On Jan 27, 2022, I presented to the Baku Meetup group organized by Ilgar Zarbaliyev. I looked at scenarios where we need to use parameters and custom functions in Power Query. They allow you to make your solution dynamic, easier to maintain while generating the results with less effort.
Comments about this presentation:
“I really enjoyed you Baku meetup presentation. Your explanation and examples of the Custom Functions with Parameters was probably the clearest I have seen. It really helped me get a few things straight in my own mind.”
