How To Fix SXIVERI012 - Non-unique hash ID:&1 Type:&2 Name:&3 Namespace:&4

SAP Error Message - Details

• Message type: E = Error

• Message class: SXIVERI -

• Message number: 012

• Message text: Non-unique hash ID:&1 Type:&2 Name:&3 Namespace:&4

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

What causes this issue?

Multiple metadata entries (that is, multiple ABAP names) were found for
a WSDL key (type/name/namespace). The only way to correct this
inconsistency is to remove the incorrect metadata.
This problem can occur as a result of the following:
Proxies have been generated in different systems for the same WSDL key
(type/name/namespace), with different ABAP names resulting from the
generation procedure, and then transported to a common system.
A proxy has been generated in a subsequent system as a local object
($TMP); following this, a transport from a previous system has been
imported for the same WSDL key. -> You must delete the local object in
$TMP, see reference to report below.
Ultimately, this problem is an indication that the organizational
allocation of software components/namespaces as regards development
systems has not been adhered to.

System Response

Since a proxy is identified by the WSDL key, the assignment of the WSDL
key and proxy metadata is no longer unique, that is, it may no longer be
possible to load the metadata. Other more severe side effects cannot be
ruled out.

How to fix this error?

Case 1: You must delete one of the two proxies in its original system by
using transaction SPROXY. You must transport the deletion to the
subsequent system.
Case 2: You can use report
<DS:REPO.SXIVERI_PROXY_HASHID_CHECK>SXIVERI_PROXY_HASHID_CHECK</> to
find the affected objects and then delete the respective "wrong" proxy
locally.

• What is the cause and solution for SAP error message SXIVERI012 - Non-unique hash ID:&1 Type:&2 Name:&3 Namespace:&4 ?

  The SAP error message SXIVERI012 indicates that there is a non-unique hash ID in the system. This typically occurs when there are multiple objects (like function modules, classes, or other repository objects) that have the same hash ID, which is used by SAP to uniquely identify objects in the system.
  Cause:
  The error can be caused by several factors, including:
  
  Duplicate Objects: There may be duplicate objects in the system that have the same name or content, leading to the same hash ID being generated for them.
  Transport Issues: If objects were transported incorrectly or if there are inconsistencies in the transport directory, it can lead to hash ID conflicts.
  Development Errors: Custom developments or modifications that inadvertently create duplicate objects can also trigger this error.
  
  Solution:
  To resolve the SXIVERI012 error, you can follow these steps:
  
  
  Identify Duplicates:
  
  Use transaction codes like SE80 (Object Navigator) or SE11 (Data Dictionary) to search for objects with the same name or type.
  Check the namespace and ensure that there are no conflicting objects.
  
  
  
  Check Transport Requests:
  
  Review the transport requests to ensure that objects were transported correctly and that there are no duplicates in the transport directory.
  If necessary, re-import the transport requests or correct any inconsistencies.
  
  
  
  Delete or Rename Duplicates:
  
  If you find duplicate objects, you may need to delete or rename them to resolve the conflict.
  Ensure that you have backups and that you are following your organization's change management procedures before making any deletions.
  
  
  
  Check for Modifications:
  
  If the error is related to custom developments, review the code and modifications to ensure that they do not create conflicts with standard SAP objects.
  
  
  
  Consult SAP Notes:
  
  Check the SAP Support Portal for any relevant SAP Notes that may address this specific error or provide additional guidance.
  
  
  
  System Consistency Check:
  
  Run consistency checks in the system to identify any other potential issues that may be causing the error.
  
  
  
  Related Information:
  
  Transaction Codes: SE80, SE11, SE37 (for function modules), SE24 (for classes).
  SAP Notes: Always check for relevant SAP Notes that may provide specific fixes or workarounds for this error.
  Documentation: Review SAP documentation related to object management and transport management for best practices.
