• What is the cause and solution for SAP error message ESH_IF_INA026 - 'SupportedService' has to be indicated as filter attribute ?

  The SAP error message ESH_IF_INA026 indicates that a specific attribute, in this case, 'SupportedService', must be defined as a filter attribute in the context of the SAP Enterprise Search (SAP ESH) or SAP Information Access (INA) framework. This error typically arises when there is a mismatch in the configuration of the search model or when the search service is not properly set up to handle the specified attribute.
  Cause:
  
  Configuration Issue: The attribute 'SupportedService' is not marked as a filter attribute in the search model configuration. This means that the system does not recognize it as a valid filter for search queries.
  Model Definition: The search model may not be correctly defined to include all necessary attributes, leading to this error when a search is executed.
  Data Source Issues: The data source from which the search is pulling information may not have the 'SupportedService' attribute properly configured.
  
  Solution:
  
  
  Check Search Model Configuration:
  
  Go to the SAP ESH or INA configuration settings.
  Locate the search model that is being used.
  Ensure that 'SupportedService' is included in the list of filter attributes. If it is not, you will need to add it.
  
  
  
  Modify the Model:

  This typically involves editing the model in the SAP GUI or using the relevant transaction codes (like EHS_MODEL or similar).
  
  
  
  Rebuild Index:
  
  After making changes to the model, it may be necessary to rebuild the search index to ensure that the changes take effect.
  This can usually be done through the administration tools provided in the SAP ESH or INA framework.
