• What is the cause and solution for SAP error message ESH_CA_CACHE034 - Algorithm &1 does not support unlimited entries ?

  The SAP error message ESH_CA_CACHE034 indicates that the algorithm specified does not support unlimited entries in the context of the SAP Enterprise Search (ESH) cache. This error typically arises when the configuration for the search cache is set to allow unlimited entries, but the algorithm being used does not support this setting.
  Cause:
  
  Algorithm Limitation: The algorithm you are using for the cache may have a predefined limit on the number of entries it can handle. When the configuration is set to allow unlimited entries, it conflicts with the algorithm's capabilities.
  Configuration Mismatch: There may be a mismatch between the cache configuration settings and the capabilities of the selected algorithm.
  
  Solution:
  
  
  Change Cache Configuration:
  
  Go to the configuration settings for the search cache in the SAP system.
  Adjust the settings to limit the number of entries to a value that is supported by the algorithm you are using. This may involve setting a specific maximum number of entries instead of allowing unlimited entries.
  
  
  
  Select a Different Algorithm:
  
  If you require unlimited entries, consider switching to a different algorithm that supports this feature. Review the documentation for the available algorithms to find one that meets your requirements.
  
  
  
  Review Documentation:
  
  Check the SAP Help Portal or relevant documentation for the specific algorithms and their limitations. This will help you understand which algorithms can handle unlimited entries and which cannot.
  
  
  
  Consult SAP Notes:
  
  Look for any relevant SAP Notes that might address this specific error or provide guidance on configuration best practices.
  
  
  
  Testing:
  
  After making changes, test the configuration to ensure that the error is resolved and that the search functionality works as expected.
