Join Tables On Sorted Values

Is there a way to join tables that have multiple matches to each other (2 records in one table and 2 in another) so that you get 2 records returned instead of 4 with only 1 JOIN ON qualifier?

In our warehouse DB, there is a master location table, an inventory location table, and physical table for counting all product in the warehouse. The master location table has one record per location, but there could be multiple items in that location so my outer join from the master location to the inventory table returns something like:

select M.MASTER_LOC, C.AS ORIG_ITEM, C.ORIG_LOT, C.ORIG_QTY
from
M_LOC M LEFT OUTER JOIN
C_INVT C ON M.MASTER_LOC = C.INVT_LOC
order by M.LOC_CODE

LOCATION ITEM LOT QTY
01-01-A 100 abc 25
01-02-A NULL NULL NULL
01-03-A 200 def 50
01-03-A 200 ghi 50

My problem is adding the third counted inventory table because it could look like anything depending on what we find in the racks:

LOCATION ITEM LOT QTY
01-01-A 100 abc 25 (exact match)
01-02-A 150 cba 75 (Item found)
01-03-A 200 ghi 50 (LOT swapped)
01-03-A 300 def 50 (Item Changed)

My join is returning 4 rows for location 01-03-A which I understand, but I'm wondering if I can sort within the join or make some temp tables so that instead of:

select M.MASTER_LOC, C.AS ORIG_ITEM, C.ORIG_LOT, C.ORIG_QTY, E.AS CNTD_ITEM, E.CNTD_LOT, E.CNTD_QTY
from
M_LOC M LEFT OUTER JOIN
C_INVT C ON M.MASTER_LOC = C.INVT_LOC LEFT OUTER JOIN
E_PHYS_INVT E ON M.MASTER_LOC = E.LOC_CODE
order by M.LOC_CODE

LOC1 ITEM LOT QTY LOC2 ITEM LOT QTY
01-03-A 200 def 50 01-03-A 200 ghi 50
01-03-A 200 def 5001-03-A 300 def 50
01-03-A 200 ghi 5001-03-A 200 ghi 50
01-03-A 200 ghi 5001-03-A 300 def 50

I'd like to just end up with 2 lines sorted by location, item, lot, qty so I can see that there is a problem with that location.

LOC1 ITEM LOT QTY LOC2 ITEM LOT QTY
01-03-A 200 def 5001-03-A 200 ghi 50
01-03-A 200 ghi 5001-03-A 300 def 50
