• What is the cause and solution for SAP error message RSAOLTP456 - No authorization to replicate: DataSource &1 from source system &2 ?

  The SAP error message RSAOLTP456 indicates that there is no authorization to replicate a specific DataSource from a source system. This error typically occurs in the context of SAP BW (Business Warehouse) when trying to replicate data from an OLTP (Online Transaction Processing) system.
  Cause:
  The error can be caused by several factors, including:
  
  
  Missing Authorizations: The user account being used to perform the replication does not have the necessary authorizations to access the DataSource in the source system.
  
  
  Incorrect User Mapping: The user mapping between the BW system and the source system may not be set up correctly, leading to authorization issues.
  
  
  DataSource Configuration: The DataSource itself may not be properly configured or may have restrictions that prevent access.
  
  
  Transport Issues: If the DataSource was recently transported from another system, there may be issues with the transport that affect authorization.
  
  
  Solution:
  To resolve the RSAOLTP456 error, you can take the following steps:
  
  
  Check User Authorizations:
  
  Ensure that the user has the necessary authorizations in the source system to access the DataSource. This typically involves checking the roles and authorizations assigned to the user in the source system.
  Use transaction code SU53 in the source system to analyze the authorization check after the error occurs. This will show you which authorizations are missing.
  
  
  
  User Mapping:
  
  Verify the user mapping between the BW system and the source system. This can be done in the BW system using transaction RSA1 (Data Warehousing Workbench) and navigating to the "Source Systems" section.
  Ensure that the user in the BW system is correctly mapped to a user in the source system that has the necessary authorizations.
  
  
  
  DataSource Configuration:
  
  Check the configuration of the DataSource in the source system. Ensure that it is active and that there are no restrictions on access.
  You can use transaction RSA1 in the BW system to check the status of the DataSource.
  
  
  
  Transport Issues:
  
  If the DataSource was recently transported, check the transport logs for any errors or warnings that may indicate issues with the transport.
  Ensure that all necessary objects related to the DataSource have been transported correctly.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to the specific DataSource and its authorization requirements. There may be specific notes that address common issues with that DataSource.

  SAP Notes: Check for relevant SAP Notes in the SAP Support Portal that may provide additional guidance or fixes related to this error.
  
  
  Authorization Objects: Familiarize yourself with the relevant authorization objects that control access to DataSources, such as S_BW_AUTH and S_BW_DATA.
  
  
  By following these steps, you should be able to identify and resolve the authorization issue causing the RSAOLTP456 error.
