Web service for CREATE_TRIP_DATA

[Former Member]

Hello,

I am very new to SAP and webservices and have an issue with getting a response from a web service I created for a simple function module BAPI_CREATE_TRIP_FROM_DATA. I am getting the following response for the SOAP request from soapUI:

<soap-env:Envelope xmlns:soap-env="http://schemas.xmlsoap.org/soap/envelope/">
   <soap-env:Header/>
   <soap-env:Body>
      <soap-env:Fault>
         <faultcode>soap-env:Client</faultcode>
         <faultstring xml:lang="en">Dynamic function call failed</faultstring>
         <detail>
            <n0:DynamicFunctionCallFault xmlns:n0="http://www.sap.com/dynamic-call">
               <FunctionName>BAPI_TRIP_CREATE_FROM_DATA</FunctionName>
               <ParameterMissingFault>
                  <DescriptionText>Function call of BAPI_TRIP_CREATE_FROM_DATA failed; the obligatory parameter EMPLOYEENUMBER</DescriptionText>
               </ParameterMissingFault>
               <Caller>
                  <Class>CL_SRG_RFC_PROXY_CONTEXT</Class>
                  <Method>EXECUTE</Method>
                  <Positions>1</Positions>
               </Caller>
            </n0:DynamicFunctionCallFault>
         </detail>
      </soap-env:Fault>
   </soap-env:Body>
</soap-env:Envelope>

I am using ECC 6.0 with GUI 7.10. soapUI is v3.5.1.

What is hard to find also is the purpose of the class / method mentioned ... nothing on googling either. All the errors seem to be on the DECODE method of the same class which is to do with serialization error, my issue is with the EXECUTE method.

Hi everybody,

I don't know whether you have solved this issue or not. I've found out the cause and a workaround to avoid the error.

As the error description says, the problem is in the Employeenumber field. The BAPI_CREATE_TRIP_FROM_DATA FM has the same name both for an input and an output parameter. Once you create the WS, only one descriptor remains in de WSDL and the FM is called wrongly.

To avoid this problem I have encapsulated the standard FM BAPI_CREATE_TRIP_FROM_DATA into a ZBAPI_CREATE_TRIP_FROM_DATA that hasn't got the output parameters employeenumber and tripnumber. Once you create the WS out of this FM you won't get the error.

This is the code for the FM:

FUNCTION zbapi_trip_create_from_data.

Hi guys,

Could you sort this issue out ?

I'm having the same issue, employeenumber is valid in SAP HCM filled in the soap xml request and yet I'm getting this error message (missing mandatory field employeenumber)...

Thanks.

Complete SOAP Request:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
   <soapenv:Body>
<urn:ZbapiTripCreateFromData xmlns:urn="urn:sap-com:document:sap:soap:functions:mc-style">
<Employeenumber>00001000</Employeenumber>

<Ort01>2035 Lincoln Hwy</Ort01>
</Framedata>
</urn:ZbapiTripCreateFromData></soapenv:Body>
</soapenv:Envelope>

I looked at one option: putting a wrapper around the BAPI itself and changing the type of 'Employeenumber' in the importing to a more common data type such as Char8 to see if it was a serialization error. That still gives me this response:

<soap-env:Envelope xmlns:soap-env="http://schemas.xmlsoap.org/soap/envelope/">

I am providing Employee Number in the right format in the Soap request as:

<Employeenumber>00002000</Employeenumber>

Inspite of this I get the same error in the response. It works perfectly when I test the FM in the SE37 transaction. Any suggestions?

[Former Member]

Can you post your request xml here?

[Former Member]

Hi,

You are right, I also created same service and even though supplying correct data service is throwing exception:

I found that datatype of Employeenumber is correct:

- <xsd:simpleType name="numeric8">
- <xsd:restriction base="xsd:string">
  <xsd:maxLength value="8" /> 
  <xsd:pattern value="\d*" /> 
  </xsd:restriction>
  </xsd:simpleType>

Need to investigate further.

Hi guys,

I'm facing the similar issue. Just wante to add up some more points.

Upon analysis, I could find that this is because of the same name given to the 'Import' and 'Export' variables in the BAPI/Function Modules. These values are somehow not being interpreted by the Webservies because of the similar name.

Still investigating on how to resolve this.

Naresh

Error message says, you didn't provide 'Employee Number' for a necessary parameter.

Check your FM source code for any missing parameter.
