Security configuration for external tables

A PI AF table can be linked to data from external data sources such as Excel, Access, SQL Server, or other OLEDB/ODBC data sources. A PI AF table linked to an external data source is called a linked table or an external table. There are potential security risks for external tables in general. Risks vary depending on how an external table connects to the foreign data source.

You can restrict the use of certain connection types. You can also disable external tables altogether. The following sections explain how external tables get their data and what the security options for external tables on a PI AF server (machine hosting PI AF application service).
