When I first was starting with MicroStrategy I worked with an Analyst who showed me the power of derived metrics by creating a dynamic copyright text. This method is not complex, but it was my first "ah ha" moment on the MicroStrategy platform.
Creating a dynamic copyright is easy. We will concatenate some text along with a dynamic year. The definition below contains the static information with the most recent year updating with the current year.
Concat("Omar's BI Blog Copyright 2019-", Year(CurrentDate()))
The Metric Output at the bottom of my document below
And that's it!
