The following list contains some important things to consider when setting up your Microsoft Dynamics NAV security system.
The Microsoft Dynamics NAV security system is initiated when you create the first login. Until you create the first login, any user can have full access to carry out any transaction in a Microsoft Dynamics NAV database. Therefore, the first login that you create must be a superuser. The superuser must own and administer all access to the database from within Microsoft Dynamics NAV. We recommend that the user who administers security in Microsoft Dynamics NAV be a superuser.
One of the first things that the superuser should do is create logins for the other users that will have access to the database and grant them the appropriate permissions.
In Microsoft Dynamics NAV, a table can contain a FlowField, which generates sums based on values that are stored in another table. When using a FlowField, a user must have permission to read both tables or they will not be allowed to read the first table.
