Use this code to pick the reconciliation that's bringing about the variance. Cancel that reconciliation and do it again. This code is for HANA;
SELECT "ExtrMatch", t1."DueDate", SUM("Debit") - SUM("Credit"), t1."DebAmount" - t1."CredAmnt" AS "Cleared Balance"
FROM "JDT1" t0 INNER JOIN "OBNK" t1 ON t0."Account" = t1."AcctCode" AND t0."ExtrMatch" = t1."BankMatch" WHERE t0."Account" = '1103' GROUP BY "ExtrMatch", t1."DueDate", t1."DebAmount",
t1."CredAmnt" HAVING abs(SUM("Debit") - SUM("Credit")) <> abs(t1."DebAmount" - t1."CredAmnt") ORDER BY "ExtrMatch";
