Which three data sources can you synchronize in a Web Intelligence 4.0 document (WID)?

Personal data files such as CSV or Excel imports can be included in a multi-source document and synchronized with other queries using merged dimensions.

Stored procedure data sources are not supported for data synchronization via merged dimensions in Web Intelligence 4.0 documents.

Multiple queries built on the same universe can be synchronized by merging dimensions that share the same object definition, a common use case for combining related data sets.

Queries from different universes can also be synchronized through merged dimensions as long as compatible dimension objects are mapped together, enabling cross-universe reporting in a single document.
