Change requests - purchase ordersIf the change request functionality is implemented for purchase orders, a change request is required to update the purchase order and the related data. A change request is a copy of the original and actual purchase order (including all the related information) that is added to a new document and assigned a new document number. Change requests are required after the purchase order is approved, or after the order is printed (if the print activity is part of the order procedure). Only one open change request is applicable at a time for a purchase order. A new change request can be created only after a previous revision is processed or canceled. On a change request, you can modify the purchase order, order line, order line receipt, and the linked purchase order data, such as landed costs, material prices, and material supply lines. Activities that are part of the purchase order procedure, such as releasing the order to Warehousing, printing the order, generating supply lines, and invoicing the order, can be initiated only from the actual purchase order and not using the change request. For a purchase order, a change request can be manually created or can be generated based on the origins SFC, Sales, or Requisition. To modify purchase order data using the change request functionality: Step 1. In the Purchase Order Parameters (tdpur0100m400) session:
Step 2. Click Initiate Change Request in the Purchase Orders (tdpur4100m000) or Purchase Order (tdpur4100m900) sessions, to start the Purchase Order Change Request (tdpur4600m000) session. The status of the change request is set to Created. In case of change request generation, this step is executed automatically. Step 3. Modify the required purchase order data of the change request. Consequently, the change request status is set to Modified and the actual purchase order (data) is locked. Step 4. Submit the change request for approval (if ION Workflow approval is applicable). Step 5.
Step 6. Click Process Change Request to process the change request. Consequently, the change request status is set to Closed, the modified data is updated on the purchase order, the revision number is increased, and the purchase order is unlocked. An approved change request is automatically processed if the Process Purchase Order Change Requests Automatically check box is selected in the Purchase Order Parameters (tdpur0100m400) session. Field updates You can modify specific fields for a change request. The availability of fields on the change request depends on the status of the actual purchase order.
