MDX Calculate minimum price at a higher level of granularity

Question

Hi all!
I can't find my way to calculate the following scenario in SSRS mdx statement: I need to know the "category best price" of a product category at a lower level of granularity. See example below:
Category:         Subcategory:        Price:        
Category Best Price?
Adventure         Bikes                   110            105
Adventure         Kayak                  120            105
Adventure         Running Coat        105            105
Fitness             Training Shoes       80              75
Fitness             T-Shirt                  75              75
I need to undestand how can I build the Calculated Measure to get the "category best price" column! Note that in the real scenario, there are much more values in the rows, so the granularity is much higher. Additionally, the attributes doesn't
belong to the same dimension.
Thanks a ton for your help!

Hi mts_aa,
According to your description, you want to show lowest price of each Category group in each row. Right?
In this scenario, we can generate this column in MDX query level. Please refer the query below:
with member [Measures].[MinChildren]
as
min([Product].[Product Categories].currentmember.parent.children,[Measures].[Price])
select {[Measures].[Price],[Measures].[MinChildren]} on 0,
[Product].[Category].[Category].members*[Product].[Subcategory].[Subcategory].members on 1
from
[MDX]
Also you can do this on report level. You just need to have the records group on Category. Then use the expression below in detail row:
=Min(Fields!Price.Value,"Category")

If you have any question, please feel free to ask.
