With Microsoft Dynamics GP 2016 R2 now being available, there are some new security roles and tasks which need to be added.
As they have for the last few versions, Microsoft have made available some SQL Scripts to insert these roles and tasks.
The Dynamics GP 2016 R2 ones can be downloaded from directly from Microsoft or I have a post containing links to all of the versions I can find, which has been updated for Dynamics GP 2016, which is here.
The scripts tend to be cumulative, so if you upgrade from Microsoft Dynamics GP 2013 SP2 to 2016 R2, you only need to run the final script.
Not sure why I thought the scripts were cumulative, but they are not. All of the scripts need to be run in sequence for your upgrade path.
As always, when running scripts against Dynamics GP databases, ensure you have a good backup before starting.
