• What is the cause and solution for SAP error message RSD_TREX201 - Select one or more BWA indexes ?

  The SAP error message RSD_TREX201, which indicates "Select one or more BWA indexes," typically occurs in the context of SAP BW (Business Warehouse) when there is an issue related to the configuration or usage of the BWA (Business Warehouse Accelerator) indexes. This error can arise when a user attempts to execute a query or perform an operation that requires the selection of BWA indexes, but none are selected or available.
  Cause:
  
  No BWA Indexes Available: The most common cause of this error is that there are no BWA indexes created for the InfoProvider or the query being executed.
  Incorrect Configuration: The BWA might not be properly configured or connected to the BW system.
  Data Model Changes: Changes in the data model or InfoProvider might have led to the unavailability of the BWA indexes.
  Authorization Issues: The user may not have the necessary authorizations to access the BWA indexes.
  
  Solution:
  
  
  Check BWA Indexes:
  
  Go to the transaction code RSD1 (InfoProvider maintenance) and check if BWA indexes are created for the relevant InfoProvider.
  If no indexes are available, you may need to create them.
  
  
  
  Create BWA Indexes:
  
  If indexes are missing, you can create them by navigating to the relevant InfoProvider and selecting the option to create BWA indexes. This usually involves running the "Create BWA Index" process.
  
  
  
  Check BWA Configuration:
  
  Ensure that the BWA is properly configured and connected to your BW system. This can be checked in the BWA administration tools or through the BW system settings.
  
  
  
  Data Load:
  
  Ensure that the data has been loaded into the InfoProvider. If the data is not loaded, the BWA index may not be created.
  
  
  
  User Authorizations:
  
  Verify that the user executing the query has the necessary authorizations to access the BWA indexes. This may involve checking roles and permissions in the SAP system.
  
  
  
  Rebuild Indexes:
  
  If the indexes are present but still causing issues, consider rebuilding them. This can sometimes resolve inconsistencies or corruption in the indexes.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as RSD1 (InfoProvider maintenance), RSD3 (Data Warehousing Workbench), and RSBWA (BWA Administration).
  SAP Notes: Check for any relevant SAP Notes that may address specific issues related to BWA and the RSD_TREX201 error.
  Documentation: Review SAP documentation on BWA and BW performance optimization for best practices and troubleshooting steps.
