This question already has an answer here:
We know that there are multiplicity of different works/sources in Harry Potter Universe:
HP books 1-7
Associated JKR books (Beedle the Bard, QTTA, HP Prequel story, Magical Beasts)
HP Movies 1-7
Harry Potter amusement parks
Possibly, other non-JKR franchise works, though to the best of my knowledge none exist as of now and none are planned.
assorted fan fiction :)
Given that the universe is pretty big/complex, with many sources, it's not surprising that there already are discrepancies between different sources (the obvious ones between books and movies; ones between different books; and ones between books and JKR interviews).
Is there an official position of JKR/Harry Potter franchise on HP Universe canon structure?
NOTE: "No canon" and "No current official position" are two different answers.
