• What is the cause and solution for SAP error message RSD_TREX087 - At least one large index must be created for the BWA index ?

  The SAP error message RSD_TREX087 indicates that at least one large index must be created for the BWA (Business Warehouse Accelerator) index. This error typically arises when you are trying to create or manage BWA indexes in SAP BW and the system requires a large index to be created for optimal performance.
  Cause:
  
  Index Configuration: The BWA system requires at least one large index to be created for efficient data retrieval and processing. If no large index is defined or if the existing indexes do not meet the required criteria, this error will occur.
  Data Volume: The volume of data being processed may necessitate a large index to ensure that queries can be executed efficiently.
  Index Type: The type of index being created may not be suitable for the data model or the query requirements.
  
  Solution:
  To resolve the RSD_TREX087 error, you can follow these steps:
  
  
  Create a Large Index:
  
  Go to the BWA administration or the relevant transaction in SAP BW.
  Identify the InfoProvider for which you need to create the index.
  Create a large index for the InfoProvider. This can typically be done through the BWA administration interface or by using the relevant transaction codes (like RSA1 for Data Warehousing Workbench).
  Ensure that the index is configured to handle the expected data volume.
  
  
  
  Check Existing Indexes:
  
  Review the existing indexes to ensure that at least one is marked as a large index.
  If necessary, delete or modify existing indexes to meet the requirements.
  
  
  
  Monitor Data Volume:
  
  Assess the data volume and ensure that it aligns with the index configuration. If the data volume has increased significantly, you may need to adjust your indexing strategy.
  
  
  
  Rebuild Indexes:
  
  If you have made changes to the data model or the underlying data, consider rebuilding the indexes to ensure they are optimized for the current data structure.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to BWA and indexing for specific guidelines and best practices.
