At c: you find an xml file – SoapTraceConfig.xml – where you can enable the soap logs.
<?xml version=’1.0′?>
<SoapTrace>
<!–Possible Flag values: AllRequests, FailedRequests, SuccessfulRequests, NoRequests–>
<Flag>NoRequests</Flag>
<!–Absolute path to store Soap Request/Response Xmls. –>
<FilePath>C:\SoapLogs\</FilePath>
</SoapTrace>
You just have to replace the Flag value by AllRequests to get detailed log files
