Backflushing Lot Material for Job Operations

Use this form to issue backflush lot material to job operations. While working on an operation and reporting quantities, click Backflush Lots on the parent transaction form if any BOM item exists that is lot-controlled and designated for backflushing.

You can access the Backflush Lots form using the Backflush Lots option in these forms:
  • End Run
  • Job Move
  • End Just-in-Time
  • End Production Schedule

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 On Hand 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.

  1. Click Backflush Lots form on the parent transaction form.
  2. Select an operation in the Backflush Item section for which material must be backflushed. This information is displayed for each operation:
    • Operation number
    • Item number and description
    • Target Qty: quantity required
    • Selected Qty: quantity currently being backflushed for the operation
  3. Select one or more lots in the Backflush Item Inventory section from which material must be backflushed. This information is displayed for each lot:
    • Lot number
    • Unit of measure
    • On hand quantity
  4. Specify the quantity to be backflushed in the Selected Qty field for each selected lot. You must backflush a total quantity that matches the backflush quantity of the operation.
  5. Click Assign. The material from the selected lots is backflushed to the selected operation.
    Optionally, follow the steps above to assign material to another operation.
  6. Click the green process button.
