Backflush Calculation Methods
Specify one of two backflush methods for the base process in Co/
By-Product Maintenance (15.12.1) or Process/Formula Maintenance
(15.18). The backflush quantity for the base process is used to calculate
backflush (issue) quantities for the components of a joint order set.
In Work Order Receipt Backflush (16.12):
Work Order. Enter any work order number in the joint order set.
ID. Enter the specific ID desired, or leave blank to retrieve the first ID
in the joint order set.
Receive All Co/By-Products. Enter Yes if all co-products and
by-products are to be received. Enter No if only the items on this
particular order are to be received.
Backflush Method. Enter 1 or 2. Method 1 backflushes based on the
co- and by-product quantities received. Method 2 backflushes based
on the order quantity of the base process. The following two sections
describe each method in more detail.
Backflush Method 1
The backflush (base process) quantity is calculated from the receipt
quantities processed for all the co-products and by-products. Unit of
measure conversion factors are used to express all item quantities in base
process units.
Use Method 1 when the quantity for a batch is directly related to the sum
of its output. For example, for a process that sorts fruit into different sizes
and grades, the batch quantity can be calculated from the total amount of
fruit processed for all sizes and grades. This method is generally used
when there is greater variability in output percentages for products.
Backflush Method 2
The default backflush (base process) quantity is the order quantity for the
base process work order. You can change the backflush quantity to reflect
the actual quantity processed for a batch.
