Microsoft Dynamics NAV Classic client has some features which are simply unbeatable when it comes to productivity and speed, one of them being primary-key filtering. When you set a single-value filter on primary key fields in a table, and then insert a new record in the same table, primary key fields are automatically populated with values from the filter.
Well, there are so many ways to (ab)use this feature, that sometimes it has a potential to save ridiculous amounts of time. As it just did for me, so I felt an irresistible urge to share it with you. Even though it is so ridiculously simple.
