Save Plans

The system enables you to make changes to the current MRP in the Supply/Demand Details grid and then save the changes to the plan. You change the quantity or date for a message by using the Adjusted Quantity and Adjusted Date fields in the Supply/Demand Details grid. When you click the Save Plan button, the system updates existing messages and adds new messages to the F3411 table.

The system applies the following changes when you save the plan:

• If you change the adjusted date for a record with only an Increase Order Quantity to message, then the system adds a new Defer or Expedite message to the F3411 table.

• If you change the adjusted quantity for a record with only a Defer message, then the system adds a new Increase Order Quantity to or Decrease Order Quantity to message to the F3411 table.

• If you change the adjusted quantity increase to the original quantity, or the deferred date to the original date for a record with Increase Order Quantity to and Defer messages, the system updates the message quantity and date in the F3411 table.

  Although you changed the quantity and date back to the original quantity and date, the system does not delete the F3411 message. Deleting the message can make the change invalid if older messages exist for the same order.

• If you change the quantity to be less than the original quantity for a record with an Increase Order Quantity to message, then the system updates the quantity and message type of the F3411 record. The system performs the same processing for Decrease Order Quantity to, Defer, and Expedite messages.

• If you add a B type message, then the start date becomes today's date.

• If you change the request date to a past date, then the system retains the message type as B. The system creates an Order & Expedite message if the date is within the lead time level.

• If you create a B type message for an order where the request date falls before the lead time, the system retains the request date and enters a start date equal to the start date on the Planning Console form.

• If you modify the request date to a future date, the system changes the message type to O and updates the F3411 record.

• If the request date is greater than or equal to the lead time, then the system updates the O message.

• If the system adds an O type message and you modify the request date to a future date, the system updates the date field in the F3411 table.

• If you modify the request date to today's date for an O type message, then the system updates the message to a B type.

• If you change the date to a past date for O type message, then the system modifies the message to a B type.

• If MRP generates a Cancel message for an existing work order, then the system updates the Adjusted Quantity field to a value of 0.

• If you modify the quantity and defer the date on a work order, then the system adds a new Increase Order Quantity to or Decrease Order Quantity to message and adds a new Defer or Expedite message, depending on the messages in the F3411 table.

For production-controlled items, you can change the production number in any of the messages and the system updates the production number on the order. The system validates that the item is production-controlled and that the production number exists in the Production Number Master File (F34401) table.
