Getting the error 12105 “No Transactions Found” when executing the AddOrder call.

Summary

Detailed Description

There can be several reasons for the error 12105 No Transactions Found.  One of the reasons can be the OrderStatus of related transactions and items that are not Active. If OrderStatus for the related transactions and items is Completed then the order is paid & completed and no other changes to the order can be made.

An order line item must meet the following basic requirements before it can be combined with other similarly qualified order line items into a Combined Invoice order:

1. The buyer and seller are the same for all order line items.

2. The same currency is used for all of the order line items.

3. When a Combined Invoice order is created, it is assigned a status of Active. In order for additional line items to be added to a Combined Invoice order, the Combined Invoice order must still be in the Active state. To determine the status of a Combined Invoice order issue a GetOrders call and examine the value returned in the OrderArray.Order.OrderStatus field.

4. None of the order line items are:
- A motor vehicle (Parts & Accessories categories are eligible)
- An item specified by the seller as an Immediate Payment item
- A real estate item
- An ad-format item (special non-auction, real estate advertisement listings)
