Lakkaraju - it's a gross payroll mistake. Why were the employee's PF accumulations posted to his previous member ID?
It is a very common fact that a new/ separate member ID is created everytime a member starts tenure with an Organization.
Practical advice - please send a payroll correction form to your payroll department to correct the entries. As far as I know, the postings can be corrected in the next due month by passing corrected amounts. Please create a new member ID and link it to the UAN.
Otherwise, this will also cause an inconvenience to the employee also, as he/ she will not be able to claim any PF transfers in future. Please communicate to the employee about this error and assure him/ her of the corrections in a timely manner.
