Create Transaction for local class method In this demo I am going to show how to create transaction on a local class method. Step1: First create a local class in a report from transaction SE38. REPORT z_demo_oop_jg . *---------------------------------------------------------------------* * CLASS create_report DEFINITION *---------------------------------------------------------------------* * *---------------------------------------------------------------------* CLASS create_report DEFINITION. PUBLIC SECTION. METHODS: main. PRIVATE SECTION. DATA: i_data TYPE STANDARD TABLE OF sbook INITIAL SIZE 0. METHODS: fetch_data, display_data. ENDCLASS. "create_report DEFINITION *---------------------------------------------------------------------* * CLASS create_report IMPLEMENTATION *---------------------------------------------------------------------* * *---------------------------------------------------------------------* CLASS create_report IMPLEMENTATION. METHOD fetch_data. * Select 100 records from SBOOK table SELECT * FROM sbook INTO TABLE i_data UP TO 100 ROWS. ENDMETHOD. "fetch_data METHOD display_data. CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY' EXPORTING i_structure_name = 'SBOOK' TABLES t_outtab = i_data EXCEPTIONS program_error = 1 OTHERS = 2. IF sy-subrc 0. MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4. ENDIF. ENDMETHOD. "display_data METHOD main. fetch_data( ). display_data( ). ENDMETHOD. "main ENDCLASS. "create_report IMPLEMENTATION
Step2. Now from transaction SE93 create a transaction for the method MAIN as shown in the screen shots given below: Give a transaction name and press create button. In the next screen give a description and choose the proper radio button In the next screen provide report name (where the local class is defined), local class name and method name.
