Mass change of payment in customer line item for all open line item.

Hello,

We have updated the new payment as per the new agreement with customer in customer master. We want this new payment term should also be updated in all the open invoices which are not cleared. Is there are way we can do the mass change in Payment term as the open line item in the customer where line item are more than 50. Please let me know the transaction code for the mass change of payment term in Customer account balances.

Thanks and Regards,
