What document combines a technical object, service contract, and service order template for planned service?

The correct answer is a maintenance plan, as it serves as a comprehensive document that integrates several key elements necessary for managing planned services. Specifically, a maintenance plan encapsulates a technical object, which represents the asset or equipment that requires maintenance. It also includes the associated service contract that outlines the terms of the service agreement and a service order template that details the specific tasks needed for regular maintenance or service activities.

This holistic approach allows for efficient scheduling and execution of maintenance tasks while ensuring that all contractual obligations are met under a single framework. The maintenance plan is essential for organizations that aim to maintain operational efficiency through proactive service management and adherence to service agreements.

In contrast, a service contract solely focuses on the agreements made between service providers and customers, without detailing the technical aspects of the equipment involved or the planned activities. A service invoice pertains to billing after services have been rendered, while a sales order is related to the sale of physical goods or services rather than the maintenance of assets.
