Record-level security allows you to limit the access that a user has to the data in a table. You do this by specifying that the user only has permission to access certain records in the table. Record level security is only available in Microsoft Dynamics NAV with Microsoft SQL Server.
Record-level security is implemented by applying security filters to the tables and the table data that a user has access to. You can specify, for example, that a user can only read the records that contain information about a particular customer. This means that the user cannot access the records that contain information about other customers.
