Changing PAYE Details for a Leaver 
When an employee leaves your company, you should record that a P45 has been issued to this employee and the date on which this occurred.
Procedure
The Maintain HR Master Data screen appears.
Use the matchcode function to find a number you do not know.
The Copy Tax Data GB screen appears.
A message appears informing you that the end date of the previous record will be delimited.
Result
The employee’s PAYE details are changed. If the employee was on strike at the time of leaving, any tax refund withheld is paid with the final pay.

You can also use the Sample P45 Slip (RPCP45G0) report to record an employee's leaving details and to update the Tax Data (infotype 0065) records. For more information, see
