• What is the cause and solution for SAP error message RSAR555 - RSOLOGSYSMAP: Previously &1 -> &2, now &3 -> &4 ?

  The SAP error message RSAR555 is related to the Data Warehousing component of SAP, specifically in the context of the SAP BW (Business Warehouse) system. This error typically occurs when there is a mismatch or inconsistency in the mapping of log systems in the SAP BW system.
  Cause:
  The error message RSAR555 indicates that there has been a change in the mapping of the source system. The message format suggests that the system is trying to inform you that the previous mapping of a source system (from &1 to &2) has changed to a new mapping (from &3 to &4). This can happen due to various reasons, such as:
  
  Changes in Source System Configuration: The source system configuration might have been altered, leading to a change in the logical system name or the way it is mapped in BW.
  Transport Issues: If changes were transported from one system to another (e.g., from development to production), inconsistencies might arise if the transport was not executed correctly.
  Data Source Changes: Changes in the data source configuration or the underlying data model can also lead to this error.
  
  Solution:
  To resolve the RSAR555 error, you can follow these steps:
  
  
  Check Source System Configuration:
  
  Go to the SAP BW system and check the configuration of the source systems in transaction RSA1 (Data Warehousing Workbench).
  Ensure that the logical system names are correctly defined and that they match the expected values.
  
  
  
  Review Transport Requests:
  
  If the issue arose after a transport, review the transport logs to ensure that all necessary objects were transported correctly.
  Check if any objects were missed or if there were any errors during the transport process.
  
  
  
  Update the Mapping:
  
  If the mapping has changed intentionally, update the relevant settings in the BW system to reflect the new mappings.
  You can do this in the RSA1 transaction under the "Source Systems" section.
  
  
  
  Check Data Sources:
  
  Verify the data sources that are using the affected source systems. Ensure that they are correctly configured and that the mappings are consistent.
  
  
  
  Re-activate Data Sources:
  
  Sometimes, re-activating the data sources can help resolve inconsistencies. You can do this in the RSA1 transaction.
  
  
  
  Consult SAP Notes:
  
  Check for any relevant SAP Notes that might address this specific error or provide additional guidance.
