• What is the cause and solution for SAP error message RSCV526 - ORACLE: No degenerated indexes were found for InfoCube &1. ?

  The SAP error message RSCV526 ORACLE: No degenerated indexes were found for InfoCube &1 typically occurs in the context of SAP BW (Business Warehouse) when there is an issue with the database indexes related to an InfoCube. This error indicates that the system is unable to find any degenerated indexes for the specified InfoCube, which can affect performance and data retrieval.
  Cause:
  
  Missing Degenerated Indexes: Degenerated indexes are special types of indexes that are used in SAP BW to optimize query performance. If these indexes are missing or not properly configured, the system will throw this error.
  Database Configuration Issues: There may be issues with the underlying Oracle database configuration or the way the InfoCube is set up.
  Data Model Changes: Changes in the data model or InfoCube structure may lead to inconsistencies in the indexes.
  Transport Issues: If the InfoCube was transported from one system to another, the indexes may not have been properly created or activated.
  
  Solution:
  
  
  Check Index Configuration:
  
  Go to the InfoCube in the SAP BW system and check the index settings. Ensure that the degenerated indexes are defined and activated.
  You can do this through transaction RSA1 (Data Warehousing Workbench) and navigating to the InfoCube.
  
  
  
  Rebuild Indexes:
  
  If the indexes are missing, you may need to rebuild them. This can typically be done by executing the Manage Indexes function in the InfoCube settings.
  You can also use transaction RSCUSTV10 to check and adjust the settings related to indexes.
  
  
  
  Check for Data Model Changes:
  
  If there have been recent changes to the InfoCube structure, ensure that all necessary adjustments have been made to the indexes.
  You may need to re-activate the InfoCube to ensure that all components are correctly configured.
  
  
  
  Transport Issues:
  
  If the InfoCube was transported, check the transport logs for any errors related to the indexes.
  You may need to manually create or adjust the indexes in the target system.
  
  
  
  Database Maintenance:
  
  Perform regular database maintenance tasks, such as analyzing and optimizing the database, to ensure that the indexes are functioning correctly.
