This document discusses configuring business transaction events (BTEs) in SAP to email electronic funds transfer (EFT) remittance advices to vendors. It describes finding relevant BTEs using transaction BERP, customizing an existing BTE function module to extract vendor email addresses from the SAP system and set the message type to internet, and configuring the BTE using transaction FIBF to activate it for a customer product. Testing is done by running a payment through transaction F110 to trigger the BTE, and viewing the email send requests in SOST.
