Description

The static next dynpro number of dynpro 100 is 100. The input fields are taken from the program fields carrier and connection. 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.
PROCESS AFTER INPUT.
  MODULE cancel AT EXIT-COMMAND.
PROCESS ON VALUE-REQUEST.
  FIELD carrier MODULE value_carrier.
  FIELD connection MODULE value_connection.

When selecting the F4 help for the individual fields, the user is shown the following types of input help:

• For the airline, the module value_carrier is called at POV. There, the function module F4IF_FIELD_VALUE_REQUEST displays the input help of the component CARRIER1 of the structure DEMOF4HELP from the ABAP Dictionary, namely the search help DEMOF4DE. The selection of the user is passed to the dynpro field carrier.

• For the connection, the module value_connection is called at POV. There, the function module DYNP_VALUES_READ passes the value of the dynpro field carrier to the program. SELECT then extracts the matching values from the database table SPFLI into the internal table values_tab and passes them to the function module F4IF_INT_TABLE_VALUE_REQUEST. The function module displays these values as an input help and passes the selection of the user to the dynpro field connection.
