It was a bit difficult to come up with a good title for this idea, but I think it could be a very valuable feature. Let me explain what I mean.
In many cases, you build dimension tables in the MDW/Prepare instance that are used in almost every SSL/Deliver instance. Examples include dimensions such as Date, Item, Customer, and so on.
When you add a column to one of these dimensions and want this column to be available in all SSL/Deliver instances, you currently have to add it manually to each one, which can be a lot of work.
It would be great if we could define a kind of Master Dimension and link the SSL/Deliver instances to it. Whenever something is added or changed in this Master Dimension, the update would automatically be applied to all linked SSL/Deliver instances.
