• What is the cause and solution for SAP error message FUNC_ADT013 - &1 parameters must not be defined after &2 parameters ?

  The SAP error message FUNC_ADT013 typically indicates an issue with the definition of parameters in a function module or method. The message states that certain parameters must not be defined after others, which usually pertains to the order of input and output parameters in the function signature.
  Cause:
  The error occurs when the parameters in a function module or method are not defined in the correct order. In SAP ABAP, the order of parameters is significant, especially when dealing with input (IMPORTING) and output (EXPORTING) parameters. The error message suggests that you have defined parameters in a way that violates the expected sequence.
  For example, if you have defined an EXPORTING parameter after an IMPORTING parameter, this will trigger the error. The correct order should be:
  
  IMPORTING parameters
  EXPORTING parameters
  CHANGING parameters
  TABLES parameters
  
  Solution:
  To resolve the FUNC_ADT013 error, you should:
  
  Check the Function Module/Method Definition: Review the parameter definitions in the function module or method where the error is occurring.
  Reorder Parameters: Ensure that the parameters are defined in the correct order as per the guidelines mentioned above.
  Save and Activate: After making the necessary changes, save and activate the function module or method.
  
  Related Information:
  
  
  Parameter Types: Understand the different types of parameters in ABAP:
  
  IMPORTING: Input parameters that are passed to the function.
  EXPORTING: Output parameters that are returned from the function.
  CHANGING: Parameters that can be both input and output.
  TABLES: Used for passing internal tables.
  
  
  
  Documentation: Refer to the SAP documentation for guidelines on defining function modules and methods, which will provide more context on parameter handling.
  
  
  Testing: After correcting the parameter order, test the function module or method to ensure that it behaves as expected without triggering the error.
  
  
  By following these steps, you should be able to resolve the FUNC_ADT013 error and ensure that your function module or method is correctly defined.
