Hi Ajay,
Thanks.
Yes indeed we referred the User Exit option as described in SAP Note 494777, however it's getting complex as the combination & cryptic manner of billing document received in Notes to Payee is always different.
Assume if customer makes payment for 10 Open Billing Document, it would give only last 3 digits of all billing document together & if the same customer pays for 5 Open Billing Documents than it gives last 4 digit of Billing document.
I tried understanding a statement in help.sap (String Search for Document Numbers - SAP Cash and Liquidity Management - SAP Library)
"First character omitted
The customer regularly receives invoices with the following type of document number: 18000XXXXX . These numbers always start with 18000, so the customer omits these digits given that they contain no important information."
Achieving this with Search String is what I am struggling, I tried with all possible match characteristic but never achieved the above statement.
Thanks.
