Receiving, Scrapping, and Backflushing
To receive and scrap co-product and by-products in a joint order set, use Work Order Receipt (16.11), Work Order Receipt Backflush (16.12), or Work Order Operation Backflush (16.19). You can initiate these programs using any work order in a joint order set.
In Work Order Receipt (16.11):
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 this particular order is to be received. This prompt only applies if the order being received is not for the base process. When the base process order is received, all related work orders are received by default.
Use Work Order Receipt Backflush (16.12) and Work Order Operation Backflush (16.19) to:
Modify the backflush quantity and method.
Initiate transactions to receive co-products and by-products.
Backflush (issue) base process components. When components are backflushed, the receipt and scrapped quantities are used to calculate default issue quantities for the components.
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-product 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.
Use Method 2 when the batch quantity is closely related to the expected output of a particular co-product. For example, for a process that makes ice cream, the batch quantity can be calculated from the amount of ice cream processed. Any by-products, such as waste water, are not necessary for the calculation of the batch quantity.
Receiving Unexpected Items
Occasionally, an item produced from a joint order has a different grade or quality than expected. When this is the case, and the item assumes a different item number than the expected item, it can be received even without a joint order in the set for the unexpected item. These items are received as substitutes. A new order with a quantity of zero is added to the joint set.
Regulatory Attributes Control (1.22.24) setting for Modify Co/By-Product Receipts determines what items can be received by:
Work Order Receipt (16.11)
Work Order Receipt Backflush (16.12)
Work Order Operation Backflush (16.19)
When an item does not have a joint order in the joint order set being processed:
Yes enables a receipt to be processed for any item number, even if it is not defined as a co-product or by-product of the base process.
No enables you to receive only the expected items or valid substitute items. Valid substitute items are defined in Item Substitution Maintenance (13.19).
When a substitute item is received instead of an expected one, change the status of the joint set to Closed shortly after recording the receipt. The order and open quantities for the expected item remain unchanged when another item is received as an unplanned receipt. Closing the joint order set effectively changes the open or expected quantities for all items to zero.
See Setting Up Definitions for Valid Substitute Items.
