Thanks ajay,
but my query is, if i keep Currency type 10 and keep INR at controlling area level.
below are the implications:
Eg. On 1st january i posted Salay Rs. 10000 on cost center 100001 at that time USD rate is 66
at that time if i run cost center report system will show Salary amount 151.52 USD (10000/66)
On 10th january if i posted again salary Rs.10000 on cost center 100001 at that time USD rate is 60
now if i run the cost center report system is showing salary amount USD 333.33 (i.e.20000/60) and its ignoring the earlier translation rate and showing in the new one (i.e.60)
But we need system to show USD 318.18 (i.e 151.52 which is calculated on rate 66+166.66 which is calculated on rate 60 ).
Please suggest me which currency type to follow if i want to suffice the above requirement?
