Thanks anyway, I realize that it is quite a strange request, but I think it could be useful to interface the WooCommerce function that allows you to hide SKU with WooTickets.
I’ll try to hide SKU field with some CSS.
Yes, I sell tickets for events organized by other agencies, and I want that they can edit their own tickets in the portal, but I don’t want they can change the SKU (I will use the SKU to identify the supplier).
