The Middleware is an established suite of products and processes used to quickly and efficiently integrate customers with all the bank's web-based global trade management systems.

        The Middleware is initiated to start the PO process, it will download the XML files received from Customers. The system will then run the PO Parser to read the PO's received from the customer's XML files. Initial business logic rules are applied to evaluate if the PO data is valid and needs to be processed. Based on the Business logic for processing POs, the Middleware will sort the POs and process each PO according to the status codes. The PO Process module will start to create, amend, split, delete or cancel the PO based on the PO Status Definition logic.
