Open Amount Mismatch in Account Ledger and GRNI report(F43121)

Hello Team ,

I need to fix "Open Amt" discrepancy between Account ledger for GRNI report

Actually , I executed for GRNI report ( R43450) and i filter out the Open amount for specific RNV account . and then ,I check the Account details in Account Ledger P09200 ..

But after compare it , its shows A/C ledger Open Amt (Cumulation) is less than GRNI report Open Amt ..

So can someone help me to find out the cause and resolution to fix it .
