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.
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.
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.
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.

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
