this will return the past 15 business days (meaning all days except Saturday and Sunday)
including today.


SELECT *
  FROM (SELECT *
          FROM (SELECT SYSDATE - LEVEL - 1 d
                  FROM DUAL
                CONNECT BY LEVEL <= 21)
         WHERE TO_CHAR(d, 'Dy') NOT IN ('Sat', 'Sun')
        ORDER BY d DESC)
 WHERE ROWNUM <= 15

You could then use this to join to your other table

Alternatively you could generate a range...

SELECT min(d), max(d)
  FROM (SELECT *
          FROM (SELECT SYSDATE - LEVEL - 1 d
                  FROM DUAL
                CONNECT BY LEVEL <= 21)
         WHERE TO_CHAR(d, 'Dy') NOT IN ('Sat', 'Sun')
        ORDER BY d DESC)
 WHERE ROWNUM <= 15;

and then use this where your table between those values; but then you'd also have to exlude Saturday and Sunday using a condition similar to that shown
