The tables below give an overview of how to activate user exits. A comprehensive description of all user exits including detailed information on how to activate them is contained in the section User Exits of this documentation.

Note
The user exits U-MODEL and U-XREF are activated in the Metadata Administration. U-PGMLA, used to define new programming languages to Predict, is always active.
