such forms like 5/10 are not needed at present as online submission and approval or entry and exit details facility is available at employer portal.
Nomination facility is transferred to employees itself and they can do it by self by using member portal
in case of any mistake made by employer side towards joining date and exit date, physical forms may be asked by department , but it would cause a jeopardy to employer as it will establish willful intention of wrong data entry
so one has to be careful while making data entry online, always, as any further change or correction would not be easy for the employer / employee or HR person
