DTD Files for Loading and Importing Supplier Data
There are two methods to load data in Windchill Supplier Management.
Use csvmapfile.dtd – This DTD allows you to load all types of objects related to Windchill Supplier Management supplier organizations, suppliers, supplier contacts, supplier documents, sourcing contexts, manufacturer parts, vendor parts, AML/AVL entries, and sourcing status values. This method is typically used for the initial loading of supplier data as it allows you to load multiple objects in the same XML file.
Use suma_ixb.dtd – This DTD allows you to load manufacturer and vendor parts, sourcing contexts, and AML/AVL entries. This file format is also used when exporting from and importing data into Windchill Supplier Management.
