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.
