When you deploy your BI project, it is very important for the users to take a look at the sets that they specified during analysis. This kind of action is called Drill through. It will retrieve first 1000 rows by default, yet you can change this property. For do that you must change the DefaultDrillthroughMaxRows property in the msmdsrv.ini file. This file is located, by default, in the :\Program Files\Microsoft SQL Server\\OLAP\Config folder.
