You can use Execution Services to enter commitments and actual costs for items for which you plan to use Easy Cost Planning.
The following postings are possible:
Internal activity allocation (for internal activities)
Direct process allocation (for processes)
Reservations (for material items)
Goods issues (for material items)
Purchase requisitions (for material items, external activity items, service items, and variable items)
Purchase orders (for material items, external activity items, service items, and variable items)
Execution Services Customizing

The settings for the Purchase order and Purchase requisition for Execution Services propose the account assignment category of the document. The settings for Reservation/goods issue propose a movement type, but not an account assignment category. The movement type itself, however, defines the account assignment.
To maintain the setting for Execution Services in the Implementation Guide, in Customizing, choose Project System→Costs→Planned Costs→Easy Cost Planning and Execution Services→Execution Services→Define Settings for the Execution Services.
