how to post to accounting in current period for previous payroll result unposted

dear Gurus,

i have a reference that SAP can do posting to accounting in current period for previous payroll period (unposted) automatically. is it right??

it happenned that one admin payroll forgot to do posting to accounting of previous payroll for one payroll area.

for other payroll area, all posting to accounting for previous payroll has been done..

and period FICO for previous period has been closed. It can not be re-open - it is the management decision.

I have done the testing, now in the current posting to accounting, the previous period payroll unposted not included in current posting

Is it related with customizing to do posting of previous payroll result unposted?

We also want to avoid manual journal for the previous payroll result unposted. Is it possible for SAP - for certain payroll area - to to posting to accounting for current period payroll and previous period payroll in the same time?

Need your guidance..

thanks and best regards, pei pei
