Making a Qualified Advance Payment 
Procedure

When an advance payment is created, a flag is set for transferred wage types. You cannot change the payee data and transfer amounts for these wage types, which are flagged as already transferred, during the correction phase. The employee would otherwise be rejected in the payroll run after the correction phase.
Result
You have effected a qualified advance payment and have transferred and run payroll separately for several of an employee's payments.
