AWS Marketplace gives you the option to add purchase order numbers when subscribing to SaaS contracts. If you add a purchase order number that matches with one of the existing purchase order IDs in AWS Purchase Order Management console, then AWS will create a new line item type called “AWS Marketplace Transaction” under the same purchase order ID. A “purchase order number” in AWS Marketplace is synonymous with “purchase order ID”. For example, if you have an existing purchase order ID “1234” in AWS Purchase Order Management console and enter purchase order number “1234” in AWS Marketplace, a new line item type “AWS Marketplace Transaction” will be automatically created under “1234” in AWS Purchase Order Management console. However, if you are entering a new purchase order number in AWS Marketplace that does not match with a purchase order ID, AWS will create a new purchase order ID in the AWS Purchase Order Management Console. For example, if you enter “poc1” as the “purchase order number” in AWS marketplace and if it does not match with an existing purchase order ID, AWS will create a new purchase order ID “poc1”.
