• What is the cause and solution for SAP error message RS2HANA_VIEW081 - External SAP HANA view: Variable has no default value ?

  The SAP error message RS2HANA_VIEW081 indicates that an external SAP HANA view has a variable that does not have a default value assigned. This can occur when you are trying to execute a query or report that relies on a HANA view, and one or more of the variables required for the execution are not provided with default values.
  Cause:
  
  Missing Default Value: The variable in the HANA view is defined without a default value, and the query execution requires this variable to be populated.
  Variable Configuration: The variable may be configured to require user input at runtime, but if the system is not set up to provide a default, it leads to this error.
  Data Source Changes: If the underlying data source or the structure of the HANA view has changed, it may affect how variables are handled.
  
  Solution:
  
  
  Assign Default Values:
  
  Go to the HANA view in the SAP HANA Studio or Web IDE.
  Locate the variable that is causing the issue.
  Assign a default value to the variable in the view definition.
  
  
  
  Modify Query Execution:
  
  If the variable is meant to be filled at runtime, ensure that the query or report execution is set up to prompt for the variable value.
  If you are using a report or query tool, check if you can set default values for the variables in the report settings.
  
  
  
  Check Variable Properties:
  
  Review the properties of the variable in the HANA view to ensure it is configured correctly.
  Ensure that the variable is not set to mandatory if it should have a default value.
  
  
  
  Testing:
  
  After making changes, test the HANA view or the report to ensure that the error is resolved and that the query executes successfully.
