I would definitely ask this question as part of the interview process for Dynamics NAV developers (that is, if I had a chance to interview someone… ok, I should stop dreaming and come back to reality now). This question is quite good, because, you will know the answer only if you have encountered this question before.
So, how to display percentage sign (%) with MESSAGE function in Dynamics NAV? For example, if you would try
MESSAGE(STRSUBSTNO('You have %1%2 right now.',15,'%')); MESSAGE(STRSUBSTNO('You have %1%2 right now.',15));
you would get some interesting results (but not what you actually need):
After this, (the easiest way, of course, is to give up, right?) you might decide to use word “Percent” instead of sign “%” (which is a valid solution and I’ve seen this used many times). But, if you don’t like giving up, try something else! Well, to start with, you don’t really need STRSUBSTNO function in the message. Try calling MESSAGE function without STRSUBSTNO:
MESSAGE('You have %1%2 right now.',15,'%')
you will get:
