Tip #69 | Default Implementation for AL Interfaces

I just love it when I get an error and nothing I search for answers what to do next.

Value ‘ ‘ does not implement interface ‘ForNAV Layout’ and there is no default implentation for the mentioned interface.AL(AL0596)

There is no mentioning of default implementations in the Microsoft documentation.

During NAV TechDays 2019 there were a lot of sessions that I would describe as “develop Business Central doing minimum development using AL“. Sounds weird? For me yes… at least at the beginning.

Speakers, such as Arend-Jan Kauffmann (https://www.youtube.com/watch?v=cp848e9WBFs), showed how to connect Business Central with Power Apps or use Power Automate (previously named Flow) and our BC. And my first impression was – noooo way it can be so easy.
