Internal Order
An internal order is used to accumulate cost for a specific project or task for a specific time period. An internal order is therefore used for a short period with a specific deadline.
Your internal order will usually settle to cost centers (and not visa versa) according to the settlement rule in the order setup.
An internal order can therefore be used to group all the expenses incurred to plan and hold a conference over a 3 month period. The order can be settled on a monthly basis to cost centers. When the conference is finished the order can be settled finally. The cost of the conference will then be spread over 2 or more cost centers, but can be viewed in total on the internal order when needed.
Internal orders can be used for the following purposes:
Monitoring the costs of short-term jobs
Monitoring the costs and revenues of a specific service
Ongoing cost control
Cost centers are not for specific job. e.g If you have open Trade-fair / exhibition (1 month period), then to allocate cost, you can use Internal Orders (Say IO) you can post to IO, and from their to various cost centers. If management were to ask you the cost of that exhibition, Internal Order will help you

It cannot be defined as statistical but in transactions it may become as per other co objects.You will be able to find out the performance of the cost center using activities and plan values with actual value. This is lowest cost object in SAP. This will become a statistical object when you allocate the cost to other higher objects. Cost can be allocated to other cost centers or co objects but not fi objects like GL,assets, inventory etc. can be defaulted in transactions through cost element. It cannot be a cost object for a revenue element, revenues are always taken for other higher CO objects. No budget functionality is available but planning functionality is available and is always measured for a year in business.
