I never knew about that restriction and looking at the FCOM, I can’t find such a restriction..
can somebody bring clarification?

thank you

Hi,

in DSC-22_30-80-30-20 there is a note :

Note: if APPR pb is pressed earlier, FINAL APP mode may engage. As a consequence,
resulting speed and altitude management in FINAL APP may be inappropriate before
FDP.

They are basically telling You that it could bust the constraints, hence arm APP when your TO point is the FDP.
