The main functionality of reservation runs is similar to the forecast runs defined on Create Reservation Run screen. But unlike a forecast run, a reservation does real reservations against the inventory. The inventory on-hand quantities and the BOM expected quantities are decreased by the reservation run. Furthermore, the Allocate Level options cannot be defined for a reservation run, because the inventory is the only basis for the material availability check.
A reservation run can be defined on the Create Reservation Run screen in the same way as a forecast run. For more information, see Forecast Run Setup.
Or, you create a reservation run based on a successfully completed forecast run on the Create Forecast Run screen.
Select the forecast run and click the Create RR button to create a reservation run.
This message appears when done.
Click OK, to close the message. Navigate to Forecast/Reservation Overview screen and click on the hyperlink of the Reservation Run, to view the Reservation Run header details in the Create Reservation Run screen.
As in Create Forecast Run screen, you can use the buttons to open Assigned Warehouses, Assigned Work Packages, and Run Limitations to check and change any of the settings copied from the forecast run.
If the reservation run definition is ok, click the Start button to launch the selected reservation run. The Job Scheduler box opens.
Click the Online button.
When the job runs successfully, RESERVED is shown in the Job Status field at the top.
You can click the View Online Log button to open Show Log File of Reservation Run window, which displays the contents of the log file created by the reservation run.
Similar to the forecast run, you can click on Reserved Nodes to open the Reserved Nodes screen, to check the result of the reservation run.
Here, you can check the status, quantities, weights, costs, and manhours calculated for the list nodes. In addition, you can use the Undo buttons as described in Forecast Run.
You can select a list node in the Included List Nodes block, and click on List Positions window to open the Reserved Positions screen.
Here, you can check the status and quantities calculated for the list positions, and in addition, you can use the Undo buttons as described in Forecast Run.
The Reserved Quantities column group displays the reserved quantities calculated by the RR.
Total On Hand Quantity - Total on-hand quantity to be used for manual reservations against the inventory. This field is for information only.
Total Reserved Quantity (actual+manual) - You can insert (at a maximum) the sum of Total On Hand Quantity + Actual Reserved Quantity. If you insert a total reserved quantity less than the actual reserved quantity, click the Process Quantity button to change the reservation run quantity and the reserved quantity on the list position. If you now insert a total reserved quantity higher than the actual reserved quantity, the difference is reserved as a manual reserved quantity.
Manually Reserved Quantity - Total manual reserved quantity; this field is for information only. If you want to reserve more material for this ident than calculated by the FR/RR, you can insert a total reserved quantity, which should be manually reserved from the inventory. When the Process Qty button is clicked, this quantity is reserved in the inventory and can be issued with MIR by Reservation in addition to the quantities reserved by the FR/RR for each list position. The manual reservation can be controlled on Manual Material Reservation and on Inventory History screens.
Actual Reserved Quantity - The quantity forecasted by the current forecast run. This quantity would have been reserved if the job was a reservation job. A forecast run does not reserve any material.
