API User Hooks and PERWSHRG (Combined Person and Assignment Form)

 I have ran the $PER_TOP/admin/sql/hrahkpar.sql script.  The output contains both the Before Process and  After Process hooks for the CREATE_EMPLOYEE  Business Process API I have created a PL/SQL package that updates a custom table and have tested this package and it works as designed.  I then created the user hook and ran the pre-processor (hrahkall.sql).  If I call the hr_employee_api.create_employee directly the user hook fires and updates the custom table.  If I use the combined person and assignment form (PERWSHRG V11.5.108) the user hook does not update the custom table.
