Is it possible for a NetSuite admin to remove an item from a customer's cart? Cart contents are visible when viewing the Customer/Lead record, but I don't see any obvious methods to adjust its contents.

I don´t think so. There is a "Login as customer" functionality but per what I recall it just logs you to customer center as if you were the customer.

Ah, clever. I'll give that a shot. Thanks!

I tried doing this awhile back with code. Iirc, the cart table is locked down.

That's too bad. 😞 I found a solution, but it's VERY MANUAL. Where I attach a fresh contact to a customer account, then login with that fresh contact. And because I'm using customer-scoped carts it's possible to remove items.
