• What is the cause and solution for SAP error message HV021 - No parameter was passed ?

  The SAP error message HV021 ("No parameter was passed") typically occurs when a function module or a report is called without the necessary parameters being provided. This can happen in various scenarios, such as when using function modules, BAPIs, or when executing certain transactions that require input parameters.
  Causes:
  
  Missing Parameters: The most common cause is that the required input parameters for a function module or report are not being passed correctly.

  Check Function Module/Report Documentation: Review the documentation for the function module or report to ensure you are passing all required parameters.
  Debugging: Use the ABAP debugger to step through the code and identify where the parameters are supposed to be passed and where they are missing.

  Review Custom Code: If the error arises from custom code, review the logic to ensure that parameters are being set and passed correctly.
