What causes this issue?

A category has an internal key (which is a GUID) and an external key
(its name you can see in the Enterprise Search Modeler), When you create
a new category or rename an existing category the combination of the
internal and the external key is stored on the GTABKEY-server to assure
that a category has the same internal key in different systems.
During the creation of category &v1& it was detected that there is
already an according entry on the GTABKEY-server.
This means either that
a category with the name &v1& already exists in at least one other
system/client (e.g. in a lower release) or
that in this or in another system/client a category with the name &v1&
had and was deleted.

System Response

How to fix this error?

Please be aware that in case 1. the new category &v1& is the same as the
other categories that exist in other systems/clients.

• What is the cause and solution for SAP error message ESH_OM_OBJ_MODEL_RP2624 - Category &1 already existed or exists in another system/client ?

  The SAP error message ESH_OM_OBJ_MODEL_RP2624 indicates that there is a conflict with the object model category you are trying to create or modify. Specifically, it suggests that the category you are attempting to use already exists in the system or in another client. This can occur in various scenarios, such as when importing data, configuring object models, or during system migrations.
  Cause:
  
  Duplicate Category: The category you are trying to create already exists in the same system or in another client within the same SAP landscape.
  Transport Issues: If you are transporting objects between systems, the category may have been transported already, leading to a conflict.
  Client-Specific Data: The category might exist in a different client, and the system is enforcing uniqueness across clients.
  
  Solution:
  
  
  Check Existing Categories: 
  
  Use transaction codes like SE11 (Data Dictionary) or SE80 (Object Navigator) to check if the category already exists in the system.
  You can also use the relevant transaction for the specific object model you are working with to see if the category is listed.
  
  
  
  Modify or Delete Existing Category:
  
  If the category exists and is not needed, consider deleting it or modifying it to avoid the conflict.
  Ensure that you have the necessary authorizations to make changes.
  
  
  
  Use a Different Name:
  
  If the category is required and cannot be deleted, consider using a different name for the new category you are trying to create.
  
  
  
  Transport Management:
  
  If this issue arises during a transport, check the transport logs to see if the category was included in a previous transport.
  Ensure that the transport requests are correctly managed and that there are no conflicts.
  
  
  
  Client-Specific Considerations:
  
  If you are working in a multi-client environment, ensure that you are aware of the categories that exist in other clients and avoid naming conflicts.
