Yes, but why do you want to do that? It looks like you have set up a
one-to-many relationship between stock and product (i.e., each stock record
has multiple associated product records). Is that what you want? If so, it
does not really make sense to store data from a product record in a stock
record, because there can be multiple products per stock, in which case,
which product's qtd value gets stored in the stock record? It would help if
you explain what you are really trying to achieve with this design
(see http://xyproblem.info/).
