Don’t post payroll results to FI for several months.

Hello, Experts.

An employee has his payroll results, but his payroll results haven’t been posted to FI during 20 months.
Now my customer decided to post his payroll result to FI from Jul-2012 but remain the past payroll results without FI posting.

[Case]
(1) ~ Oct-2010: posting to FI
(2) Nov-2010 ~ Jun-2012: don’t post payroll results to FI for this period.
(3) Jul-2012 ~: posting to FI

When I executed RPCIPE00 for Jul-2012, the posting result was generated from Nov-2010 to Jul-2012.

Can you tell me some advices to solve this case?
