Internal Orders are updated by event-based postings from different SAP application components, like in Cost Center Accounting.
In Financial Accounting, you can assign postings of G/L accounts of G/L Account Type Primary Costs or Revenue. They will be called primary costs in the following. Examples for primary costs are costs for external services and deliveries to an internal order.
In Materials Management, goods receipts and goods issues may result in primary cost postings to an internal order.
Controlling
To map commitments manually in Management Accounting, you need to enter funds commitments.
Reposting functions allow you to post primary costs to an order. You can post G/L Accounts of type secondary costs (simply called secondary costs) from a cost center to an order with direct activity allocations.
You can record statistical key figures for use as the basis for allocations to your orders and for analyzing your orders.

When you post actual costs to a real order, the costs are initially collected in the order, and you then have the option of reposting or settling the costs to other receivers as required. If the order is assigned to a profit center in the master record, the actual costs are posted statistically to the profit center if Profit Center Accounting is activated as an application of its own.
You can also specify a cost center when you post actual costs to a real order. In this case, the cost center receives a statistical posting of the actual costs. The costs are still managed at order level, but the cost information is also available for analysis at cost center level.
When you are posting actual costs to a statistical order, you must enter a real cost assignment object, such as a cost center, real order, or profitability segment. You can then manage the costs at controlling-object level, but you can analyze them in more detail at order level.
To facilitate data entry, you can assign a real cost center to a statistical order in the order master record. The following two options are available:
The system always uses the assigned cost center. In this case, if you enter a different cost center manually, the system replaces it with the cost center assigned in the order master record.
The system uses the assigned cost center only if no other cost center has been entered manually (deviating posting logic).
