  11. Debugging

  12. Debugging Mode

  13. Debugging Mode : Internal Table

  14. Debugging Mode : Internal Table

  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 ‘customersdata.txt’ 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.

  24. Transaction : AL11

  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 ‘customersdata.txt’ 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 ‘customersdata.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:\customers.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 CALLFUNCTION ‘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:\customers.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_UPLOAD’ Exporting filename = filename ...

  37. Type Group: SE11
