How to updating Physical Inventory in Sage 300

I'm a new user of Sage 300 I wanna Update my physical inventory because he's different with what I have on hand, so when is connect to the POS (Orion POS) I'm using the data are different to what I have on hand sometimes I can't even sell some Items. And the thing is when I look in the Inventory Movement everything is correct, I wanna know if it's possible to match The Physical Inventory to the Inventory Movement? Just Updating it
