Excel template file

This file must contains one and only one sheet per Opinum Data Hub entity: site, source and user. Two additional sheets define the configuration and mappings/transformations: mappings an config.

All entity template sheets share the same entity sheet structure, while the mappings an config sheets have their own structure.

Event if the Master Data Upload file is intended to manage a single entity (e.g. Users), the template must contain the configuration of all entities (site, source and user) because the MDE must know how to fetch an entity based on it's business key.
