Ya Praneeth,
Users have changed IT 8 w.e.f 01.04.2014 bcoz of some change in pay structure of some of employees. how ever they have uploaded the values through bdc variant. i came to know that. after that they are reporting previous records are showing 0 values all the wage types are IndValuation. they are worrying about when they go for retrocalculation, it could be a big problem. but it is running payroll with the current changed values for further payroll periods. Thats the problem Praneeth. Actually i am busy with another issues which should be done before this pay period, thats why i was too late to respond to you.
Thanks,
Aruna.
