Up-to-date list of VBA Functions in MDX

Reposted from Chris Webb's blog with the author's permission.

Some of you may be aware that a few VBA functions have been implemented as native MDX functions to improve performance. I blogged about this a few years ago, but I've now received an up-to-date list of all the VBA functions that that this has happened for as of SSAS 2012 SP1 from those nice people on the SSAS dev team:

CDate
CDbl
CInt
CLng
CStr
Int
Month
Now
IsArray
IsError
Abs
Round
InStr
LCase
Left
Len
Mid
Right

As far as I can see, it's Month() and LCase() that are the new ones on this list, and which were added in 2012 SP1. Still no Log10() function though, alas.

Thanks to Akshai and Marius for their help with this.
