Incorrect line item reflected in FAGLB03 report

Hello Experts,

We have an FI document posted via tcode VF02 in FY 2017. This FI doc is a reversal document of FI doc generated via billing doc (VF01) in FY2016. The FI doc posted in FY2017 is reflected in FAGLB03 report in FY 2016 period 01. We are using calendar year as fiscal year.

Any idea why the doc posted in FY17 is reflected in FY16 of FAGBL03 report? I've looked thru the forums and sap notes but haven't found anything related.

Any inputs would be greatly appreciated.

Thanks!

Morris
