• What is the cause and solution for SAP error message APS_CKE_PARSER056 - Parameter &1 of CDS view &2 is not mapped. ?

  The SAP error message APS_CKE_PARSER056 indicates that there is an issue with a Core Data Services (CDS) view where a parameter is not properly mapped. This typically occurs when the CDS view is expecting a parameter to be passed, but it is either missing or incorrectly defined.
  Cause:
  
  Missing Parameter Mapping: The parameter defined in the CDS view is not being passed correctly from the calling program or another CDS view.
  Incorrect Parameter Name: The name of the parameter in the calling context does not match the name defined in the CDS view.
  Data Type Mismatch: The data type of the parameter being passed does not match the expected data type in the CDS view.
  Changes in CDS View: If the CDS view has been modified (e.g., parameters added or removed) and the calling program has not been updated accordingly, this error can occur.
  
  Solution:
  
  Check Parameter Definition: Review the CDS view definition to ensure that all parameters are correctly defined and that their names and data types are as expected.
  Update Calling Program: Ensure that the program or view calling the CDS view is passing the required parameters correctly. This includes checking for typos in parameter names and ensuring that the correct data types are being used.
  Test with Sample Values: If possible, test the CDS view with sample values to see if the error persists. This can help isolate whether the issue is with the parameter mapping or with the data being passed.
  Review Changes: If the CDS view has been recently modified, review the changes to ensure that all dependent objects (like reports, other views, etc.) have been updated accordingly.
  Debugging: Use debugging tools to trace the execution and see where the parameter mapping fails. This can provide insights into what is being passed and where the mismatch occurs.
