• What is the cause and solution for SAP error message ED160 - You can only use data includes to enhance a TOP include ?

  The SAP error message ED160, which states "You can only use data includes to enhance a TOP include," typically occurs when you are trying to include a data structure or a data type in a way that is not allowed by the SAP ABAP programming model. This error is related to the use of includes in ABAP programs, particularly when dealing with TOP includes and data includes.
  Cause:
  
  
  Incorrect Include Usage: The error arises when you attempt to include a data structure or a data type in a TOP include (the main include of a program) instead of a data include. In ABAP, TOP includes are meant for program-level declarations, while data includes are specifically designed for defining data structures.
  
  
  Program Structure Violation: The ABAP program structure has specific rules regarding where certain types of declarations can be made. If you try to declare a data structure in a TOP include, it will lead to this error.
  
  
  Solution:
  
  
  Use Data Includes: Ensure that any data structures or types you are trying to include are placed in a data include rather than a TOP include. You can create a new data include or use an existing one to define your data structures.
  
  
  Check Include Placement: Review the placement of your includes in the program. Make sure that any data-related includes are correctly placed in the data section of the program.
  
  
  Modify the Program Structure: If you have control over the program, modify the structure to comply with SAP's guidelines. Move any data declarations to the appropriate data includes.
  
  
  Review Documentation: Consult the SAP documentation or ABAP programming guidelines for more information on the correct usage of includes and the structure of ABAP programs.
  
  
  Related Information:
  
  ABAP Program Structure: Understanding the structure of ABAP programs, including the distinction between TOP includes and data includes, is crucial for effective programming.
  Data Types and Structures: Familiarize yourself with how to define and use data types and structures in ABAP, including the use of TYPES, DATA, and INCLUDE statements.
  SAP Notes and Community: Check SAP Notes or the SAP Community for any specific notes related to this error message, as there may be updates or additional guidance available.
  
  By following these steps and understanding the underlying principles of ABAP programming, you should be able to resolve the ED160 error effectively.
