How To Fix RSD_TREX213 - Index for table '&1' set to delta mode

SAP Error Message - Details

• Message type: E = Error

• Message class: RSD_TREX - Messages from TREX Aggregate Area

• Message number: 213

• Message text: Index for table '&1' set to delta mode

What causes this issue?

The delta mode was set for the selected index. In this case, after the
next rollup or change run in which new data is written to this index,
the data is written to a delta index. In this way, the write processes
are to some degree considerably shortened, but the read access times are
increased. The read times get worse the larger the delta index.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Combine the delta indexes with your main index regularly in a separate
process. To do this, schedule the process or the program "R
SDDTREX_DELTAINDEX_MERGE" .

• What is the cause and solution for SAP error message RSD_TREX213 - Index for table '&1' set to delta mode ?

  The SAP error message RSD_TREX213 indicates that the index for a specific table has been set to delta mode. This typically occurs in the context of SAP BW (Business Warehouse) and is related to the indexing of InfoProviders, particularly when using the TREX search engine for full-text search capabilities.
  Cause:
  The error message is triggered when the system detects that the index for a particular InfoProvider (like an InfoCube or DataStore Object) is in delta mode. Delta mode is used to handle incremental data loads, meaning that only changes (new or modified records) are indexed rather than the entire dataset. This can happen due to:
  
  Incomplete Indexing: The initial indexing process may not have been completed successfully.
  Data Load Issues: There may have been issues during the data load process that caused the index to be set to delta mode.
  Configuration Settings: The InfoProvider may have been configured to operate in delta mode for performance reasons.
  
  Solution:
  To resolve the RSD_TREX213 error, you can follow these steps:
  
  
  Rebuild the Index:
  
  Go to the SAP BW system and navigate to the relevant InfoProvider.
  Trigger a full re-indexing of the InfoProvider. This can usually be done through the administration or maintenance transaction for the InfoProvider.
  In the case of an InfoCube, you can use transaction RSD1 to access the InfoCube and then choose the option to rebuild the index.
  
  
  
  Check Data Load Processes:
  
  Review the data load processes to ensure that they are completing successfully without errors.
  If there are errors in the data load, resolve those issues first before attempting to re-index.
  
  
  
  Monitor and Adjust Settings:
  
  Check the settings for the InfoProvider to see if delta mode is appropriate for your use case. If not, consider switching to full mode if it aligns with your performance and data requirements.
  
  
  
  Consult Logs:
  
  Review the logs for any additional error messages or warnings that may provide more context on why the index is in delta mode.
  
  
  
  SAP Notes and Documentation:
  
  Check for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps. SAP Notes can be found in the SAP Support Portal.
  
  
  
  Related Information:
  
  TREX: TREX (Text Retrieval and Extraction) is a search engine used in SAP for full-text search capabilities. Understanding how TREX works and its configuration can help in troubleshooting related issues.
  InfoProviders: Familiarize yourself with the different types of InfoProviders in SAP BW, such as InfoCubes, DataStore Objects (DSOs), and MultiProviders, as the indexing behavior may vary.
  Performance Considerations: Delta indexing can improve performance for large datasets, but it may require careful management to ensure that the indexes remain consistent and up-to-date.
  
  By following these steps, you should be able to resolve the RSD_TREX213 error and ensure that your InfoProvider is indexed correctly.
