The document discusses various topics related to ABAP including message debugging, file transfer, debugging modes, and type groups. It provides details on how to create messages in ABAP programs, perform file transfer between the application and operating system, set debugging modes, and work with type groups. It also describes uploading and downloading data between the application server and a PC.

- 19. File Transfer
- 20. File Transfer (Application Server) There are 3 steps for file transfer Open File Read/Write File Close File
- 21. File Transfer * Prepare Internal Table Data all_customers like customers occurs 0 with header line. Data msg_txt(50). Parameters filename(128) default ‘cust omersdata .t xt ’ lower case. Start-of-selection. Select * from customers into table all_customers.
- 22. File Transfer * Opening a file Open dataset filename for output in text mode encoding default message msg_txt. If sy-subrc <> 0. Write: ‘File cannot be opened .Reason :’,msg_txt. else.
- 23. File Transfer * Transferring data to a file Loop at all_customers. Transfer all_customers to filename. Endloop. * Closing a file Close dataset filename. Endif.
- 25. File Transfer (Appending Data) * Opening a file Open dataset filename for appending in text mode encoding default message msg_txt. If sy-subrc <> 0. Write: ‘File cannot be opened .Reason :’,msg_txt. else . ...
- 26. Reading Data from OS File * Reading data from a file Parameters filename(128) default ‘cust omersdata .t xt ’ lower case. Data msg_txt(50). Data all_customers like customers occurs 0 with header line. Start-of-selection. Open dataset filename for input in text mode encoding default message msg_txt. If sy-subrc <> 0. Write: ‘File cannot be opened .Reason :’,msg_txt. else .
- 27. Reading Data from OS File Do. Read dataset filename into all_customers. if sy-subrc <> 0. Exit. endif. Append all_customers. Enddo. Close dataset filename. Endif.
- 28. Deleting OS File Parameters filename(128) default ‘cust omersdata . txt ’ lower case. START-OF-SELECTION. Delete dataset filename. If sy-subrc = 0. write: / ‘Delete OK’. Endif.
- 29. Working with File on Presentation Server
- 30. Download Data to PC * Download data from PC parameters filename like rlgrap-filename default ‘c:\cust omers .txt’. Data all_customers like customers occurs 0 with header line. START-OF-SELECTION. Select * from customers into table all_customres.
- 31. Download Data to PC C ALL FUNCTION ‘DOWNLOAD’ Exporting filename = filename Tables data_tab = all_customers Exceptions file_open_error = 1 … others = 5 .
- 32. Download Data to PC Case sy-subrc. When 1. Write: ‘Error when file opened’. When 2. Write: ‘Error during data transfer’. … When 0. Write: / ‘Data Download Finish’. Endcase.
- 33. Upload Data from PC * Upload data to PC parameters filename like rlgrap-filename default ‘c:\cust omers .txt’. Data all_customers like customers occurs 0 with header line. START-OF-SELECTION.
- 34. Upload Data from PC CALL FUNCTION ‘UPLOAD’ Exporting filename = filename Tables data_tab = all_customers Exceptions file_open_error = 1 … others = 5 .
- 35. Upload Data from PC Case sy-subrc. When 1. Write: ‘Error when file opened’. When 2. Write: ‘Error during data transfer’. … When 0. Insert customers from table all_customers. … Endcase.
- 36. Upload/Download Data in Background Call function ‘WS_ DOWNLOAD’ Exporting filename = filename ... and Call function ‘ WS_UP LOAD’ Exporting filename = filename ...
