• What is the cause and solution for SAP error message NRSCNV404 - Secondary indexes of tables of InfoCube &1 could not be re-created ?

  The SAP error message NRSCNV404 indicates that there was an issue with the re-creation of secondary indexes for the specified InfoCube. This error typically occurs during the process of data loading or when performing certain administrative tasks related to InfoCubes in SAP BW (Business Warehouse).
  Cause:
  The error can be caused by several factors, including:
  
  
  Data Consistency Issues: There may be inconsistencies in the data or metadata of the InfoCube that prevent the secondary indexes from being created or updated.
  
  
  Database Issues: Problems with the underlying database, such as locks, corruption, or insufficient resources, can lead to this error.
  
  
  Configuration Issues: Incorrect settings or configurations in the InfoCube or related objects may prevent the successful creation of secondary indexes.
  
  
  Missing or Incomplete Data: If the data being loaded into the InfoCube is incomplete or missing key fields, it can lead to issues when trying to create secondary indexes.
  
  
  System Performance: If the system is under heavy load or if there are performance issues, it may not be able to complete the index creation process.
  
  
  Solution:
  To resolve the NRSCNV404 error, you can take the following steps:
  
  
  Check Data Consistency:
  
  Use transaction codes like RSA1 to check the status of the InfoCube and ensure that there are no inconsistencies.
  Run the consistency check for the InfoCube using transaction RSCNV_CHECK.
  
  
  
  Rebuild Indexes:
  
  You can manually attempt to rebuild the secondary indexes. This can be done using transaction RSA1, navigating to the InfoCube, and selecting the option to rebuild indexes.
  
  
  
  Check Database Logs:
  
  Review the database logs for any errors or warnings that may indicate underlying issues with the database.
  
  
  
  Monitor System Performance:
  
  Check system performance metrics to ensure that the system is not overloaded. If necessary, schedule the index creation during off-peak hours.
  
  
  
  Review InfoCube Configuration:
  
  Ensure that the InfoCube is correctly configured and that all necessary fields are present and correctly defined.
