Smart SAP Assistant

• What is the cause and solution for SAP error message 0K023 - Source and target client are identical, so import is not possible ?

  The SAP error message 0K023 indicates that the source and target clients are identical, which means that you are trying to import data from one client to another client that is the same. This situation is not allowed because it would not make sense to import data into the same client from itself.
  Cause:
  
  You are attempting to perform a client import (e.g., using transaction STMS or SCC1) where the source client and the target client are the same.
  This can happen if you mistakenly select the same client for both the source and target during the import process.
  
  Solution:
  
  
  Check Client Selection: Ensure that you are selecting different clients for the source and target. The source client should be the one from which you want to export data, and the target client should be the one into which you want to import the data.
  
  
  Correct the Import Process:
  
  If you are using transaction SCC1, make sure to specify a different target client.
  If you are using transport management system (TMS), verify the transport request and ensure that the target client is correctly set.
  
  
  
  Review Transport Requests: If you are working with transport requests, ensure that the transport request is meant for the correct target client and that it is not mistakenly set to the same client.
  
  
  Consult Documentation: If you are unsure about the import process, refer to SAP documentation or consult with your SAP Basis team for guidance on how to properly perform client imports.
  
  
  Related Information:
  
  Client Concept in SAP: SAP systems are organized into clients, which are separate environments within the same system. Each client can have its own data and configuration.
  Transport Management System (TMS): TMS is used to manage the transport of objects between different SAP systems or clients. Understanding how TMS works can help prevent such errors.
  Client Copy: If you need to copy data from one client to another, consider using the client copy functionality (SCCL for local client copy or SCC9 for remote client copy) instead of an import.
  
  By ensuring that the source and target clients are different, you should be able to resolve the error and proceed with your import successfully.
