SAP Query - SQ01 and SQ02

Hi All,

I have a requirement to user three tables TAB1,TAB2 and TAB3. As TAB3 is cluster table I am unable to use it in Joins. But TAB1 and TAB2 I am able to Join.

Now, after TAB1 and TAB2 are joined then the result how can we make use of TAB3 in the query.

Please share ideas if any.
