I am trying to pre-approve sales orders inside of a before submit hook on create of a sales order. By default, our order status is in the "Pending Approval" ('A') state.

Once I determine that we want the sales order approved, I try to set it the Pending Fulfillment ('B') state.

    nlapiSetFieldValue('orderstatus', 'B');

For most of our users, this worked fine. For some, they would get this error:

"INVALID_KEY_OR_REF Invalid orderstatus reference key B" while trying to pre approve a sales order.

I thought it might be a role issue, but I flipped the script to run as administrator, and they still had the same issue. I've also set my role to be the same as theirs, and I can't recreate the issue.
