Notification of Incoming Payments 
When a customer of yours pays an invoice, the customer’s bank sends you a Multiple Credit Advice (CREMUL) message with details of the payments that it has transferred to your bank account. When SAP ECC reads the message, it makes the appropriate accounting postings and clears the invoices that the customer has paid.
Note that here and in the following, the term “bank” includes the clearinghouse BBS (Bankenes BetalingsSentral).
...
1. You convert the CREMUL message into MultiCash format.
2. You process it using the Electronic Bank Statement program.
The program makes the accounting postings to reflect the payments that the bank has made for the customer and clears the open customer items against the payments.
