Last week while reading Bill Anton’s blog (which is, by the way, highly recommended) I came across a link to a page in Books Online that I hadn’t seen before: a list of deprecated and discontinued functionality in SSAS 2014. Here it is:
The most interesting point is that the Non_Empty_Behavior property on calculations will not be supported in SSAS v.next. I still see this property being used a lot, and as I show here if you use it incorrectly it can give you bad results. Although I have seen a few cases where it has been necessary to set Non_Empty_Behavior (for example here) they have been very, very rare and I think deprecating it is the right decision. Other than that, remote partitions, linked dimensions and dimension writeback will also be no longer supported in a ‘future’ version, but I don’t think anyone will be too worried about those features.
