When the user selects a function in a transaction, the system duplicates the function code into a specifically designated work field called OK_CODE. This field is Global in ABAP/4 Module Pool. The OK _CODE can then be calculated in the corresponding PAI module. The function code is always passed in exactly the same way, regardless of whether it comes from a screen’s pushbutton, a menu option, function key or other GUI element.
