REG : Validation for the temporary employees in ESS

Hi Gurus,

I have a doubt here and need your help.

I have developed a leave application, wherein I need the following validation.

• contract employee throw and error :

---> Achieved by checking persg = 'C'.

• If the employee is a temporary employee throw and error

---> Achieved by checking persg = 'B'

• if the temporary employee has less then 12 months of continuous service.

---> Achieved by checking getting the hired date and getting the difference between dates in months and comparing the months with 12 months.

• If the employee is a temporary employee who got hired less then 12 months  from the current date.

-----> Looking a resolution for this....

• IF the temporary employee who got hired more then 12 months from the current date but not continuous in service, i.e has a leaving action in between , then throw an error message.

-----> Looking a resolution for this....

Please suggest resolution for the last two issues.

Thanks,
