  The SAP error message DH151 indicates that there is no index available for the specified search help parameter, which is required for the search help to function properly. This error typically arises when you are trying to use a search help that relies on an index for efficient data retrieval, but the index is either not defined or not available for the field in question.
  Cause:
  
  Missing Index: The most common cause is that the database index for the specified field is not created or is not active.
  Display Field: The field you are trying to use as a search help parameter is only a display field and does not have an associated index.
  Configuration Issues: There may be issues in the configuration of the search help or the underlying database table.
  
  Solution:
  
  
  Create or Activate Index:
  
  Check if an index exists for the field in the database table. If it does not exist, you may need to create one.

  Check Search Help Configuration:
  
  Ensure that the search help is correctly configured to use the appropriate fields and that the fields are indexed as needed.
