• What is the cause and solution for SAP error message ESH_HANA_ADMIN201 - Keys have to be defined in model (node &1 is not table-based) ?

  The SAP error message ESH_HANA_ADMIN201 indicates that there is an issue with the configuration of a model in the SAP HANA environment, specifically related to the definition of keys for a model that is not table-based. This error typically arises in the context of SAP HANA Search or SAP HANA modeling when the system expects certain keys to be defined for a model that is not based on a traditional database table.
  Cause:
  
  Model Type: The model you are working with is not a table-based model (e.g., it could be a view or a calculation view), and as such, it does not have the same key definition requirements as a table-based model.
  Missing Key Definitions: The model may require specific key fields to be defined for it to function correctly, but these keys have not been specified.
  Incorrect Configuration: The model may be incorrectly configured, leading to the system not recognizing the necessary keys.
  
  Solution:
  
  
  Define Keys: Ensure that the model has the necessary key fields defined. You can do this by:
  
  Opening the model in the SAP HANA Studio or Web IDE.
  Navigating to the properties of the model and checking the key definitions.
  Adding the required key fields if they are missing.
  
  
  
  Check Model Type: If the model is not intended to be table-based, consider whether it should be converted to a table-based model or if the key definitions can be adjusted to fit the current model type.
  
  
  Review Documentation: Consult the SAP documentation for the specific type of model you are working with to understand the key requirements and how to properly configure them.
  
  
  Testing: After making changes, test the model to ensure that it functions as expected and that the error message no longer appears.
