A user exit is a spot in programming logic where a customer can insert their own logic.  This can take several different forms, within the application.

A) [User Calcs|USERCALC] - This is a end-user oriented mechanism of inserting specific logic at various points in Benefits or Attendance processing, in the Payroll Cycle

B) Reactive [Workflow|WORKFLOW] - This is logic that is called just before the record being inserted / updated / deleted is committed to the database.

C) Specific Logic points that are configurable, but require a PL/SQL function to be defined
* This is generally controlled with a function level preference so that different screens may have different logic.
**[FTE_CHECKING_ROUTINE|FTE_CHECKING_ROUTINE (System Preference)] - for posting based screens like IRPO to validate/set FTE values
**[DPS_AVAIL_EXIT|DPS_AVAIL_EXIT (System Preference)] - for posting based screens like IRPO to control if a position is valid for selection
