I found Error while Execute Smart Object created by Service Object 

My Client Machine is working with the Service Binding setting as below 

<bindings>
<basicHttpBinding>
<binding name="BasicHttpBinding_GlobalDataService" closeTimeout="00:10:00" openTimeout="00:10:00"
receiveTimeout="00:10:00" sendTimeout="00:10:00" allowCookies="false"

textEncoding="utf-8" transferMode="Buffered" useDefaultWebProxy="true"
messageEncoding="Text">
<readerQuotas maxDepth="64" maxStringContentLength="2147483647"
maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
<security mode="Transport">
<transport clientCredentialType="Basic" proxyCredentialType="None" realm="" />
<message clientCredentialType="UserName" />
</security>
</binding>
</basicHttpBinding>
</bindings>
<client>

I want to know how & where to configure "Security Mode" in K2 for this specific Service Object .. 

 I changed in C:<InstallPath>WebServiceK2 Serviceweb.config , for the setting but the error is still the same
