In previous articles, we discussed the importance of variables and how to optimize IF functions to reduce multiple evaluations of the same expression or measure. However, there are scenarios where the calculations executed in different branches of the same expression seem impossible to optimize. For example, consider the following pattern:
In cases like this involving measures A and B, there does not seem to be any possible optimizations. However, by considering the nature of the two measures A and B, they might be different evaluations of the same base measure in different filter contexts.
Read on for a couple of examples.
