Vendor Invoice Mapping Concepts

Key requirements for setting up an XML mapping are as follows:

1. A single root element must be present, with all other lines indented accordingly.
2. Element names must comply with XML element naming rules, which are case-sensitive and must start with a letter or underscore. Names cannot start with "xml" or contain spaces.
3. Attributes with an element must have unique names and cannot have child elements.
4. Each XML field can only map to one draft field unless it is a search field.
5. Employee and vendor numbers are search fields and should be marked as such.
