I have a cube(multidimensional) in SSAS which contains a dimension with a period hierarchy(year, month, periodcategory, periodcode) and a measure "Amount"
Now i try to make a calculated measure which returns the value Amount for the previous month - value Amount for the current month (this will then only be different from the current amount when drilled down to month in the period hierarchy). I read a lot of posts already about ParallelPeriod function or lag(1) but i don't see how this could help me in this case.
Any advice would be really helpful.
