Error while terminating employee

Hello

We are facing one issue in HRMS employee termination. When we terminate any employee,its assignment details updated wrongly.

For example: -  I have created one employee eith effective date as 29 Mar 2012. I want to terminate it on 29 Mar 2012 itself. After termination, its per_all_people_f gets updated with inactive record w.e.f 30 Mar 2012 (2 ROWS). But in per_all_assignments_f it just end date the effective start date to 29-mar 2012 But doesn't have record w.e.f 30 Mar 2012 (1 ROW only). It should contain 2 rows in assignment table. It is happening for some employees.

We are on 11.5.10.2
