Clarifications in External Reconciliations

Hi experts,

Need your valuable suggestions for the below raised situation in Banking reconciliations.

One of our client is doing bank external reconciliation through Manual Reconciliation.

Last time when he is doing the reconciliation, he selected the bank code and entered the Ending Balance as INR 95,27,966.20.

And he reconciled with some open items and updated.

Again when he is doing the Manual reconciliation for the same bank account, system is showing last balance as INR 7,833,660.04.

Also some previously reconciled transactions are also enlisting as open items.

Client functioning in SAP 8.8 PL 21.

Kindly provide some valuable suggestions.

Regards

Ravindran Srinivasan
