Understanding the Document Classes
A PeopleSoft document is a managed object that has two representations. The logical document depicts the document’s structure. The physical document is the rendering of the document in a specific format—either in XML or as a relational record (or records).
PeopleCode provides document classes that contain built-in functions and methods that enable you to populate data into and retrieve data from logical documents. However, you should already have knowledge of the logical document structure in order to effectively write PeopleCode to work with a specific document.
