What is the difference between the “change on-input” and “Change on request” in the PAI of a screen?
· ON INPUT The ABAP/4 module is called only if the field contains a value other than its initial value. This initial value is determined by the field’s data type: blanks for character fields, zeroes for numerics. · ON REQUEST The ABAP/4 module is called only if the user has entered a value in the field value since the last screen display. The value counts as changed even if the user simply types in the value that was already there.
