I have a dataset which contains twocolumns, like this Year YearMDX 2010 [date].[year].&[2010] 2009 date.[year].&[2009] Within my parameter I use year as value and label. The value is used in SQL datasets. I want to use the YearMDX for MDX datasets, but how can I refer to this field YearMDX from my parametercollection while it only has properties like value and label? Thanks in advance Business Intelligence professional
