Retro Set through PCR for IT0008 (Round-off) PCR XVAL into ZVAL

Dear Experts,

I wrote the PCR for IT0008  for round-off. This is working fine, but when i will apply to production, that time already having the Jan Salary retro.

But here I want to stop the retro from Feb'2014 month and apply the revised PCR for round-off.

For Reference : IT0008 Round off  -  I have copied from PCR XVAL into ZVAL

Thanks in advance.

Regards,
