  The SAP error message /OSP/A_MSG057 indicates that mandatory parameters for a Remote Function Call (RFC) are missing. This error typically occurs when an RFC-enabled function module is called without providing all the required input parameters.
  Cause:
  The error is caused by one or more of the following reasons:
  
  Missing Parameters: The RFC call is missing one or more mandatory parameters that are required by the function module.
  Incorrect Function Module Call: The function module being called may not be correctly specified, or the parameters being passed do not match the expected signature.
