Understanding Production Controlled Items in a Receipt Route
You can monitor items from the moment that they leave a supplier's warehouse. The receipt route that you assign to an item determines the series of operations through which you process the item upon its receipt (for example, transit, staging, and stock).
The system enters an item into the first operation of the route upon receipt. You must transfer the item to subsequent operations in the route. You can remove (disposition) items from a receipt route.
When you transfer items to the last operation in a receipt route, the system updates the items to a received (on-hand) status.
You use the Receipt Routing Movement and Disposition program (P43250) to manage production controlled items in a receipt route.
MRP considers receipt routing quantities for production controlled items as on-hand inventory if the Receipt Routing Quantities processing options on the On Hand Data tab of the MRP/MPS Requirements Planning (R3482) and On Hand tab of the Master Planning Schedule - Multiple Plant (R3483) programs are set to 1.
The production number appears in the detail lines of the receipt routing on the Work With Routing Statuses and Receipt Routing Movement forms. You can search by production number using the QBE line on the Work With Routing Statuses form. Although you have visibility to the production number, you cannot change an existing production number or add a production number to a receipt routing.
You use the Receipts by Purchase Order (P4312) processing option on the Versions tab of the Receipt Routing Movement and Disposition program to specify the version that the system uses when you access the Receipts by Purchase Order program. You use the Receipts by Purchase Order program when you are moving items to an operation that is set up to move quantities into inventory.
You can set the Lot Number Override processing option on the Process tab of the PO Receipts program to override the lot number with the production number during receipts processing.
When receiving inventory on a receipt route detail line for production controlled items, the system updates the F41021 table to include the received quantity as on hand. The system does not update the F41021T table for production controlled items in a receipt route.
The last step in the receipt routing process is disposition, which moves production controlled inventory to an on-hand status and updates the F41021T table.
The system does not support a negative quantity for production controlled items on purchase order receipts. If you enter a negative quantity for production controlled items, the system enables you to select inventory to use from generic inventory and other production controlled items.
You consume the remaining required inventory using either blind or interactive mode.
You set the Production Number On Hand Consumption processing option in the PO Receipts program to blank to activate blind inventory consumption.
When the PO Receipts program is run to receive inventory blindly for production controlled items, the algorithm:
Allocates generic inventory.
Generic inventory is inventory for items that are not production controlled and, therefore, are not associated with a production number.
Allocates inactive production numbers.
These are production controlled items that have the Production Number Status set to I in the Production Number Master File table (F34401).
Allocates orphaned production numbers.
These are production controlled items that are no longer associated with a supply or demand.
Allocates production number by end item demand date.
This is the demand date of a production controlled item that is the farthest in the future. The system then replans the end item to meet the demand.
If you set the Production Number On Hand Consumption processing option to a value of 1 to interactively select inventory, then the system displays the Select Inventory for Consumption form. You select the specific inventory and quantity to consume.
You must complete the Secondary Quantity field if the item you are receiving is set up with dual units of measure in the item master record.
After you select the inventory to consume, you can access the Select Inventory to Consume form to review or redistribute inventory. You must have a value in the Move Quantity field to access the Prod No. Consumption option in the Row menu.
When receiving inventory for purchase order detail lines for production controlled items, the system updates the F41021 and F41021T tables. The F41021T table shows the on-hand quantity for production controlled items. The F41021T on-hand quantity increases if the purchase order receipt contained a production controlled item.
If the on-hand quantity in the F41021 is negative during purchase order receipts, then the receipt quantity of the production controlled item does not increase the on-hand quantity in the F41021T table. In this scenario, the system adds the receipt quantity of the production controlled item to the on-hand quantity in the F41021 table.
A reversal of production controlled inventory transactions increases or decreases the on-hand quantity of the production number used in the transactions.
The on-hand quantity for production controlled inventory in the F41021T table does not go negative. Therefore, if the on-hand quantity for the production controlled item is insufficient, then the F41021T table shows zero on-hand quantity and the F41021 table shows a negative on-hand quantity. All on-hand quantity for production controlled items must be consumed before the on-hand quantity of generic items goes negative.
You can manage production number inventory through the Production Number Workbench program before receiving purchase order lines.
