Answer 1

What is the difference between "cost object" and
"cost center"? Please see the context below. It says
that cost object and cost center are not the same.
Cost objects :
The units of output resulting from the value-added process with which costs are identified according to how they are incurred.
Cost objects can be independent entities (called cost object IDs), or they can represent other entities (such as orders or projects).
The functions of preliminary costing, simultaneous costing, and final costing can be performed on cost objects.
The following cost objects can be used in the SAP System:
Product cost collectors
Production orders
Process orders
Cost object IDs
Sales order items
Cost center is an controlling object and Cost object is also one of the controlling objects. Other controlling objects are
Cost centers (for account assignment of costs)
· Orders
· Projects
· Networks
· Make-to-order sales orders
· Cost objects
· Profitability segments
· Real Estate Objects
· Business Processes
Primary costs are transferred from external
accounting and classified according to managerial
accounting perspectives. If the primary costs are
direct costs, then they are assigned to cost objects.
Need not be. They can be assigned to any of the controlling obejcts. Generally for primay costs we use Cost center as the controlling object. we can also use IO in which case u have to resort to peridic or full settlement. Apart from Cost center other objects require either periodic or full settlement of the cost collected.> If they are overhead costs, then they are assigned to
cost centers or overhead cost orders. The system then
allocates them using internal allocation techniques,
according to their source
Cost centers or other objects collects theprimary costs and then can be allocated to other objects based on the sender receiver relationship u define.
