Netsuite is giving me this error message. If I am not mistaken, this is a saved search error. This should not appear since I am only viewing the sales order list from Transaction>Sales>Enter Sales Order>List. I also have the Admin role.

true, but you may be set up to use a custom saved search as your default list view that contains the error

I tried logging in using a different role and different account but the exact link/list showed results. This is odd.

you are trying to group Amounts; instead, you should sum them. Try Summing
