Tag: data mapping

Referential what? it sounds weird, but it’s a rather basic thing: It’s like asking, do you have all the product IDs of the sales table in your product table? If you don’t, then is when that infamous «blank» appears in slicers and all kind of bad things start to happen. Unless you load everything from a pristine data warehouse, you should actively check these things, like after each refresh. It’s one of these things that you should do, but normally does not make it anywhere close to the top unless results look way off. If there was an easy way to check that…

They will tell you that they update it whenever a new value appears in the datasource, but if you double check this statement you might get let’s say «mixed results» at best.

Nothing says «there is a problem» as a red button appearing in your report. And if it offers «actionable insight» on how to solve the problem, so much better. So this is what we’re going to do: A data problem button.
