SellerAmp SAS BQool Integration: Editing SKU, ASIN & Fulfilment in Listings

Why can’t I update some fields for an existing BQool listing in SAS?

The SKU, Marketplace, ASIN, Fulfilment, and Item Condition fields can only be set in a new listing in the BQool integration, but will not be editable in an existing listing; to fix this, you would need to delete the existing SKU from BQool and add the listing again.
