Check Boxes and Push Buttons

Module pool program has different modules which contains different logic for different screen. Module pool program can be called dialog programming. Any number of screens can be developed by module pool programming. Every screen has a logic which runs at the back end. Module pool program can be executed by Transaction Code only.

Here we have created a program which contains two screens. Initial screen contains an input field and some check boxes. In the input field we are getting the Customer number manually. We have three check boxes. The box which is clicked will be shown on the second screen. That means if we check Name and Country boxes then on the second screen we shall see only the customer name and country code with the customer number. Two push buttons are there and these two buttons have separate functionality for the data processing. Push button DISPLAY only displays the entered customer details and CANCEL will clear the initial screen.

Below is the logic which is written according to the Includes.

We have created two screens here as follows:

PROCESS BEFORE OUTPUT.
 MODULE STATUS_9001.

PROCESS AFTER INPUT.
 MODULE USER_COMMAND_9001.

and

PROCESS BEFORE OUTPUT.
 MODULE STATUS_9002.

PROCESS AFTER INPUT.
 MODULE USER_COMMAND_9002.


We have created a Transaction Code here and below is the output of first screen:



Then we have the first screen as follows:



Now we are entering the input value and check the boxes as per requirement:



Finally we click on the display button and then following output has come:



Now by clicking BACK button on the standard toolbar we come back to the first screen and then again by clicking BACK button we shall go to the home screen:

Hi,
There should not be any problem for 1st screen. If you face problem then please check OK_CODE. You have to enter the OK_CODE on the Element List tab of the screen painter.
