Creating and Budget Checking Travel Authorization for next year

Dear All,

We have currently implemented Travel and Expense module for our client and now we are faced with an issue as described below:

We have our budget year from 01-01 to 31-12. Now the client wishes to raise Travel Authorization in the month of December for Travel dates in January. We have already loaded the Budget for 2018 and the Chartfield combinations for 2018 as well. The Travel Authorizations have the Budget Year as 2018 entered for each expense line but when we try to Budget Check the Travel Authorization in December, then the TA is running into Budget Exceptions, the reason being on the Budget Chartfields, the Budget Year is 2018 but the Budget Period is 2017 itself.
