Please, can anyone help me first of all if there is possibility of searching in SAP customer account or an invoice/invoices by text (all sequence or part) from payment details. I noticed that on the customer accounts there are historic payment details and they match the new payments description. I would need to search by payment reference as the customers not providing their account with us or the invoice/s they paying for. Because this information are on the system it would be great if I could use it to search customers accounts or invoices.
Please, give me some advice on this. Can I use function which already exist or someone has to program it??
Regards,
MR
