Service Purchase Requisition
You can manually create purchase requisitions for lean services using the Manage Purchase Requisitions - Professional app. You can convert these service purchase requisitions to purchase orders using the Process Purchase Requisitions (V2) app. You can create purchase requisitions with item hierarchy, by grouping items, services or materials. For instance, if you are purchasing services and materials for different departments of a company, you can use item hierarchies to group the items by department. To use the item hierarchy you need to switch to hierarchy view on the items tab/table in the Manage Purchase Requisitions - Professional app. After you switch to hierarchy view, you will not be able to change it back unless all items are deleted.

The Process Purchase Requisitions (V2) app only supports functional items (service or material), it does not support conversion on item hierarchy level. If you use item hierarchy in your purchase order, you need to use the Assign and Process Purchase Requisitions app to convert the purchase requisition to purchase order. Assign and Process Purchase Requisitions app only supports selection of a single item hierarchy at once, so you need to create item hierarchy in separate purchase requisitions.
Same as in Model Product Specifications, to use item hierarchies in purchase orders you must activate the item hierarchies for purchasing using the configuration Activate Item Hierarchies in Purchasing.Service Procurement Using Service Order

Business users can trigger the creation of a purchase requisition for planned lean services directly out of a service order. You can use the service-order item as an accounting object for the procurement of lean services.
A configuration expert can configure a workflow so that the service order responsible can approve the respective service entry sheet. After approval, the confirmation for the service provided is automatically triggered.
- Ability to trigger confirmation for the service provided by an external service provider in one step.
- Possibility for the person responsible for the service order to approve the service entry sheet.
- More effective third-party service procurement process, starting from the automatic creation of the purchase requisition out of a service order to the confirmation of the provided service.
You can check the solution process Project Control - Resourcing and Procurement (4RF) in the process navigator to learn how to trigger the procurement of services and materials when a service is required for a product.

Instead of being triggered by a service order or a manually created purchase requisition, the process can also start directly with the creation of a purchase order for the required service. It may also be subject to approval if required. You can use flexible workflows to define an approval process according to your business requirements.

As a purchaser, you can manually order materials and services using the Manage Purchase Orders SAP Fiori app. You can create purchase orders with standard items or limit items to procure lean services.
- Create a new item for planned lean services:
- You have two options for creating planned service items: You can either enter master data under the Material field (the master data must be of the product type group Service), or you specify the required services by entering a free short text and choosing the product type group 2 (Service).
- You can influence the process control of service items so that neither a service entry sheet nor a goods receipt is required and an invoice can be posted immediately.
- If you decide that a service entry sheet (and a goods receipt) is required, the account assignment category of the purchase order can no longer be changed once a service entry sheet has been created.
- You can display the confirmations for lean services, including start date, end date, and service performer.
- Create limit items for unplanned lean services:
- You can define a value limit for unplanned services, that is, services that cannot be specified in detail at the time of ordering. This also applies to services that are of such low value that you want to reduce the administrative effort involved in processing POs and follow-on documents. You can define both an expected value and an overall limit. For a limit item, you must enter a time period. The services can be specified later in the service entry sheet where the exact services and their price and quantity can be recorded. Otherwise, you post the invoice directly with reference to the PO.
You can enter a purchase contract number in an enhanced limit item for lean services to restrict the services recordable in the service entry sheet.
Use the service order integration
A purchase order with the account assignment category Service Order is initiated by a service order from Service Order Management.
If the automatic creation of purchase requisitions from service orders is activated in the master data of the relevant material or service, the data of the service document is automatically maintained by the system. Otherwise, you as a purchaser can maintain the data of the service document in the purchase order.
As a purchaser, you can also create purchase orders for lean services using the advanced app Create Purchase Order - Advanced. The table shows the apps and corresponding item categories to create purchase orders for lean services:
