There are three tables – table specific to item, table specific to distributor and a join table that has existing combination of item and distributor. Usually use fill in the jon table to with the possible (existing combination of item and the distributor level where they are sold. I need a union query oof some sort that returns a Cartesian product of the two tables – items Distributor join table and distributor List table  - so that for example –
If item T23 was listed with only distributor D01 in the join table >> then the query returns a total of 5 rows – with the possible combination of that item and all the other distributor list but puts 0 for the price. See attached image and DB.
Thank you

You don't need a Union.  A union query stacks lists on top of each other so all rows from tblA are returned followed by all rows from tblB.  Both tblA and tblB MUST have the same format.  A join compares two tables and returns matches (inner join), rows from tblA without rows in tblB (left join), rows from tblB without rows in tblA (right join), all rows from tblA matched to every row in tblB (cross join or Cartesian product).

So to create a Cartesian Product, add the two tables to the QBE.  Select the columns you want from each table.  Do NOT draw a join line.

A and B have different formats because they are different tables

I said you don't need a union so you don't need to worry about column format or order.  You need a query that creates a Cartesian Product.  Add both tables to the QBE.  Do NOT draw a join line.  Select the columns you want from either table.
