If a requisition contains two line items for two different suppliers, and one line item is pushed to the ERP but the other one fails, only the pushed line item is added to an order. However, if both lines are intended for the same supplier (and order), the order isn't created until the problem is resolved and both line items are successfully pushed to the ERP.

If any of the requisition's related orders fail to push to the ERP system, Ariba Buyer displays an error in the Comments section of the Request Details screen; expand the comment for failure details. To see which orders were pushed successfully, view the previous version of the requisition on the History tab.

When an order is changed or canceled, the corresponding orders in the ERPs are also changed or canceled. Therefore, when you change or cancel orders using Ariba Buyer, do not change or cancel them manually in the ERPs. In addition, for best results, do not receive orders using the ERPs; receive them using Ariba Buyer.

When a requisition is fully approved, your company can “push” the related orders to an Enterprise Resource Planning (ERP) system (such as Oracle), where the orders are sent to suppliers.

Occasionally a problem can occur during the process that prevents one or more orders from being pushed to the ERP. For example, the ERP system might not recognize the value for a certain field, such as a unit of measure. When an ERP push fails, the following events can occur:

• The requester or an authorized user, such as a purchasing agent, receives an email notification message that describes the failure. For example:
  • If you change a requisition by deleting all of the line items from an order (essentially canceling the order) that was pushed to your ERP system and canceling orders is not enabled for your ERP, Notification 35 is emailed to authorized users, typically purchasing agents. The purchasing agent must undo the deletion of at least one of the line items, ensuring the order is not canceled and a change order is sent.
  • If changing orders is disabled for your ERP after you have created a change order but before the change order has been pushed to the ERP, Notification 58 is emailed to authorized users, typically purchasing agents, who must then cancel the change order.

  Contact your Ariba Buyer system administrator as necessary to resolve the failure.

• Depending on how push failures are handled, an order can revert to its previous status (Canceling for cancel orders or Ordering for change orders), or the requisition status reverts to Composing.
• The History tab is updated and indicates the status change and ERP push failure.
• The requisition is updated with the ERP order number for line items that were successfully pushed to the ERP. To see the order number, view the requisition details on the Request Details screen and click the Orders tab. The order number is listed in the ERP Order ID column. Line items that have been pushed can no longer be changed or deleted.
