• What is the cause and solution for SAP error message PT021 - The parameter OUT_PARAMETERS is mandatory ?

  The SAP error message PT021, which states "The parameter OUT_PARAMETERS is mandatory," typically occurs in the context of using the SAP Process Integration (PI) or Process Orchestration (PO) when dealing with function modules or methods that require specific output parameters to be defined.
  Cause:
  The error indicates that a required output parameter, OUT_PARAMETERS, has not been provided in the function call or method invocation. This can happen due to:
  
  Missing Output Parameter: The function module or method you are trying to call expects an output parameter that has not been defined or passed.
  Incorrect Function Call: The function call may be incorrectly structured, leading to the omission of required parameters.
  Configuration Issues: There may be issues in the configuration of the process or the mapping that leads to the absence of expected parameters.
  
  Solution:
  To resolve the PT021 error, you can take the following steps:
  
  
  Check Function Module/Method Definition: Review the definition of the function module or method you are calling. Ensure that you understand which parameters are required, especially the OUT_PARAMETERS.
  
  
  Provide Required Parameters: Make sure that you are passing all mandatory parameters, including OUT_PARAMETERS, in your function call. If you are using a mapping or transformation, ensure that the output parameters are correctly mapped.
  
  
  Review Mapping Configuration: If this error occurs in a mapping scenario, check the mapping configuration to ensure that all necessary output fields are defined and correctly mapped.
  
  
  Debugging: If you have access to debugging tools, you can set breakpoints and step through the code to see where the parameters are being set and identify why OUT_PARAMETERS is not being populated.
  
  
  Consult Documentation: Refer to the SAP documentation for the specific function module or method to understand the expected parameters and their usage.
  
  
  Check for Updates: Ensure that your SAP system is up to date, as sometimes bugs or issues are resolved in newer versions or patches.
  
  
  Related Information:
  
  SAP Notes: Check SAP Notes related to the specific function module or method for any known issues or additional guidance.
  SAP Community: Engage with the SAP Community forums to see if others have encountered the same issue and what solutions they found.
  Transaction Codes: Familiarize yourself with relevant transaction codes (like SE37 for function modules) to explore the function module's details and parameters.
  
  By following these steps, you should be able to identify the cause of the PT021 error and implement a solution to resolve it.
