calculated member on a dimension

In SSAS I have deployed a cube named HCSALES.This cube has 4 measures such as:
- UnitSold
- SalesValue
- UnitReturn
- ReturnValue

Now I want to add a calculated member bu using my DimProduct dimension. This dimension has an attribute named ITPP. And my desired calculated member formula is like this:

SalesValue - (ITPP x UnitSold)

How can do this? Any idea?

Please help

P.S
I have tried to do it several times. I have also attached a screenshot

Hi,

The value will only be calculable when there is a current value for the DimProductMAX dimension.

Try using [Measures].[SalesValue] - (DimProductMAX.ITPP.CurrentMember.MemberValue * [Measures].[UnitSold])

The suggest pratice from microsoft is to set the dimension also as Measure Group. Just click on the dimension table on cube design and set it as measre group. Then you can work with attribute ITPP as a measure!
 Try it!

Hello Pedro,
I have tried to apply the dimension attribute as a measure by using "new measure group" function. But I get an error such as:
"Object variable not set to an instance of an object". I have attached this screenshot as a png file.

And TimHumphries,
Thank you very much also to you. I have tried to apply your code snippet. But after cube processing all the calculated measure values are like these:
#VALUE

Is there anything wrong?

Hi,

As I stated, if you are using ITTP in the calculation, then it will only be valid of there is a currentmember value for the hierachy in the query. I can't see this dimension in your browser which is probably why the value is not being calculated.

Thank for your reply Tim,
The ITTP calculate member is always #VALUE. And tooltiptext is:

Parser: the syntax for "All" is incorrect

Go back... you made it wrong...
Follow the attached image to set a dimension as a dimension but also as a measure group.
Try it!
