For permanent staff No need to DDO to release the employee. HOO Will release the employee from his/her login. After that DDO only have to do the LPC out from his/her login.

In that case if any HOO released any employee in wrong post to other HOO then at 1st new HOO have to joining in the employee then from DDO end have to rectify the post and approve it and then a forwarding letter should be sent to concerned Department to tag the employee the rectified post.
