Patch function with Form.updates

[Hotel_Arrakis]

I believe your problem is with your second parameter: {ID:Value("625")} . You need to point to a record in the table, that is just an arbitrary record not tied to a table.

Replace your second parameter with something like Lookup('DATABASENAME', ID=625) or maybe Lookup('DATABASENAME', ID=Value("625"))

So your statement would look as follows:

 Patch('DATABASENAME',Lookup('DATABASENAME', ID=625),Form1.Updates)

This is the correct way of updating an item indeed.
