SoapFaultCode:4 Sender ( Unable to handle request without a valid action parameter. Please supply a valid soap action. )

Hi Experts,

Quick question, I had created a service consumer and logical port. Tried to test in SE80 (Test Service Consumer) but it return this error message.

I had tried this in SoapUI and it's work fine. Username and password are required to enter in SOAP Header but it's not appear in the Test Service Consumer.

<soap:Header>

      <ser:AuthenticationHeader>

         <!--Optional:-->

         <ser:Email>abc</ser:Email>

         <!--Optional:-->

         <ser:Password>123</ser:Password>

      </ser:AuthenticationHeader>

   </soap:Header>

Is it because of I have missed out this? If is how's the format should I enter in Test Service Consumer?

P.S. I knew there is a way to Concatenate the xml structure through ABAP but I just want to get a successful result in the Test service consumer.

Thanks a lot..

Regards,

Reid
