• What is the cause and solution for SAP error message RSDD_ZA394 - Delete BWA indexes or enlarge your BWA installation ?

  The SAP error message RSDD_ZA394 typically occurs in the context of SAP BW (Business Warehouse) when there is an issue with the BWA (Business Warehouse Accelerator) indexes. This error indicates that the BWA indexes are either full or that the BWA installation does not have enough capacity to accommodate the data being processed.
  Cause:
  
  Full BWA Indexes: The BWA indexes may have reached their maximum capacity, which prevents new data from being indexed.
  Insufficient BWA Installation Size: The current BWA installation may not have enough resources (memory, disk space) to handle the volume of data being processed.
  Data Volume Increase: An increase in the volume of data being loaded into the BW system can lead to the existing BWA indexes becoming insufficient.
  
  Solution:
  
  
  Delete Unused BWA Indexes:
  
  Identify and delete any unused or obsolete BWA indexes. This can free up space for new indexes.
  Use transaction code RSD1 to manage InfoProviders and check for indexes that can be deleted.
  
  
  
  Enlarge BWA Installation:
  
  If deleting indexes does not resolve the issue, consider enlarging your BWA installation. This may involve increasing the hardware resources (CPU, memory, disk space) allocated to the BWA.
  Consult with your system administrator or SAP Basis team to assess the current BWA configuration and determine the necessary upgrades.
  
  
  
  Rebuild BWA Indexes:
  
  In some cases, rebuilding the BWA indexes can help. This can be done through the BW administration tools.
  
  
  
  Monitor BWA Usage:
  
  Regularly monitor the usage of BWA indexes and the overall performance of the BWA system to prevent future occurrences of this error.
