Usually if the screen contains any required or mandatory input field & we run the Module pool program, the screen appears & if we want to come out of the program it will not allow us. We have to give the mandatory field on the screen & then we can come out of the program by clicking on the application tool bar buttons. To overrule this issue, generally we use AT EXIT-COMMAND at PAI of the screen to force come out from the screen that contains a required field without filling any value to it.
Lets take an example that we have two screens 9000 & 9001. In the 9000 screen we have required input field and a single record is displayed on 9001 screen based on the input.
