Backflushing Lot Material for Job Operations

Use the Backflush Lots form to issue backflush lot material to job operations. While working on an operation and reporting quantities, user must access the Backflush Lots form by selecting Backflush Lots on the parent transaction form if there are any BOM item that is lot-controlled and designated for backflushing. The Backflush Lots form can be accessed from the End Run, Job Move, End Just-in-Time, and End Production Schedule transactions.

Reversing the Quantity: The Backflush Lots form displays the list of lot numbers issued to the current BOM item and allow users to accept positive quantity for the inventory. The quantity logic would work like the way it is working in a positive move transaction except the negative OnHand check, since this is an inventory inbound transaction.

To reduce the keystrokes and increase the user experience, the Lot (Row) Selection check box is defaulted with a calculated value for the selected Quantity (Sel Qty) field. The calculation logic looks for the on-hand quantity and compare with the remaining target quantity and default the value whichever is less. This allows the user to specify the quantities to be backflushed. However, user can overwrite and manually update the quantity.
