• What is the cause and solution for SAP error message RSRTS_CDS127 - Parameter &1: Default cannot be determined (depends on user input) ?

  The SAP error message RSRTS_CDS127, which states "Parameter &1: Default cannot be determined (depends on user input)," typically occurs in the context of SAP BW (Business Warehouse) or SAP HANA when working with queries or data sources that involve variables or parameters that require user input.
  Cause:
  This error generally arises when:
  
  Missing Default Values: The parameter in question does not have a default value set, and the system cannot determine what value to use without user input.
  Variable Configuration: The variable might be configured in such a way that it requires user input at runtime, but the query is being executed in a context where that input is not provided.
  Query Execution Context: The query is being executed in a context (like a background job or a report) where user interaction is not possible, leading to the inability to provide the necessary input.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Set Default Values:
  
  Go to the variable settings in the query designer or the relevant data source.
  Ensure that default values are set for the parameters that are causing the issue. This can often be done by editing the variable properties and specifying a default value.
  
  
  
  Check Variable Properties:
  
  Review the properties of the variable to see if it is set to require user input. If it is, consider whether it can be changed to have a default value or if it can be made optional.
  
  
  
  Modify Query Execution Context:
  
  If the query is being executed in a non-interactive context (like a background job), ensure that all required parameters have default values or are set to optional.
  
  
  
  Testing:
  
  After making changes, test the query execution to ensure that the error no longer occurs.
  
  
  
  Documentation and Help:
  
  Refer to SAP documentation or help resources for more detailed guidance on variable handling and query design in SAP BW or HANA.
