wELL i HAVE A QUERY FOR THAT BUT ITS KINDA SLOW ONE.. AND what I guess is that u want for same bidid.. (if u want for load just change the names of the columns)

select load from load a, load b
where a.load = b.load and months_between(a.startdate,b.startdate) <= 6

I think this should work.

Actually the logic is to do a self join and then find months between. I just am not able to understand your tables structure and primary keys.
Do let me know or else I think u can figure out the SQL urself
