Get only the rows where there are no matches in the tables

Question

To include in the results of a join with no matching rows, you can use a full outer join. In MS SQL Server provides the FULL OUTER JOIN operator, which allows you to include all rows from both tables, regardless of the presence or absence of values.
You can add a WHERE clause in a FULL OUTER JOIN to get only the rows where there are no matches in the tables. The following query returns only those products for which there are no matches in the sales order.
SELECT p1.Name, p2.SalesOrderID
FROM  TAB1 p1
FULL OUTER JOIN TAB2 p2
ON p1.ProductID = p2.ProductID
WHERE p1.ProductID IS NULL
ORDER BY p.Name ;
FULL OUTER JOIN is not supported in ABAP.  How can you solve this?
Thanks in advance,
