When we try to create a receipt for a particular expense type in ESS Travel & Expenses, we get the follwing error "Tax code Z0 does not exist in the system (T007A)". Upon creating a tax code Z0 it gives the following error "Tax code does not exist in the system (T007A)". When we change the Receipt currency to USD instead of Bristish Pound it gets accepted without the error. It works perfectly fine when expense report created using GUI. The error occurs only when we create the expense report using Portal ESS T&E. I was not able to find anything related to this in the SDN. If any of you could help me out, that would be great.
