User Can't Forward PO

Hi Guys,

I'm new to setting up user in Oracle purchasing.

I have a user who is setup in one of our companies and works fine, but in another where she is trying to create PO's it won't let her choose an authoriser when she goes to approve the PO.

I have checked Her Employee setup in Purchasing Manager -> Setup -> Personnel -> Employees

and Her jobs and Positions but i can't find anything which has her locked down to just one company.

Can anyone tell me where else i need to look?

Thanks

P
