You select in your statement for plantcode = '1' but seem to want other 
plants - I'll assume that is incorrect.

I would start out with joining the 3 tables on plant code and part 
number, then group by those fields, plus the bin type -

select a.plantcode, a.partno, b.bintype, count(*)
from tablea a join tableb b
on a.plantcode = b.plantcode and a.partno = b.partno
join tablec c
on a.plantcode = c.plantcode and a.partno = c.partno
where c.shiptype = 'PS'
and a.scyy||a.scmm||a.scdd = '201129'
group by a.plantcode, a.partno, b.bintype

You could refine it some with a couple table-expressions, either correlated or nested - one would be a select from a where a.scyy, etc. The other would be select from c where shiptype = 'PS' - this might make it run faster.

Not tested - just from memory here!

Hmmm?
