• What is the cause and solution for SAP error message RSDRD454 - Shadow table &1 created for table &2 ?

  The SAP error message RSDRD454 indicates that a shadow table has been created for a specific table in the context of SAP BW (Business Warehouse) or SAP HANA. This message typically arises during the data loading process or when there are issues with the data model.
  Cause:
  The creation of a shadow table usually occurs due to one of the following reasons:
  
  
  Data Consistency Issues: The system detected inconsistencies in the data or metadata of the original table, prompting the creation of a shadow table to ensure data integrity during processing.
  
  
  Performance Optimization: In some cases, shadow tables are created to optimize performance for certain operations, especially when dealing with large datasets.
  
  
  Data Load Failures: If a data load process fails, the system may create a shadow table to allow for recovery or to continue processing without affecting the original table.
  
  
  Changes in Data Model: If there are changes in the data model (like changes in InfoObjects or InfoProviders), the system may create a shadow table to accommodate these changes.
  
  
  Solution:
  To resolve the issue indicated by the RSDRD454 message, you can take the following steps:
  
  
  Check the Shadow Table: Investigate the shadow table that has been created. You can do this by checking the database or using transaction codes like RSA1 (Data Warehousing Workbench) to analyze the InfoProvider.
  
  
  Analyze Data Load Logs: Review the data load logs to identify any errors or warnings that may have triggered the creation of the shadow table. This can provide insights into what went wrong during the data load process.
  
  
  Repair Data Consistency: If the issue is related to data consistency, you may need to repair the inconsistencies. This could involve reloading data, correcting data in the source system, or adjusting the data model.
  
  
  Delete Shadow Table: If the shadow table is no longer needed and the original table is consistent, you can delete the shadow table. However, ensure that you have resolved any underlying issues before doing this.
  
  
  Consult SAP Notes: Check for any relevant SAP Notes or documentation that may provide additional guidance or solutions specific to your version of SAP BW or HANA.
  
  
  Contact SAP Support: If the issue persists or if you are unsure about the steps to take, consider reaching out to SAP Support for assistance.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as RSA1 (Data Warehousing Workbench), RSD1 (InfoObject Maintenance), and RSMO (Monitor Data Load) for monitoring and managing data loads.
  SAP BW Documentation: Review SAP BW documentation for best practices on data loading and handling shadow tables.
  Performance Tuning: Consider performance tuning strategies for your BW system to minimize the need for shadow tables in the future.
  
  By following these steps, you should be able to address the RSDRD454 error message effectively.
