Error SOAP:1.001 CX_ST_GROUP_MISSING_CASE while calling a method

Former Member — Tue, 21 Apr 2015 13:02:08 GMT

Hello,

After having generated an ABAP proxy consuming class for a SOAP Web Service, I'm calling one of the methods in a program but the resulting return is empty. So I've tested the same method in SE80 to find out what's going wrong and I'm getting the following error:

SOAP:1.001 CX_ST_GROUP_MISSING_CASE:.Element {http://www.indexeducation.com/frahtm/HpSvcW.html}return missing.

Here is the complete answer from the call:

<n0:NombreCoursResponse xmlns:n0="http://www.indexeducation.com/frahtm/HpSvcW.html" xmlns:NS1="http://www.indexeducation.com/frahtm/HpSvcW.html" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"><return xsi:type="xsd:unsignedInt">15545</return></n0:NombreCoursResponse>

the message seems correct, I think I've missed something during the class generation but can't find what.

Thanks

Hi Jerome,

Your webservice looks like RPC-encoded. Correct me if I am wrong, but I think

consumer proxies are document-literal. When you load a wsdl in PI 7.1 and above

you have the option to use rpc, not sure if you have that option when you load

the wsdl directly in se80.

Regards,

Mark

Hi Mark,

yes the service is RPC encoded, and I didn't saw an option for this when I created the proxy. I used the RPC encoded because I'm facing another error when I'm trying to generate the consumer proxy with the document/ literal version of the wsdl.

The generation stops and I get an information message "message part refers a type not an element"

The problem is in the response message:

<wsdl:message name="ReponseNombreCours">

<wsdl:part name="return"

type="xsd:unsignedInt" />

</wsdl:message>

Regards

Hi Jerome,

Can you paste the wsdl here? You can leave out the endpoints.

Regards,

Mark

Hi Mark

Hi Mark,

the original WSDL is huge, I've made one with one method and the problem I mentionned:

Hi Jerome,


 The problem is in the response message:
  <wsdl:message name="ReponseNombreCours">
    <wsdl:part name="return"
               type="xsd:unsignedInt" />
  </wsdl:message>

Yes, that is indeed the problem. Here's what I did

1. Added a new complex type in the wsdl:types section


<xsd:element name="ReponseNombreCours">
        <xsd:complexType>
          <xsd:sequence>
            <xsd:element minOccurs="0" maxOccurs="1" name="return" type="xsd:unsignedInt" />
          </xsd:sequence>
        </xsd:complexType>
 </xsd:element>

2. Refer this on the wsdl:message


  <wsdl:message name="ReponseNombreCours">
    <wsdl:part name="ReponseNombreCoursType" element="hp:ReponseNombreCours" />
  </wsdl:message>

You should be able to regenerate it (document-literal) in sproxy now.

Mark

Hi,

Yes, in the messages section choose RPC Style.

Hi Mark,

I tried what you suggested, but I still have a message during proxy generation:

"Proxy generation terminated: Message must have exactly one part"

You were able to generate the proxy after modifying just this?

Jérôme

Hi Jerome,

Yes, I was able to regenerate it on my PI system. I guess you have no choice but to attach your wsdl here (you can still remove the endpoints or replace important namespaces, structure names etc).

Mark

Hi Mark,

I had this message using the proxy generation assistant from SE80.

I joined the WSDL I used to this reply.

markangelo_dihiansan — Wed, 06 May 2015 05:15:55 GMT

Hi Jerome,

There is an import statement in your WSDL


     <xsd:import namespace="http://schemas.xmlsoap.org/soap/encoding/"      schemaLocation="http://schemas.xmlsoap.org/soap/encoding/" />

I'm not sure how to do this via se80 though. In PI, you can easily see the two definitions. The xsd can be downloaded from http://schemas.xmlsoap.org/soap/encoding/, but you need to link it to your wsdl for the proxy generation to work.

Regards,

Mark
