APS is always doing the same. By manually pressing it the user is able to check the outcome (like linewidth) before the scan starts and with that not performing the scan in case of a very bad shim. Linewidth and water suppression levels are stored in the dicom header and can also be checked retrospectively.
AWS is just optimising water suppression level. The level is always “measured” and displayed (if AWS in on or off).
