The example shows how to call modules on a condition-related basis.

ABAP_SOURCE_CODE
ABAP_EXEC

ABAP_DESCRIPTION
The static next screen number of screen 100 is 100. The input fields have been assigned the screen fields input1 , input2 , and input3 . The function code of the pubshbutton is EXECUTE . In GUI status STATUS_100 , the icon Cancel (F12) has been activated using the function code CANCEL with the function type E . Also, the F2 function key has been assigned the CS function code with the function type S , and the F8
function key has been assigned the EXECUTE function code without any specific function type. The screen flow logic is as follows:
PROCESS BEFORE OUTPUT.
MODULE init_screen_100.
PROCESS AFTER INPUT.
MODULE cancel AT EXIT-COMMAND.
CHAIN.
FIELD: input1, input2.
MODULE module_1 ON CHAIN-INPUT.
FIELD input3 MODULE module_* ON *-INPUT.
MODULE module_2 ON CHAIN-REQUEST.
ENDCHAIN.
FIELD input1 MODULE c1 AT CURSOR-SELECTION.
CHAIN.
FIELD: input2, input3.
MODULE c2 AT CURSOR-SELECTION.
ENDCHAIN.
MODULE cursor AT CURSOR-SELECTION.
Issuing information messages, the program shows which modules are called after which user actions and which data is transported:

If one of the input fields 1 or 2 is not initial, each user action calls module module_1

If one of the three input fields has been modified, each user action calls module module_2 .

If a * entry has been made in input field 3, each user action calls module module_* .

If the F2 function is chosen or if a text field of the screen is double-clicked, module cursor is called.

If the F2 function is chosen or if the input field 1 is double-clicked, module c1 is called.

If the F2 function is chosen or if input field 2 or 3 is double-clicked, module cursor is called. Module c2 is never called since the statement MODULE ... AT CURSOR SELECTION occurs twice and only the last one is processed.
