API Provider Setup
To authenticate an SAP R/3 BAPI element instance you must use your SAP R/3 user and password. You also must include the URL or IP address of your SAP R/3 account, for example
https://myserver.s4hana.ondemand.com, as the Host Name. Lastly, use the Instance Number and System ID from the System Entry Properties (see below). Contact your system administrator to get the information.
