Jet Express is a Microsoft Excel add-in included with Microsoft Dynamics NAV and Dynamics GP, which gives users a simple way to create basic reports and business queries inside Excel.
In Jet Express, you can use the GL or NL(Table) functions to your reports.
If you attempt to run a report that has any other type of Jet function [such as NL("Rows"), NL("First"), etc.] an error will be displayed to let you know that the particular function being used is not available in Jet Express.
Reports created with Jet Professional may required that they be run using Jet Professional.
Any report that is to be run using Jet Express for Excel must only contain those functions available within Jet Express for Excel.
