Hi Daniel,
No Expense Arrangements are created for non localized countries. Therefore no expense reporting is possible for such countries.
So, you try this option, Fine-Tune Activity: Expense Reporting - Country ( any of the generic country ) , Click on Edit Expense reimbursement groups.Here use the existing country version but you define the settings as per your requirement for non-localized requirement and define your Expense reimbursement Group.
Once you define this, then create a Expense Arrangement for the employee and the expense reimbursement group that you defined above.
Thanks
