When we built Tableau Prep, we put a premium on ensuring composability of operations: you can take the operations Prep supports and string them together in any combination you need. There are no restrictions based on where the data came from, or what operations came before.
This means that you never need to think about whether a particular operation is supported in your particular situation: if Prep supports it ever, Prep supports it always. Moreover, this gives you a lot of power to do what you need to with your data.
In the rest of this post, we’ll walk through a Superstore example that highlights this power.
