  The SAP error message RSD_TREX067 indicates that there is an issue with the combination of a delta index and a main index in the context of SAP BW (Business Warehouse) or SAP HANA. This error typically arises during the process of data loading or when trying to activate a delta index that is supposed to be combined with its corresponding main index.
  Causes:
  
  Inconsistent Data: The delta index may contain data that is inconsistent with the main index, possibly due to failed data loads or issues during the extraction process.
  Index Corruption: The main index or delta index may be corrupted, leading to an inability to combine them.
  Locking Issues: There may be locks on the indexes that prevent the delta index from being combined with the main index.
  Configuration Issues: Incorrect settings in the data source or in the InfoProvider can lead to this error.
  System Performance: If the system is under heavy load, it may not be able to process the combination of indexes in a timely manner.
  
  Solutions:
  
  Check Data Consistency: Verify the consistency of the data in the delta and main indexes. You can do this by running consistency checks or reloading the data.
  Rebuild Indexes: If corruption is suspected, consider rebuilding the main and delta indexes. This can often resolve issues related to index corruption.
  Release Locks: Check for any locks on the indexes and release them if necessary. You can use transaction codes like SM12 to view and manage locks.
  Review Configuration: Ensure that the configuration settings for the data source and InfoProvider are correct. This includes checking the extraction settings and ensuring that the delta mechanism is properly configured.
  Monitor System Performance: If the system is under heavy load, consider scheduling the data load during off-peak hours or optimizing the performance of the system.
