Here is a small trick that I have used a couple of times to turn the report selections into a selection dialog in Microsoft Dynamics NAV.
The report selection table in Dynamics NAV is used to specify what report(s) to run when a user prints a document such as an order confirmation. Part of the report selection functionality is the ability to define more than one report to print at the same time; you can for example have Dynamics NAV print three different documents when the user prints an order confirmation. This is done by listing the reports in the reports selection table in a defined sequence.
