Same barcode but different suppliers

[Callum_Gorham]

I have a simple inventory app with products, stock in and stock out. My products are grouped by supplier. For some of our products we will have multiple of the same thing with the same barcode but from different suppliers, I am unable to add the same product but allocate a different supplier as the barcode already exists. I would also like for the ‘stock in’ products to go to the supplier group that is entered in the form. How would I go about implementing this? Thanks in advance
