  The SAP error message /BOBF/BDEF004 Action &1: Parameter type not supported [BOPF] typically occurs in the context of Business Object Processing Framework (BOPF) when there is an issue with the parameters being passed to an action in a BOPF business object. This error indicates that the parameter type being used is not supported by the action defined in the BOPF definition.
  Cause:
  
  Unsupported Parameter Type: The action you are trying to execute may have parameters that are not of the expected type. For example, if the action is defined to accept a certain data type (like a specific structure or primitive type) and you are passing a different type, this error will occur.

  Data Type Mismatch: There could be a mismatch between the data types defined in the BOPF action and the data types being passed from the calling program or transaction.
  
  Solution:
  
  Check Action Definition: Review the BOPF action definition in the BOPF configuration. Ensure that the parameters defined in the action match the types of the parameters you are passing.
  Parameter Types: Verify that the parameters you are passing to the action are of the correct type. If the action expects a certain structure or data type, ensure that you are providing that exact type.
  Debugging: Use debugging tools to trace the execution and see what parameters are being passed to the action. This can help identify any discrepancies.
  Documentation: Refer to the BOPF documentation for the specific business object and action to understand the expected parameter types and structures.
