A Cart Failed to Import, So I Entered the Order Directly in the ERP System

In some cases, your ERP system will reject a cart on import, so the cart will get stuck with a status of ABORTED, PENDING, or PROCESSING. The cart can usually be fixed and reset, so that the ERP system will accept it. However, if you manually enter the order in the ERP system, you should then close the ABORTED cart.

Once the cart has been entered into the ERP system, obtain the ERP Order Number

Go to the "Order Details" page for the cart.  Enter the ERP Order number in the appropriate box (1) and click "Close Cart" (2).

Enter the P21 Order number in the appropriate box (1) and click Close Cart (2).

This associates the cart with the proper ERP order number. It also will set the cart to "PROCESSED", so that it will be removed from the "Recent Carts" section of the Admin Home Page after 24 hours.
