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.
