Integration Services Drill-through is a server-based form of relational drill-through. Like conventional relational drill-through, you can construct liaisons between OLAP and relational data sources. Unlike conventional relational drill-through, you can drill to the relational document from intersection in the Web Analysis document.
Your Essbase Administrator must establish Integration Services drill-through documents. The relational query is stored as Intersection metadata, and flagged with an LRO indicator. When you double-click flagged cells, the OLAP document navigates to the specified relational document.
