Append Not Working

I have table A with an autonumber field called A_ID. I'm trying to append these records into table B which as one autonumber field called B_ID and also the field A_ID. Table is new and empty.  When I try to append A_ID from table A to table B it appends 0 rows because of validation rule violations. What does this refer to?  The only field I'm appending is A_ID into table B. Also field A_ID is a Long Integer in both tables.

Well, are there any Validation rules on the A_ID in the 2nd table?
Or any other Required fields?

Field A_ID in Table B, (the table I'm trying to append to), has No under Required and Yes (Duplicates Ok). That's it.

Are there any other fields in that table besides B_ID (the Autonumber) ?

B_ID is the primary key in Table B and it is an autonumber field.  Table B is empty.  I didn't not include or reference B_ID in the append query.

Ah!  Yes, some of the other fields are required.
