some drugs have a different refstrength with same key (cis, dosageform,typecode)
We need to normalize the "refstrength" of each substance in the compo table. To do so, I thought the tuple (cis, dosageform, typecode) would be mapped to the same refstrength, this is not true.
SELECT * FROM COMPO
where cis = 60078263
and typecode = 3
The solution is to add the substance to the v_refstrength_standard table.
