How To Fix ESH_OM_OBJ_MODEL_REP648 - &1 "&2" in SWC &3 has same name as in SWC &4. Rename manually

SAP Error Message - Details

• Message type: E = Error

• Message class: ESH_OM_OBJ_MODEL_REP - Object Model Repository

• Message number: 648

• Message text: &1 "&2" in SWC &3 has same name as in SWC &4. Rename manually

What causes this issue?

At least two software components contain objects with the same name and
you have established or want to establish a relationship between the
software components. Alternatively, you want to use objects from the two
software components together at runtime (for example, by creating search
connectors). The object type name specified is not unique within the set
of object models.
The naming conflict can arise due to the following situations:
Object types have been delivered or imported. The software component
that the objects have been imported to is used together with a software
component containing an object with the same name.
You have created a new hierarchical dependency between previously
uncorrelated software components that contain object types with the same
name.
Parallel runtime usage of software components containing object types
with the same name within the same logical system.

System Response

The object name has to be unique. As long as there are unresolved naming
conflicts within the hierarchy of software components or within the set
of software components simultaneously assigned to the same logical
system, the software components cannot be used together at runtime. The
conflicts appear in the Enterprise Search object modeler or during
connector creation.

How to fix this error?

You must resolve the naming conflict.
Solution options:
Rename the object type in one of the software components mentioned.
Note: Before you rename the object type, check whether data providers,
such as BADI implementations for custom data extraction, are used by the
object type. Ensure that all places that refer to the object type name
are adjusted accordingly.
Alternatively, if the object types are physically identical copies, you
can delete one of them.
<ZK>Example: </>
The object type SERVICE_DOCUMENTS is reported to exist twice.
To resolve the naming conflict, you have to rename the object type in
one of the affected software components or delete one of them. Suppose
you decide to rename the object in your own model to
SERVICE_DOCUMENTS_1.
If possible, you should rename the objects in your development system
and transport the new name within your system landscape.
Suppose the object SERVICE_DOCUMENTS uses a data extractor service (for
example CL_SERVICE_DOC_EXTRACTOR), which is implemented as a BADI
instantiation with a filter on the object type name SERVICE_DOCUMENTS.
In this case, you have to change the BADI filter to SERVICE_DOCUMENTS_1
and also transport this change within your system landscape.
After renaming object types, you must create the search connectors
again.

• What is the cause and solution for SAP error message ESH_OM_OBJ_MODEL_REP648 - &1 "&2" in SWC &3 has same name as in SWC &4. Rename manually ?

  The SAP error message ESH_OM_OBJ_MODEL_REP648 indicates a naming conflict in the context of the SAP Enterprise Search (ESH) or the Object Model. This error typically arises when there are two objects (like a search model or a component) with the same name in different Software Components (SWCs). 
  Cause:
  The error occurs because:
  
  Two different software components (SWCs) contain objects with the same name, which leads to ambiguity in the system.
  This can happen during the development or transport of objects between different systems or environments.
  
  Solution:
  To resolve this error, you need to manually rename one of the conflicting objects. Here are the steps you can follow:
  
  
  Identify the Conflicting Objects: 
  
  The error message provides the names of the conflicting objects and the SWCs they belong to. 
  For example, if the message states that object "&1" in SWC "&3" has the same name as in SWC "&4", you need to note down these details.
  
  
  
  Access the Object in the Development Environment:
  
  Use the SAP GUI or the relevant transaction code (like SE80 for Object Navigator) to locate the conflicting objects in both SWCs.
  
  
  
  Rename One of the Objects:
  
  Choose one of the objects to rename. Ensure that the new name adheres to your organization's naming conventions and is unique within the context of the SWC.
  You can rename the object directly in the development environment. Make sure to update any references to this object in your code or configuration.
  
  
  
  Transport Changes:
  
  After renaming, transport the changes to the relevant systems (if applicable) to ensure consistency across environments.
  
  
  
  Test the Changes:
  
  After renaming and transporting, test the functionality to ensure that everything works as expected and that the error no longer appears.
  
  
  
  Related Information:
  
  Documentation: Check SAP Help Portal or relevant SAP Notes for more information on naming conventions and best practices for object management in ESH.
  Version Compatibility: Ensure that the versions of the software components are compatible, as sometimes naming conflicts can arise from version mismatches.
  Consult with Team: If you are working in a team, consult with your colleagues or the development team to ensure that the renaming does not affect other parts of the application.
  
  By following these steps, you should be able to resolve the ESH_OM_OBJ_MODEL_REP648 error effectively.
