Purchase Order Messages

Purchase order messages appear on the MRP/MPS Detail Message Revisions form with an order type of OP. You can process a purchase order message by using any of these methods:

  • Process a single action message without blanket order checking or consolidation.

  • Process one or more action messages with blanket order checking.

  • Process messages using purchase order consolidation to include more than one item on a purchase order.

  • Process purchase order messages by using a planning family.

  • Process messages using Oracle's JD Edwards EnterpriseOne Supplier Scheduling system.

    Note: If an item does not have a supplier assigned to it, the system displays an error message. Enter a supplier number and click OK.

To expedite message processing, it is recommended that you set up a different version of MRP/MPS Detail Message Revisions for each of the previous methods. That is, set up one version to process a single action message without blanket order checking or consolidation, another version to process one or more action messages with blanket order checking, and so on.

Depending on how you set the processing option for the MRP/MPS Requirements Planning program, the program creates either a purchase requisition (document type OR) or a purchase order (document type OP). The program includes a user ID on the purchase order and uses the system date as the date on which the purchase order was created.

In addition, the program creates the purchase order in the purchasing unit of measure, even though the action message displays the primary unit of measure. The program makes the appropriate unit of measure conversions. After the next DRP/MPS regeneration, the quantities that are associated with processed messages appear in the time series display on the +PO Quantity Type row.

When you process messages, the system firms that portion of the DRP/MPS replenishment plan. Subsequent DRP/MPS regeneration does not change the timing or quantities that are associated with previously processed messages. However, if the new regeneration finds a mismatch between the supply and demand quantities or dates, the program issues a message recommending that you realign the existing +POs.
