Before customizing the Master Data in SAP Plant Maintenance and Customer Service

You must have defined the plant maintenance organizational structure in your system before you proceed with customizing.

This involves maintaining the planning plants and maintenance plants as organizational units.

A distinction is made in Plant Maintenance between planning plants and maintenance plants.

The Maintenance plant is a plant where you can manage technical objects and the work centers responsible for carrying out the work in a maintenance plant.

The planning plant is a plant where you define maintenance task lists, carry out materials planning on the basis of the BOMs in task lists and perform maintenance orders, manage and schedule maintenance plans, enter maintenance notifications and process maintenance orders for the associated maintenance plants.

The recommendation is that yo should always use planning plants when maintenance planning is to be carried out centrally in one plant for several plants. If each plant is independent from a maintenance point of view, each plant is then also a planning plant.

Please note that there are many areas that will overlap with the implementation of components 'MM' (Materials Management) and 'PP' (Production Planning) when you are customizing the system for Plant Maintenance.

If you discover settings that are not relevant to Plant Maintenance, you should only change or delete these after consultation with the appropriate project groups.
