• What is the cause and solution for SAP error message RSDD_CS008 - This calculation view type requires exactly &1 inputs, but has &2 ?

  The SAP error message RSDD_CS008 indicates that there is a mismatch between the expected number of input parameters for a calculation view and the actual number of inputs provided. Specifically, the message states that a calculation view requires a certain number of inputs (denoted as &1), but it has received a different number of inputs (denoted as &2).
  Cause:
  
  Incorrect Configuration: The calculation view may be configured to require a specific number of input parameters, but the actual implementation or the way it is being called does not match this requirement.
  Changes in the View: If the calculation view was modified (e.g., inputs were added or removed) but the dependent objects or queries were not updated accordingly, this error can occur.
  Data Source Issues: If the calculation view is being used as a data source in another object (like a report or another view), and the calling object does not provide the correct number of inputs, this error will be triggered.
  
  Solution:
  
  Check Calculation View Definition: Open the calculation view in the SAP HANA Studio or the relevant modeling tool and verify the number of input parameters defined. Ensure that it matches the expected number of inputs.
  Update Dependent Objects: If the calculation view has been modified, ensure that all dependent objects (like queries, reports, or other views) are updated to provide the correct number of inputs.
  Test the View: Execute the calculation view directly in the modeling tool to see if it runs without errors. This can help isolate whether the issue is with the view itself or with how it is being called.
  Check for Documentation: Review any documentation or comments associated with the calculation view to understand its intended use and input requirements.
  Consult SAP Notes: Check the SAP Support Portal for any relevant notes or updates related to this error message, as there may be specific patches or updates that address known issues.
  
  Related Information:
  
  Calculation Views: These are used in SAP HANA to perform complex calculations and aggregations on data. They can have input parameters that allow for dynamic filtering and calculations.
  Input Parameters: These are variables that can be passed to the calculation view at runtime, allowing for flexible data retrieval based on user input or other criteria.
  SAP HANA Studio: This is the primary tool used for modeling and managing SAP HANA database objects, including calculation views.
  
  By following these steps, you should be able to identify and resolve the issue causing the RSDD_CS008 error message.
