• What is the cause and solution for SAP error message ESH_SEARCH174 - Duplicate key template &1, node &2, attribute &3 ?

  The SAP error message ESH_SEARCH174 indicates that there is a duplicate key issue in the context of the Enterprise Search (ESH) framework. This error typically arises when there are multiple entries in the search index that have the same key for a specific template, node, and attribute combination. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  Duplicate Entries: The most common cause of this error is that the data being indexed contains duplicate entries for the specified key template, node, and attribute. This can happen due to data inconsistencies or issues in the data extraction process.
  Configuration Issues: There may be misconfigurations in the search model or the way the data is being indexed, leading to duplicates being created.
  Data Source Problems: If the data source itself has duplicates, these will propagate into the search index.
  
  Solution:
  
  
  Identify Duplicates: 
  
  Check the data source for duplicates. You can run queries against the database or use tools to identify duplicate records based on the key template, node, and attribute.
  Use transaction codes like SE16 or SE11 to inspect the relevant tables.
  
  
  
  Data Cleansing: 
  
  If duplicates are found in the data source, clean the data to ensure that each key is unique. This may involve merging records or removing unnecessary duplicates.
  
  
  
  Adjust Indexing Configuration: 
  
  Review the configuration of the search model and indexing settings in the ESH. Ensure that the settings are correctly defined to prevent duplicates from being indexed.
  Check the settings in the ESH configuration (transaction EHS_CONFIG) to ensure that the key attributes are correctly defined.
  
  
  
  Re-indexing: 
  
  After resolving the duplicates in the data source, you may need to re-index the search data. This can be done through the ESH administration tools or relevant transactions.
  Use transaction EHS_REINDEX to trigger a re-indexing process.
  
  
  
  Monitoring and Logging: 
  
  Enable logging for the indexing process to capture any future occurrences of this error. This can help in diagnosing issues more effectively.
