Wage type /564 (Advance payment) is a secondary payment created when
there are several payment runs.
Meaning of secondary wage type /564 for 'Advance payment'
Wage type /564 (Advance payment) is created when there are several
payment runs in a payroll period and the parameter 'Set flag for
transfers' on the initial screen of the data medium exchange program
RPCDTAx0 is flagged. This means that when payroll is repeated in the
same payroll period, the amount transferred until that time is stored in
wage type /564 (Advance payment) and subtracted from wage types /560
(Net pay) and /562 (Remaining net pay). Wage type /564 (Advance payment)
is created for purely technical reasons. The amount already transferred
is posted using the transfer wage types from the first payment run.
Wage type /564 (Advance payment) is not posted.
Saludos!
