Enable the option of Entering the limits for expenses based on various parameters like per/day, per/person, etc. This will be helpful when 2 person are involved in expenses.
For Example, me and my colleague are travelling and staying in same room i.e. double occupancy. The expenses would be claimed by me, the limits which are currently set in the system is per submission, so it will always show policy violation. Per Diem can be a used here, however per diem is fixed option, wherein our case it would be less than per diem amount.
