Summary

BizTalk maps are central to the process of converting documents between different internal formats and provide powerful capabilities to combine, calculate, and otherwise transform data items in addition to complex reordering and restructuring of data fields and records between the source and destination documents. The BizTalk Mapper allows you to interact with the source and destination specifications to create a complete and correct mapping between them. The Mapper includes comprehensive unit-testing features, including verification that the map will produce a valid destination document, and enabling you to test the mapping of generated or entered source values, or to test actual instances of the source document. Finally, the Mapper comes with a large set of built-in data transformation functoids with which you should become familiar to maximize your effectiveness in creating mappings between documents.
