Its dropdown attribute is L, the output length is 15, the value list attribute is empty, and it is assigned the function code CARRIER . The function code of the pushbutton is CANCEL with the function type E. The dynpro flow logic is as follows: PROCESS BEFORE OUTPUT. PROCESS AFTER INPUT. MODULE cancel AT EXIT-COMMAND. MODULE user_command_100. The static next dynpro number of dynpro 200 is 100. The input field is assigned the component CONNID of the structure DEMOF4HELP from the ABAP Dictionary. Its dropdown attribute is L, the output length is 30, the value list attribute is A, and it is assigned the SELECTED function code. The function code of the pushbutton is CANCEL with the function type E. The dynpro flow logic is as follows: PROCESS BEFORE OUTPUT. MODULE init_listbox. PROCESS AFTER INPUT. MODULE cancel AT EXIT-COMMAND. MODULE user_command_200. The user is not allowed to enter values in the screen fields. When selecting the input field on dynpro 100, the user sees a value list in the list box derived from the input help of the DEMOF4HELP-CARRIER2 field. In this case, this is the search help H_SCARR assigned to the SCARR check table in the ABAP Dictionary. The value list contains the names of the airlines. When the user selects an entry, the dynpro field is filled with the ID of the airline, and the event PAI is raised. The module user_command_100 checks the OK field and calls dynpro 200. At the PBO event of dynpro 200, an internal table called list is filled with values from the database table SPFLI. The key component is filled with the flight connection numbers, and other relevant information is stored in the text field. The list table is passed to the VRM_SET_VALUES function module. When the user selects the input field on dynpro 200, the text column of the internal table is displayed in the list box. When the user selects an entry, the dynpro field is filled with the associated entry from the key column, and the event PAI is raised. The module user_command_200 checks and processes the OK field.
