This document discusses various topics in ABAP Chapter 6 including messages, debugging, file transfer, and type groups. It provides information on different message types (A, E, W, I, S) and how to use the MESSAGE statement. Debugging modes like internal table and watchpoint are mentioned. The steps for file transfer on the application server including opening, reading/writing, and closing files are outlined. Finally, it briefly discusses the type group transaction SE11.

11. Debugging

12. Debugging Mode

13. Debugging Mode : Internal Table

14. Debugging Mode : Internal Table

15. Debugging Mode : Watchpoint

16. Watchpoint : SAP ECC 6.0

17. How to Set Debugging Mode
 If you want to test
transaction,enter /h in the
command field,press ENTER and
execute the transaction
 Set breakpoints in the program
Utilities->Breakpoints->Set
 Uses BREAK-POINT statement

19. File Transfer

20. File Transfer (Application Server)
x There are 3 steps for file transfer
 Open File
 Read/Write File
 Close File

21. File Transfer
Internal Table

22. File Transfer
Opening a file
pen dataset filename for output in text mode
encoding default message msg_txt.
sy-subrc <> 0.
Write: ‘File cannot be opened .Reason :’,msg_

23. File Transfer
* Transferring data to a file
Loop at all_customers.
Transfer all_customers to filename.
Endloop.
* Closing a file
