I have a dimension which has the following data
Duration refers to the dfference between start date and end date .
PreSalesStart date is nothing but subtracting 31 days ( the duration ) from the start date and PostSalesEndDate refers to the addition of duration period to the End Date .
I have a cube which returns me the sales which happened between the start date and the end date . ( I have a separate time dimension which is related to the fact table )
Now when i try to find the sales which happened between the presalesstartdate and startdate . i am not getting null in the display .
I have tried using the mdx as follows
Please let me know what i am missing, i am sure it should be something with the logic that i am applying and not on the syntax because i am not getting any #value error while displaying the data
