Service Request Returns "Request is not allowed" Error Message

Problem

A client-side information system sends a service request and receives "Request is not allowed" error message as a response.

Request is not allowed
<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
  <SOAP-ENV:Body>
    <SOAP-ENV:Fault>
      <faultcode>Server.ServerProxy.AccessDenied</faultcode>
      <faultstring>Request is not allowed: SERVICE: instanceIdentifier/memberClass/memberCode/subsystemCode/serviceCode/serviceVersion</faultstring>
      <faultactor></faultactor>
      <detail>
        <faultDetail xmlns="">132ff5d7-a6c7-4807-968e-430c515bf32a</faultDetail>
      </detail>
    </SOAP-ENV:Fault>
  </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

Solution

The error message indicates that the client subsystem does not have sufficient permissions to invoke the service. Contact the service provider about the issue and request access permissions to the service. Don't forget to mention the subsystem that you want to use for accessing the service.
