  • Step 5
    1. Add a START-OF-SELECTION event to your report

    2. Create an instance of the local class lcl_main.

    3. Call the run method.
      That is, enter the following code:

          lcl_main=>create( )->run( ).
      Image depicting step5-create-run-statement

    Class methods are called using => ; instance methods are called using ->.

  • Step 6

    Save and activate your program by choosing Save and Activate in the toolbar.

  • Step 7

    Choose F8 to run your program. An embedded SAP GUI will open inside an Eclipse editor. After checking the output of the report choose Close.

  • Step 8

    You will now enhance the program to output your user name and today’s date. Change the WRITE statement to:

    WRITE: 'Welcome, ', sy-uname, / 'Today is the', sy-datum.

    Image depicting step8-enhance-write

    sy- is the table containing all the system fields. For the complete list, see the ABAP keyword documentation: ABAP System Fields.

    / is simply the new line character. (See also ABAP keyword documentation: WRITE.)

  • Step 9

    Again, choose F8 to run your program. Your output should now look something like this:

    Image depicting step9-run-program-2
  • Step 10

    Your code should look like this:

    *& Report zjp_basic_app
    REPORT z_invoice_items_euro.
    class lcl_main definition create private.
      public section.
        methods run.
        CLASS-METHODS create
            value(r_result) TYPE REF TO lcl_main.
      protected section.
      private section.
    class lcl_main implementation.
      method create.
        create object r_result.
      method run.
        WRITE: 'Welcome, ', sy-uname, / 'Today is the', sy-datum.
        lcl_main=>create( )->run( ).
  • Step 11
