To allow category data to flow from Datapel's Warehouse Management System (WMS), through the Connector and into a TOTECS project can be a tricky affair. The reason is because Datapel's WMS system does not have any concept of what a category, or category tree is, or any specific place to store category data. So the question is how can you set up category data structures in the WMS system, and configure the Connector to make the impossible possible?
