How do I enable Position Incumbents validation?

The Position Incumbents validation prevents users from selecting a position in an assignment that doesn't have vacant Full Time Equivalents (FTEs) or headcount.

If overlap of headcount is allowed at the position, then a warning is displayed if the open FTE or headcount is exceeded. If overlap isn't allowed, users can't continue unless they select a different position that has vacant FTE or headcount. This validation is available out of the box if users have installed Oracle Fusion HCM for the first time. If users are already using Oracle Fusion HCM and upgrading it, then you must enable the validation to use it. To enable the validation:

1. Select the predefined Position Incumbent Validation (ORA_PER_EMP_POS_INCUMBENT_VALIDATION) context in the Organization Information extensible flexfield to view the Apply Incumbent Validation attribute in the Manage Enterprise page.

2. Select the Apply Incumbent Validation attribute in the Position Incumbent Validation section in the Edit Enterprise page.
