Error - The type NavOption is unknown.

Hi guys,

I would like to share the solution to the error which came up with me while developing a report. It is quite a silly mistake which beginners like us make often.



Solution : Go back to the C/AL code and look up that you must have typed a wrong GET statement there.

In my situation, I was doing

SalesHeader.GET("Sales Line"."Document No.");  //Wrong GET

which resulted in 'The type NavOption is unknown.' error.

I corrected my code and wrote,

SalesHeader.GET("Sales Line"."Document Type","Sales Line"."Document No.");  //Correct GET

And this issue was resolved. Hope you will find this useful.

Cheers!
