When implementing an existing payroll mid tax year the 'Previous Payroll Code' must currently be uploaded twice, as after the parallel parun the value disappears and would not be reported on the first live FPS file.
To ensure employee YTD figures are not duplicated by the HMRC, we currently have to re-uploaded the CSV file with the employees 'Previous Payroll Code' once we open the live payrun.
Idea is for the 'Previous Payroll Code' to be held until the first live payrun so we dont have to rememeber to re-upload the CSV file once the live payrun is open.
