A requirement is to connect to external [webapi (SOAP)|http://demo.turtletech.com/latest/webAPI/CD_CB.asmx?op=InitiateConnectDisconnect] and get a result to SAP ECC. We are currently running on SAP ECC 6.0 without SAP XI or WEB AS.
The question is how to write abap program to call their webapi and get the result back to SAP?
I did some reseach and think that Enterprise service may be able to do this. Where should I get start on it?
