xTuple ERP has a number of privileges to control access to various parts of the application. Extension packages can define their own privileges or use those from the core. This article is currently a placeholder to allow documenting the privileges — what they are, what they mean, what package they belong to, and examples of how and where they are used. Since there are so many, each package, including the xTuple ERP core, has its own page of privileges. The Descriptions in the tables come directly from the priv table in an xTuple ERP database. They should be edited to make them more complete and meaningful. The Usage column is a placeholder for examples of where these privileges are used and what they control there.
