Let me try to explain
i have several suppliers, their price lists a based on specific product names and sku.
Canon PIXMA MG3550, CH8331B006AA
1, supplier uses full part no CH8331B006AA
2nd supplier uses part of parno 8331B006
3. uses model name Canon MG3550.
4th uses internal fixed code ,nuber , 120445 for example
so automated product import is usles
but with small interevntion, for example if we are able to do custom attribute mach
i could assign custum atribute ( supplier1 sku, supplier 2 sku )
than product identification based on this attributes per supplier would be easy.
offcourse it need to have some rule for import control to if qty on supplier stock is >0, and price lower than current
