Creating a Purchase Requisition for an External Service 
Use
The starting point of any procurement activity is a concrete requirement. This can be transmitted in the R/3 system from neighboring applications (for example, using maintenance plans from PM or projects from PS), or can be maintained manually. The purchasing document contained in the requirement that represents the beginning of the purchasing process, is also the purchase requisition in external services management. In the following case we assume that you have created everything manually.

Item detail.
.You can specify your service outline on the Service Specifications: Maintain Requisition Specs. for Item screen. The service outline determines the structure of the service to be performed. You can specify up to 4 hierarchical outline levels with as many service items as you want. In the service lines themselves, you can work both with and without service master records. From now on we will limit ourselves to a single level service outline.

General explanation of procedure for one item:
In this process, we assume that only one document item has been created. The result of this is that the procurement process can only take place at one vendor. If, for example, another vendor creates the plan, then you need to create a separate document item in purchase requisition. To make the process less complex, this will not be the case in the following activities.
