My query is the current requirement of client is including B +TRA in a wage type for calculation of Absence deduction. Now their proposal is to have BS +TRA +SHIFT, But if the payroll goes retro it will change the deductions amounts which will take B+ Tr +shift up to now? So, from July 2013 we need the changed as absence deduction include B+TR+Shift but prior months of june 2013 it should be including the same as B+tR.
How to query the date control in schema to save retroactive run should calculate on previous calculation and new should be calculated from July 2013? What is the operation?
Please kindly help
