T&E for AX2012 R2 CU6 - How to configure GL posting for project related expenses?

I have configured Travel and Expense Module and everything is working correctly except for GL posting. When I post an expense report I can see those expenses on my invoice proposal and on the vendor payment form but nowhere in GL. I have set expense category in T&E the same exact way as it is in AP and the payment method to "worker" for "offset account type". What am I missing here? I was following 80429A_ENUS_EXP from partner source library.
Thank you.
