No, the title is not a mistake. When you purchase Jet Enterprise, you also get a licence for Jet Professional. This ensures you get the full reporting capability available from Jet Reports. It also means that as well as following my series on Implementing Jet Enterprise, you should also follow the series on Implementing Jet Professional.
In the last post, on the Jet Enterprise sample reports, I said you could use the reports for both Jet Professional and Jet Enterprise, but forgot to say how. The how is because you have access to Jet Professional if you install it.
