• What is the cause and solution for SAP error message ESH_CHECK_CONN023 - Response attr. of connector &1 do not match response attr. in buffer ?

  The SAP error message ESH_CHECK_CONN023 indicates that there is a mismatch between the response attributes of a connector and the response attributes stored in the buffer. This error typically occurs in the context of SAP Enterprise Search or when working with connectors that retrieve data from various sources.
  Cause:
  The error can be caused by several factors, including:
  
  
  Schema Changes: If there have been changes to the data structure or schema of the source system that the connector is trying to access, the attributes expected by the connector may no longer match those in the buffer.
  
  
  Configuration Issues: Incorrect configuration of the connector or the search system can lead to mismatches in expected attributes.
  
  
  Data Consistency Issues: If the data in the source system has been modified or is inconsistent, it may not match the expected attributes.
  
  
  Buffer Corruption: The buffer that stores the response attributes may be corrupted or not updated correctly.
  
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check Connector Configuration: Review the configuration of the connector to ensure that it is set up correctly and that the expected attributes are defined properly.
  
  
  Update Buffer: Clear or refresh the buffer to ensure that it is in sync with the current state of the source system. This may involve re-indexing or reloading data.
  
  
  Review Schema Changes: If there have been recent changes to the data schema in the source system, update the connector configuration to reflect these changes.
  
  
  Check Logs: Look at the logs for more detailed error messages that may provide additional context about the mismatch.
  
  
  Test Connection: Use the connection test feature in the SAP system to verify that the connector can successfully connect to the source system and retrieve the expected attributes.
  
  
  Consult Documentation: Refer to SAP documentation or support resources for specific guidance related to the connector you are using.
