Removing overloaded function signatures for GetDefaultDrillthroughMDX and GetCustomDrillthroughMDX. Now if you want to force these functions to use the old algorithm for building the drillthrough statement where the code emits a member for every attribute even if it's just the default member then you have to specify the full parameter set .
GetDefaultDrillthroughMDX(Tuple tuple, int iMaxRows, bool skipDefaultMembers)
GetCustomDrillthroughMDX(string sReturnColumns, Tuple tuple, int iMaxRows, bool skipDefaultMembers)
