How To Fix RSD_TREX517 - Check tables against index contents (for all types)

SAP Error Message - Details

• Message type: E = Error

• Message class: RSD_TREX - Messages from TREX Aggregate Area

• Message number: 517

• Message text: Check tables against index contents (for all types)

Description
<ZH>Check Table Index Contents:</> This test compares the contents of
each individual table with the contents of the corresponding index
record-by-record. This check is only suitable for tables or indexes that
do not have large amounts of data, such as dimension tables, some master
data tables, but generally not fact tables. If a table contains 10,000
records or more, it is not checked.
Repair
If the check shows differences in the tables, this does not necessarily
mean that the SAP NetWeaver BW Accelerator index is incorrect. In some
situations, the content of the indexes of the BW Accelerator index may
differ from the content of the corresponding database table, but the
data is still correct. This may be the case if requests have been
deleted from the InfoCube or if an InfoCube has been compressed.
Perform another analysis, for example, with an additional consistency
check. Only then should you rebuild the BW Accelerator index and rebuild
the master data tables individually, as required.

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

• What is the cause and solution for SAP error message RSD_TREX517 - Check tables against index contents (for all types) ?

  The SAP error message RSD_TREX517 typically indicates an issue with the consistency between the tables and the index contents in the context of SAP BW (Business Warehouse) and its integration with the TREX search engine. This error can arise when there are discrepancies between the data stored in the database tables and the data indexed by TREX, which can lead to problems in data retrieval and reporting.
  Cause:
  
  Data Inconsistency: The most common cause of this error is that the data in the underlying database tables has changed (e.g., due to data loads, updates, or deletions) without the corresponding updates being made to the TREX index.
  Failed Indexing: If the indexing process fails or is interrupted, it can lead to inconsistencies.
  Data Load Issues: Problems during data extraction, transformation, and loading (ETL) processes can also lead to this error.
  Configuration Issues: Incorrect configuration settings for the TREX or BW system can lead to indexing problems.
  
  Solution:
  To resolve the RSD_TREX517 error, you can follow these steps:
  
  
  Check Index Status:
  
  Go to the SAP BW system and check the status of the TREX index. You can do this using transaction codes like RSD1 (InfoProvider) or RSD2 (DataSource).
  Look for any inconsistencies or errors in the index status.
  
  
  
  Rebuild the Index:
  
  If inconsistencies are found, you may need to rebuild the TREX index. This can typically be done through the SAP BW administration tools.
  Use transaction RSCONN01 to check the connection to TREX and ensure it is functioning correctly.
  Use transaction RSD1 to navigate to the InfoProvider and then choose the option to "Rebuild Index".
  
  
  
  Check Data Load Processes:
  
  Review the data load processes to ensure that they are completing successfully without errors. Check the process chains and monitor for any failures.
  If there are issues, resolve them and re-trigger the data load.
  
  
  
  Consistency Check:
  
  Perform a consistency check on the InfoProvider. This can be done using transaction RSD1 and selecting the "Check" option.
  Follow any recommendations provided by the system.
  
  
  
  Update Statistics:
  
  Sometimes, updating the statistics for the database tables can help resolve indexing issues. This can be done through the database administration tools.
  
  
  
  Consult SAP Notes:
  
  Check the SAP Support Portal for any relevant SAP Notes that may address this specific error. There may be patches or updates available that can resolve the issue.
