Internal Order Settlement to One Receiver 
You settle the costs collected on an internal order to one cost center, one G/L account, or one business process using one settlement cost element.
Caution
If you have entered a general settlement rule for an internal order, you cannot use the kind of order settlement described here.
Prerequisites
In the settlement parameters, you need to assign a settlement profile to the internal order. As you cannot maintain settlement parameters when you settle to one receiver, you can store the settlement profile in the order type. Otherwise, you need to create the internal order with the help of a reference order, which has a settlement profile assigned to it.
Before you can settle an order, it must have a status that allows the Settlement business transaction. If you posted revenues to internal orders, you cannot settle them to cost centers.
Features
Note
The system always uses the document type "SA" during settlement to one receiver. If you wish to use another type of document for your order settlement, use the more comprehensive settlement.
You can find more information on more comprehensive settlement in the SAP Library under

CO Controlling Internal Orders Settlement 
Receiver | Settlement Cost Element | Credit for the Order | Debit | Settlement Type |
Cost Center | Category 21 (internal settlement | Under the settlement cost element | Takes place on the cost center under the settlement cost element | Settlement is made by period: The system always only calculates the cost from the period specified during settlement. |
G/L account | Category 22 (external settlement) | Under the settlement cost element | Takes place on the G/L account | The system executes a cumulative settlement of all the costs incurred on the internal order (up to, and including the settlement period). To execute settlement by period, you must settle the order in each period. |
Activities
To enter the settlement receiver and the settlement cost element, choose the Period-end closing tab page in the internal order master data. Then, in the Settlement to one receiver group box, enter the settlement cost element and the receiver for the costs collected on the order. When you settle the internal order, the system automatically creates the corresponding settlement rule and hides the Settlement Rule pushbutton.
To settle internal orders, choose:
Individual processing
You use individual processing to control the settlement of individual internal orders.
Collective Processing
Collective processing is normally used as part of period-end closing to trigger background processing. This is when you want to process a large number of internal orders.
Line item apportionment
You only require line apportionment for capital-investment measures. You can find more information on line item apportionment for capital-investment measures in the SAP Library.
Collective Processing
In the initial screen for collective processing, make the following entries:
Selection variant
Parameters
Processing
To select internal orders, enter a selection variant.
You can define selection variants in customizing by choosing Controlling Internal Orders Order Master Data Selection and Collective Processing Define Selection Variants , or by choosing SelVariant
Note
These selection variants are also used elsewhere, such as collective processing of internal orders.
You can refer to order master data fields and order groups when making a selection. You can also determine classification characteristics during selection. However, this is not a good idea when you are processing large numbers of internal orders (more than 10,000).
You can find more information on the Parameter and Processing Control group boxes, in Carrying Out Settlement, located in the SAP Library under Financials CO Controlling Internal Orders Settlement
