Two PERNR for an Employee Possible?

Hi Friends,

I have two categories of Employees.

a. Satff - Pernr in series 3

b. Workers - Pernr in series 2

<b>When one worker is promoted to Staff, his PERNR changes.</b>

<b>But will this bring all his old Payroll data ? Is it Legal to have 2 F16?</b>

OR <b>we'll have to keep one PERNR throughout</b> ?

Would really apreciate your Reply.

Regds,

Sri
