TA dated May 2016 Enc 1000; No-Reimb. Airfare 200.00 pd by Pcard Exp acct.; ER not entered until 201

I am working in a KK or budget control environment. I have a budget for travel of $1000.00. Created a Travel Authorization and encumbered in 05/2016 for $1000.00. The Airfare for $200.00 is non-reimbursable and paid by pcard in PS Payables as an expense. The trip doesn't happen until 10/2016 and the Expense Report is not created until after the trip which is now in the FY 2017. Since I already encumbered the whole budget amount, would the pcard failed budget check when creating the expenditure for this budget or will the system reduce the encumbrance to $800.00 and allow
