0FC_OP_01 extractor issues- DFFKKOPBW data not matching with

Hi All

We have an issue with the extractor 0FC_OP_01. Our business is comparing the values in

R/3 report u2013 G/L Account Balance Display (t-code S_ALR_87012277) with the

Open Items by GL Account report in BW .(actually these values in the BW report are coming from DFKKOPBW table in R/3) .

But since august, the R/3 G/L account balance report is not matching with the DFKKOPBW table balances. So bottom line the extractor 0FC_OP_01 is doing something wrong when populating the DFKKOPBW table which is causing these two reports to be out of balance

Did anybody face this kind of issue before? Please Advise.

FYI : We are following the same procedure to populate the DFKKOPBW table as in the below article.
