title: How to add new Dimension Attributes to the existing dimension through BIDS
body: <p>I have a customer dimension. While creating cube and defining dimensions the default attributes will come along with the cube creation. I want to add some more attributes after creating the dimensions. How to do this. I tried with "Add Business Intelligence" option, but I failed. Is there any way to do like that. If we remove the dimension and add the dimension again, we can have a interface as "Select dimension attributes". But with out deleting the existing dimension, how to add the attributes to that dimension. Following screen illustrates adding dimension attributes. How to see this interface for existing dimension.
