How To Fix TR323 - Namespace for object type &2 overlaps with other namespaces

SAP Error Message - Details

• Message type: E = Error

• Message class: TR - Change and Transport System

• Message number: 323

• Message text: Namespace for object type &2 overlaps with other namespaces

What causes this issue?

The namespaces in the Transport Organizer and ABAP Workbench are
defined differently: the distinction of transport object types in the
Transport Organizer does not always mean the objects are stored
separately in the ABAP Workbench.
The namespace for the object type &V1& &V2& in the ABAP Workbench
overlaps with the namespace of other object types.
A reservation can therefore not prevent the namespace from being used
for other object types, but can only ensure a standard assignment of
all objects of the specified object type to your package.
The following object types have completely or partly the same
namespaces in the Repository of the ABAP Workbench:
DTEL data elements
TABL tables
TTYP Dictionary table type
VIEW views
CLAS ABAP objects classes

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

<ZH>Example</>
You reserve a data element name range to use in the package of your
project. If a developer in another project now creates a table using
the same naming convention, this name is no longer available for
creating a data element despite the reservation.

System Response

How to fix this error?

To ensure exclusive reservation of a name range, you must make an
identical reservation entry for all transport object types specified.

• What is the cause and solution for SAP error message TR323 - Namespace for object type &2 overlaps with other namespaces ?

  The SAP error message TR323 indicates that there is a conflict with the namespace for a specific object type in the SAP system. This typically occurs when you are trying to create or modify an object (like a transport request, program, or other development objects) that falls under a namespace that overlaps with another existing namespace. 
  Cause:
  
  Namespace Conflict: The error arises when the namespace you are trying to use for your object is already in use by another object or is reserved for a different purpose.
  Incorrect Configuration: The system may have been incorrectly configured, leading to overlapping namespaces.
  Transport Layer Issues: If you are working in a transport layer that has conflicting namespaces, this error can occur.
  
  Solution:
  
  Check Existing Namespaces: Review the existing namespaces in your SAP system to identify any conflicts. You can do this by using transaction codes like SE03 (Transport Organizer Tools) or SE80 (Object Navigator).
  Change Namespace: If you find that the namespace you are trying to use is already taken, consider changing your object to use a different, available namespace.
  Consult with Basis Team: If you are unsure about the namespaces or how to resolve the conflict, consult with your SAP Basis team or system administrator. They can provide insights into the configuration and help you find a suitable namespace.
  Review Transport Requests: If the issue is related to transport requests, ensure that the transport requests are correctly configured and do not overlap with other requests.
  Documentation: Refer to SAP documentation or notes related to namespaces and transport management for further guidance.
  
  Related Information:
  
  Namespaces: In SAP, namespaces are used to organize and manage objects. They help avoid naming conflicts and ensure that objects are uniquely identifiable.
  Transport Management System (TMS): The TMS is responsible for managing the transport of objects between different SAP systems (e.g., development, quality assurance, production). Proper configuration of TMS is crucial to avoid namespace conflicts.
  SAP Notes: Check SAP Notes for any known issues or updates related to namespace management and transport requests. You can search for relevant notes in the SAP Support Portal.
  
  By following these steps, you should be able to resolve the TR323 error and successfully manage your SAP objects without namespace conflicts.
