At least it would not be supported though the API can be somewhere in the code.

What is the execution plan? It was a feature of Analysis that resembles the actual execution plan from the Database Engine though it is not the same thing. What makes them similar (besides the name) is the final result, an XML that describes what happened. What makes them different? A lot of things such as no execution plan space for Analysis Services (the execution is done on the fly). Technically behind the execution plan feature was a tracing.


If the execution plan will make it in a future Service Pack or in the next version of SQL Server is not decided yet but what is sure is that SQL Server 2008 won't have it.

If you need this feature then please vote for it!
