Automate lookup table maintenance when using multiple Excel sources in a PowerPivot model

When developing a PowerPivot model, one of the most important tasks is deciding which tables will serve as lookups. The urgency is due the fact that those tables define important elements as default granularity of aggregation as well as direction of filter context propagation(this last one explained here). Without valid lookups in your model, developing a PowerPivot report can be a bit frustrating as you constantly hit walls that arise when breaking fundamental rules of its calculation engine.
