Error -4077: You have sales for this item.

Hi Brody_M,

Appreciate for providing the error, super helpful! This typically happens with items that were previously set as inventoried and already have sales history. Even if you later untick I inventory this item, those items still behave like inventory items in the background, so importing changes for them can trigger this error.
 

This isn’t something you can fix from the front end, but our support team can arrange a back‑end script over your file to clean this up. You can reach our Live Chat team via our virtual assistant, MOCA or by submitting a support case via MyAccount.

Regards,
Earl

Thanks for the reply, Earl. 

I have updated them manually as it was only a few. I will keep this in mind for next time though.
