• What is the cause and solution for SAP error message RSRTS_CDS064 - Derivation of parameter &1 uses unknown parameter &2 ?

  The SAP error message RSRTS_CDS064 indicates that there is an issue with the derivation of a parameter in a CDS (Core Data Services) view or a query. Specifically, it states that the derivation of parameter &1 is attempting to use an unknown parameter &2. This typically occurs in the context of reporting or data extraction when the system cannot resolve a parameter that is referenced in the logic of the CDS view or query.
  Cause
  The error can be caused by several factors:
  
  Missing Parameter Definition: The parameter &2 that is being referenced in the derivation of parameter &1 is not defined in the CDS view or query.
  Typographical Error: There may be a typo in the parameter name, leading to the system not recognizing it.
  Changes in Data Model: If there have been recent changes to the underlying data model or the CDS view, it may have affected the parameters.
  Transport Issues: If the CDS view or query was transported from one system to another, it may not have included all necessary definitions.
  
  Solution
  To resolve the error, you can take the following steps:
  
  
  Check Parameter Definitions: Verify that the parameter &2 is correctly defined in the CDS view or query. Ensure that it is spelled correctly and that it is included in the parameter list.
  
  
  Review the Logic: Look at the derivation logic for parameter &1 to ensure that it is correctly referencing existing parameters. If &2 is supposed to be a parameter, make sure it is included in the definition.
  
  
  Check for Changes: If there have been recent changes to the CDS view or the underlying data model, review those changes to ensure that they did not inadvertently remove or alter the parameter.
  
  
  Transport Check: If the issue arose after a transport, check the transport logs to ensure that all necessary objects were included in the transport request.
  
  
  Debugging: If you have access to the ABAP development environment, you can debug the CDS view or query to see how parameters are being resolved at runtime.
  
  
  Consult Documentation: Review the SAP documentation or notes related to the specific CDS view or query for any known issues or updates.
