• What is the cause and solution for SAP error message ESH_HANA_ADMIN200 - Keys have to be defined either in model or in table/view definition ?

  The SAP error message ESH_HANA_ADMIN200 indicates that there is an issue with the definition of keys in your SAP HANA model or the underlying table/view. This error typically arises when the system expects a key to be defined for a certain model or table/view, but it is either missing or not properly configured.
  Cause:
  
  Missing Key Definition: The model or the table/view does not have a primary key or a unique key defined. In SAP HANA, keys are essential for identifying records uniquely.
  Incorrect Model Configuration: The model may not be correctly set up to reference the keys from the underlying table/view.
  Changes in Table Structure: If the underlying table or view structure has changed (e.g., columns added or removed), the model may not reflect these changes, leading to key definition issues.
  Data Source Issues: If the data source is not properly configured or if there are connectivity issues, it may lead to this error.
  
  Solution:
  
  
  Define Keys in the Model:
  
  Open the model in the SAP HANA Studio or the relevant modeling tool.
  Ensure that a primary key or unique key is defined for the model. This can usually be done in the model properties or settings.
  
  
  
  Check Table/View Definition:
  
  Go to the underlying table or view in the SAP HANA database.
  Verify that the table/view has a primary key or unique key defined. If not, you may need to alter the table/view to add a key.
  
  
  
  Update Model Configuration:
  
  If there have been changes to the underlying table/view, refresh or update the model to ensure it reflects the current structure.
  Revalidate the model to check for any inconsistencies.
  
  
  
  Review Data Source Configuration:
  
  Ensure that the data source is correctly configured and that there are no connectivity issues.
  Check for any errors in the data source that might affect the model.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for specific guidance on defining keys in your version of SAP HANA.
