Source codes 3701 and 3702

I am busy with my 2017 salary structure. My HR department is offering me both codes 3701 and 3702. Will that be allowed in 2017 tax year. Somewhere I read that your cannot do this anymore and must take either the one or the other.

Yes, it is allowed. You cannot have codes 3701 and 3703 together i.e the fixed travel allowance and non-taxable reimbursive allowance together,
