Codeunit interfaces in AL
Nearly two and a half years ago I had a dream. It was about codeunit references and codeunit interfaces. And today, nearly two and a half years later I am still here, still having the same dream. We still cannot do codeunit interfaces in AL. But it doesn’t mean we don’t need them. We do. We badly do.
Two things triggered me to write this post about how badly we need codeunit interfaces, or any kind of polymorphism: a NAV TechDays talk, and a github project I saw.
