I can't think of any circumstances where you would need to do what you are trying to do unless there is a flaw in the design of the database.

If you set the ID for each of the tables to Autonumber, it will always start at 1 (unless you format it to start at a different numer) and you will get ID numbers duplicated in each table but as you will give each of the ID fields a different name in each table, the database will not see them as duplications. I would put all the bars, restaurants etc in the same table and create a category field in which you identify each record as either a bar, restaurant etc then they will all have different ID numbers in the same table. It will be easier to handle and extract data The “No duplication” control only applies to that table, not the whole database of several tables.
