Hello Sikindar
No, there is no DOJ concept here here
When we enter the wage type for the employee in IT0014, start date could be anything but we want to define the End date (Automatically) 13.5 Months from the start date
So key aspects are
EE number, IT0014, WT and start date of that entry
(if End date entered as 31.12.9999 or anything entered then while saving it should change to 13.5 month of Start date)
