Perhaps my exposure was not optimal
cmq try to re-explain my problem by having a product such as 711 tonnes and can be used on various products
and not just one.
example
Brand epson
subcategory: Epson D78 (printername)
added to the product (t711)
this works
t711 but if this is used by several printers such as 20 printers
how could I do?
