SAP Error Message - Details

• Message type: E = Error

• Message class: EA - IDoc Basis Messages

• Message number: 728

• Message text: IDoc SOAP Namespace - Violation (&)

What causes this issue?

This IDoc was sent using the SOAP protocol, with the namespace <ZH>
'urn:sap-com:document:sap:idoc:soap:messages'</> used for the SOAP
request.
The following rules apply to this namespace:
A SOAP request can contain one IDoc only and you cannot send multiple
IDocs in a single request.
A system can receive each IDoc only once ("Exactly Once" behavior). This
is guaranteed by using a unique message ID, passed in the field <LS>
ARCKEY</> (ID, key of the EDI archive) of the control record. The
message ID must contain the prefix <ZH>'urn:sap.com:msgid='</>.
The rules above were violated as follows: (&v1&).
Possible error situations:
<ZH>MULTIPLE_IDOCS_NOT_ALLOWED</> The SOAP request contains multiple
IDocs.
<ZH>SOAP_MSGID_INITIAL</> The message ID is missing in the control
record.
<ZH>SOAP_MSGID_PREFIX_INVALID</> The message ID does not contain the
requested prefix.
<ZH>MSGID_LOCKED</> The processing of an IDoc with the same message ID
was already started by another call.

System Response

The IDoc was not accepted by the receiver system.

• What is the cause and solution for SAP error message EA728 - IDoc SOAP Namespace - Violation (&) ?

  The SAP error message EA728, which indicates a "IDoc SOAP Namespace - Violation," typically occurs when there is a mismatch or violation in the expected SOAP namespace for IDocs being processed in an SAP system. This can happen in scenarios where IDocs are being sent or received via web services, particularly when using the SOAP protocol.
  Cause:
  
  Namespace Mismatch: The IDoc being processed does not conform to the expected SOAP namespace defined in the service interface. This can happen if the IDoc structure has been changed or if the wrong version of the IDoc is being used.
  Incorrect Configuration: The configuration settings for the IDoc interface may not be set up correctly, leading to a mismatch in the expected namespaces.
  Versioning Issues: If there are multiple versions of the IDoc or service interface, using an outdated version can lead to namespace violations.
  Data Format Issues: The data being sent in the IDoc may not be formatted correctly according to the expected schema, leading to namespace errors.

  Check Namespace Configuration: Verify the namespace configuration in the SAP system. Ensure that the IDoc type and the associated namespaces are correctly defined in the relevant configuration settings.
  Validate IDoc Structure: Ensure that the IDoc being sent or received matches the expected structure and version. You can use transaction WE60 to check the IDoc documentation and structure.
  Review SOAP Interface: If you are using a web service, check the WSDL (Web Services Description Language) file to ensure that the namespaces defined there match those expected by the IDoc.
  Update IDoc Version: If there are multiple versions of the IDoc, ensure that the correct version is being used in the communication.
  Test with Sample Data: Use sample data that is known to work with the IDoc to test the interface and identify if the issue is with the data being sent.
  Check Middleware Configuration: If you are using middleware (like SAP PI/PO or other integration tools), ensure that the mappings and configurations are set up correctly to handle the namespaces.
  
  Related Information:
  
  Transaction Codes: Use transaction WE02 or WE05 to monitor IDoc processing and check for errors.
