Using Multiple account assignment, You can distribute costs across accounts by percentage, by quantity, or by value.

When data is transferred to an SAP back-end system, the cost distribution by quantity and value is not always retained. Instead, the system changes the cost distribution type as follows:

Cost distribution by quantity: Service items are converted to percentages.

Cost distribution by value: Material and service items are converted to percentages.

Flexible type of account assignment category The account assignment category only defines the type of account assignment data that is entered in the generic fields for account assignment information.

The following account assignment categories are available:

Asset

Cost center

Network

Order

Sales order

WBS element

In the SAP back-end system the account assignment category is part of the item data, whereas in SAP SRM the account assignment category is managed at account level.
