  The SAP error message EMMA381 indicates that a required parameter is missing when calling a method in the ABAP programming environment. This error typically occurs in the context of method calls in ABAP classes, where certain parameters are defined as mandatory but are not provided during the method invocation.
  Cause:
  The error is caused by one of the following:
  
  Missing Parameter: The method being called requires a parameter that has not been supplied.
  Incorrect Method Call: The method is being called with an incorrect signature or with the wrong number of parameters.
  Dynamic Calls: If the method is being called dynamically (e.g., using CALL METHOD), the parameters may not be correctly specified.

    EXPORTING
      param1 = value1
      param2 = value2.  " Ensure all required parameters are included
