Column calculation applied to all rows with 1 exception

[Aspire]

Hi guys,

I'm using dimensional database and have troubles defining my column expression in order to apply a calculation to all my rows except one which should have another expression formula.
The formula I tried where CASE and IF Statement:

if ([great_outdoors_company].[Products].[Products] = 'Iphone') then formula1 (which is using tuple expression)
else formula2 (tuple expression)

I also tried the caption function: if (caption([great_outdoors_company].[Products].[Products]) = Iphone) then ...

but without any results.

I would like to hear your suggestions!

Thanks

Hi again,

Can anyone tell me at least how can I make a reference to a specific line in my rows (using dimensional db)?

thanks

database = dimensionally modeled relational (DMR)?
It might be illuminating to post the expression you are trying to use, rather than the abstract expression you show.
Without any results - Do you get an error message, or just no value displayed? Have you tried just showing the predicates in your expressions as data items, to simplify what is not working.

Row number - if you could calculate it - would almost always be a poor choice. Is there something special about the data on that row? If so, your expression should reference that.

Thanks for the suggestions bdbids  ;)

It's DMR.

Actually, I succeeded to apply the formula thanks to the caption function with if statement. And then basically I can make a reference to a specific row element via its description through caption.

cheers
