Multiple users settle transaction for a single vendor for their respective branch. While doing settlement they are facing error 'Cannot edit a record in Open Vendor transactions (VendTransOpen). An update conflict occurred due to another user process deleting the record or changing one or more fields in the record'.

System must allow multiple users to settle transactions of the same vendor and same transaction till the available amount for settlement exhaust even the same is not posted. This is a business process where bulk transaction happens for a single vendor for apprx 50 branches and on account payment is made from HO and then all the invoices need to be settled with this payment.
