A Dimension Attribute with Double DataType converts a zero member to "(blank)"

In one of our SSAS 2005 sp2 cubes, we have a Dimension sourced from an Oracle table, with an Attribute that has a DataType of Double. When we process the Dimension and browse the Attribute, we see the following members:

All

-.01

-.002

.00000000001

.0000000001

Unknown

Notice how its blank where the '0' (zero) member should be. The underlying Oracle table does have '0' (zero) values for this column (you can see them when you explore the data in the DSV). To make things even more confusing,

the Unique_Name for this blank member is: [Dimension].[Attribute].&[0]

its Member_Value is: 0

its Member_Caption is: Null

its Member_Key is: 0

Has anyone seen this behaviour before? If so, how do we fix it?

Thank you.

Hi,

Have you set the NameColumn to look at the same field? And is it a datatype of WChar?

Hi Matt,

Thanks for the reply. Yes, setting the NameColumn to the field was one of the things i tried. The database field is NUMERIC(15,9), the KeyColumn is a datatype of Double and the NameColumn is a datatype of WChar. Even with the NameColumn set to the same field, I still get a blank where the 0 value should be.
