Community,
I save a sql server table once per month with a date at the end of the name. Same fields every month, it's a snapshot of our business. Something like 'Business_Data_08312016'
I'm trying to figure out a way to create a PowerBI report that looks at a rolling 13 months-worth of these tables. The only way I have figured out so far is kind of terrible, which is to make sproc that unions all of these together into one big table. It works but it's a major data duplication that doesn't seem necessary.
I am open to any ideas.
thanks.
