 'Labor Backflush Txn Usr' to the Manufacturing User to be associated with the labor transaction. Do this ONLY if a single user rate should be used for all labor transactions for this operation rather than using the Manufacturing User rate that is reporting the completions.
Fields
Backflush Labor at Qty Complete: If checked, when a Qty Complete booking is made, a labor transaction will occur. If the labor type on the routing is Per Piece, it will use the Std Hours x Qty Complete x Rate. If Per Batch, it will use a prorated labor amount (Std Hours/WO Qty) x Qty Complete x Rate.
Labor Backflush Txn User: If Backflush Labor at Qty Complete is checked, when a Manufacturing User is specified here, the specified user & Employee Rate will be used on the "backflush" labor transaction. If left blank, the transaction will use the login user and their Employee Rate.
2. Processing – Single Work Order Operation
Operations may also be set to backflush labor on specific Work Orders. The following steps will set individual Work Order Operations to backflush labor but will not affect other work orders for the same part.
Navigation
Routing Operation > Qty Reporting Options Tab
Step 1 - Check the checkbox for ‘Backflush Labor at Qty Complete’.
Step 2 - Set the 'Labor Backflush Txn Usr' to the Manufacturing User to be associated with the labor transaction.
Fields
Backflush Labor at Qty Complete: If checked, when a Qty Complete booking is made, a labor transaction will occur. If the labor type on the routing is Per Piece, it will use the Std Hours x Qty Complete x User Hourly Rate (or other hourly rate depending on setup flags). If Per Batch, it will use a prorated labor amount (Std Hours/batch) x User Hourly Rate.
Labor Backflush Txn User: If Backflush Labor at Qty Complete is checked, when a Manufacturing User is specified here, the specified user & Employee Rate will be used on the "backflush" labor transaction. If left blank, the transaction will use the login user and their Employee Rate.
