• What is the cause and solution for SAP error message RSRTS_CDS128 - Filter &1: Default cannot be determined (depends on user input) ?

  The SAP error message RSRTS_CDS128 typically occurs in the context of SAP BW (Business Warehouse) when working with Composite Data Sources (CDS) or when executing queries in the SAP BW Query Designer. The error message indicates that the system is unable to determine a default value for a filter based on user input.
  Cause:
  
  Missing Default Values: The filter in question may not have a default value set in the query definition or the underlying data model.
  User Input Dependency: The filter might depend on user input, and if the user does not provide a valid input, the system cannot determine a default.
  Data Model Issues: There may be issues with the underlying data model or the way the data source is defined, leading to ambiguity in determining default values.
  Authorization Issues: Sometimes, the user may not have the necessary authorizations to access certain data, which can lead to the inability to determine defaults.
  
  Solution:
  
  Check Query Definition: Review the query definition in the Query Designer to ensure that all filters have appropriate default values set. If a filter is mandatory, ensure that it has a default value.
  User Input: Ensure that the user is providing valid input for the filter. If the filter is optional, consider setting a default value that makes sense for the majority of users.
  Data Source Configuration: Verify the configuration of the underlying data source (e.g., InfoProvider, CDS view) to ensure that it is correctly set up and that all necessary fields are available.
  Authorization Check: Ensure that the user has the necessary authorizations to access the data related to the filter. This can be checked in the user roles and authorizations.
  Testing: Test the query with different user inputs to see if the error persists. This can help identify if the issue is related to specific input values.
  Consult Documentation: Refer to SAP documentation or notes related to the specific version of SAP BW you are using, as there may be known issues or patches available.
