The Windchill Business Reporting (WBR) solution uses Data Source objects to retrieve data from Windchill. One type of Data Source is an Info*Engine task. An Info*Engine task is a text-based document that uses programmatic constructs to retrieve and manipulate Windchill data. The task must return its data in a tabular format (i.e. each element must have the same number of attributes) and task must be commented with special tags and syntax to define it as a WBR Data Source.
