we are on oracle EBS -11i. we want to change the effective start date of an employee to a backdate in oracle HRMS (like in tables such as per_all_people_f, per_all_assignment_f etc.)
for example effective start date of any employee is 15 -jan-2012, we want to change it to 01-jan-2012 in oracle HRMS. Please suggest if there is any way to do so. Also, Please suggest the name of APi's which can be used.
