RABAX - ManageCuatomerIn - While creating a new account

Hi Experts,

I am trying to create a new Ship-To Account using ManageCustomerIn SOAP service.

This Ship-To Account has to be related/ linked to another Sold-To Account using Is-Ship-To-Party-Of relationship.

I am able to do so with the below request XML. But the the same XML with same data fails intermittently giving an RABAX exception.

Request:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:glob="http://sap.com/xi/SAPGlobal20/Global" xmlns:a01="http://sap.com/xi/AP/CustomerExtension/BYD/A01Q1" xmlns:ymn="http://0000159922-one-off.sap.com/YMN5Q7R8Y_" xmlns:yng="http://0000159922-one-off.sap.com/YNGLNLRVY_" xmlns:yod="http://0000159922-one-off.sap.com/YODNFKN0Y_" xmlns:glob1="http://sap.com/xi/AP/Globalization">

   <soapenv:Header/>

   <soapenv:Body>

      <glob:CustomerBundleMaintainRequest_sync_V1>

         <Customer actionCode="01">

            <CategoryCode>2</CategoryCode>

            <CustomerIndicator>true</CustomerIndicator>

            <Organisation>

               <FirstLineName>Account Name</FirstLineName>

               <SecondLineName>Second Name</SecondLineName>

            </Organisation>

            <yod:AccountGroup>02</yod:AccountGroup>

            <IndustrialSectorCode>Z11000</IndustrialSectorCode>

            <LifeCycleStatusCode>2</LifeCycleStatusCode>

            <AddressInformation actionCode="01">

               <Address actionCode="01">

                  <CorrespondenceLanguageCode>RO</CorrespondenceLanguageCode>

                  <PostalAddress>

                     <RegionCode>01</RegionCode>

                     <CountryCode>RO</CountryCode>

                     <CountyName>Romania</CountyName>

                     <StreetPrefixName>Street Prefix</StreetPrefixName>

                     <StreetName>Street Name</StreetName>

                     <CityName>City Name</CityName>

                     <StreetPostalCode>100212</StreetPostalCode>

                  </PostalAddress>

               </Address>

            </AddressInformation>

            <Relationship actionCode="01">

               <RelationshipBusinessPartnerInternalID>10035072</RelationshipBusinessPartnerInternalID>

               <RoleCode>CRMH02-2</RoleCode>

            </Relationship>

         </Customer>

      </glob:CustomerBundleMaintainRequest_sync_V1>

   </soapenv:Body>

</soapenv:Envelope>

Most of the times I get a success and the account gets created. But with the same data/ request sometimes it fails and I get below error:

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

   <soap:Body>

      <soap:Fault>

         <faultcode>soap:Server</faultcode>

         <faultstring xml:lang="en">RABAX occurred on server side</faultstring>

         <detail>

            <sap:Rabax xmlns:sap="http://www.sap.com/webas/710/soap/runtime/abap/fault/generic">

               <SYDATUM>20151015</SYDATUM>

               <SYUZEIT>134207</SYUZEIT>

               <ERRORCODE>DATREF_NOT_ASSIGNED</ERRORCODE>

            </sap:Rabax>

         </detail>

      </soap:Fault>

   </soap:Body>

</soap:Envelope>

Has any one faced similar issue?

Is there any way to check relevant logs in ByDesign?

Am I missing any other mandatory/ required attributes, action codes, any indicators etc.?

Your help will be appreciated.

Thanks.
