Very Computer

I am using Analysis Services and currently have a client
dimension. The table used to build this dimension has a
flag that identifies priority clients (prty_clnt_fg). I
have exposed this column by adding a member property and
would now like to build a virtual dimension that is based
on the value of this member property. i.e where
prty_clnt_fg = 1. Initially I merely created a view of the
base table and created a new dimension based on the view
which I thought would work. But when building the cube it
used this dimension in the join which resulted in
retrieving only the subset of clients (priority_clients).
Is there a best practise to follow for doing this as I
come across this problem often.

Hi ,

Based on my understanding, what you need is a virtual dimension with two
members: Is_Priority_client and Not_Priority_client. In the dimension
table, the prty_clnt_fg has two possible values: 1 and 0. Am I correct?

If it's true, you could:

1. Create a view on the dimension table, using "case when ... then...
else..." to convert the column prty_clnt_fg from 1/0 to a character column
with the values Is_Priority_client\Not_Priority_client.
2. Create the client dimension on the view, adding a member property based
on the new prty_clnt_fg column.
3. Create the virtual dimension based on the member property.

Thanks for your help. That worked fine.
