Entering and Accepting Services Performed: Service Entry Sheet 
Use
Entering and accepting services in external services management is the same as a goods receipt posting when procuring materials. However, it consists of two levels.
If the vendor confirms a service, then you can store this service in the system straight away using a service entry sheet. However, you cannot yet enter an invoice from the vendor for the service performed into the system. The prerequisite for this is that you explicitly accept the service entry sheet. For this step, you can make use of the extensive release functionality in ordering. At this point we simply accept the service.

For more information on the use of the release procedure, see the process
Release Procedure w. Classification for Purch. Docs: Customizing.
Entry sheets can refer to the total service specifications ordered. An essential feature of external services management is that you can also create different entry sheets for single service lines.
In the following activity, the service Plan creation from the service specifications of your purchase order should be performed. The service is entered, accepted, and settled.
You can now carry out the following steps for as many outline levels and service lines from the service specifications in your purchase order as you want.
