I'm interested finding out how to call or excecute a drillthrough action in SSAS 2005 from Excel 2003. I have a large rolap dimension and am unable to perform drillthrough using VB code. It works great if the dimension is MOLAP, but not ROLAP. When I use Excel 2007 I'm able to use the drillthrough action successfully with the dim as ROLAP or MOLAP. This problem is related to Excel 2003 and SSAS 2005. I hope someone can point me in the right direction. Thanks, -- Ron
