I don't have GTIN and MPN number, but have the brand name.
I have the brand name, but no GTIN and MPN number. Some of the experts suggest to fill in "False" in "Identifier exists" category. However, the system says this causes error. I cannot leave 2 out 3 blank. In other words, I must leave brand name blank as well. Or I must fill out the gtin or mpn. What should I do to fix the problem right now?
