• What is the cause and solution for SAP error message FUNC_ADT028 - Parameter comment blocks are not allowed ?

  The SAP error message FUNC_ADT028: Parameter comment blocks are not allowed typically occurs in the context of ABAP development, particularly when using the ABAP Development Tools (ADT) in Eclipse or similar environments. This error indicates that there is an issue with the way comments are formatted in the parameter section of a function module or method.
  Cause:
  The error is caused by the presence of comment blocks (multi-line comments) in the parameter definition of a function module or method. In ABAP, comments should be placed outside of the parameter definitions, as the syntax does not allow for comments to be included directly within the parameter list.
  Solution:
  To resolve this error, you should:
  
  
  Remove Comment Blocks: Ensure that any comments related to parameters are placed outside the parameter definition. Instead of using multi-line comments (e.g., /* comment */), use single-line comments (" comment) before the parameter definitions.
  
  
  Reformat the Code: If you have comments that need to explain the parameters, place them above the parameter section. For example:
  " This parameter is used for input
  " It should contain the user ID
  IMPORTING
    VALUE(user_id) TYPE string
  
  
  Check for Other Syntax Issues: Ensure that there are no other syntax errors in your function module or method that could be causing the issue.
  
  
  Related Information:
  
  ABAP Syntax Rules: Familiarize yourself with the syntax rules for ABAP, especially regarding comments and parameter definitions.
  ABAP Development Tools (ADT): If you are using ADT in Eclipse, ensure that you are using the latest version, as updates may include improvements and bug fixes related to syntax checking.
  SAP Notes and Documentation: Check SAP Notes or the official SAP documentation for any specific guidelines or updates related to this error message.
  
  By following these steps, you should be able to resolve the FUNC_ADT028 error and successfully define your function module or method parameters without issues.
