• What is the cause and solution for SAP error message RSD_TREX011 - Table '&1' already created as an index on the BWA server ?

  The SAP error message RSD_TREX011 indicates that there is an attempt to create an index on a table that has already been indexed on the BWA (Business Warehouse Accelerator) server. This can occur during the process of creating or updating an index for a data source in SAP BW.
  Cause:
  The primary cause of this error is that the index for the specified table (denoted as &1 in the error message) already exists on the BWA server. This can happen if:
  
  An index creation process was previously executed and completed successfully.
  There was an attempt to re-create the index without first dropping the existing one.
  There may be a misconfiguration or a misunderstanding of the indexing process.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check Existing Indexes:
  
  Use the BWA administration tools or transaction codes in SAP BW to check if the index for the specified table already exists.
  You can use transaction RSD1 to check the InfoObject and see if the index is listed.
  
  
  
  Drop the Existing Index:
  
  If you determine that the index is indeed present and you need to recreate it (for example, if the underlying data has changed), you can drop the existing index.
  Use the appropriate transaction or BWA administration tool to drop the index.
  
  
  
  Recreate the Index:
  
  After dropping the existing index, you can proceed to recreate the index for the table.
  Ensure that the data source is properly configured and that you are following the correct steps for index creation.
  
  
  
  Check for Errors in the Process:
  
  If the error persists, check the logs for any additional error messages or warnings that might provide more context.
  Ensure that there are no connectivity issues between the BW system and the BWA server.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to BWA and indexing for any specific guidelines or troubleshooting steps.
