SAP PM

Organization structure of SAP PM : 

1) Client :  It is the highest hierarchical unit in the SAP system. All areas of an organization that are to be integrated into SAP, should be included under one client.

2) Controlling area : An organization unit within a company used to represent a closed system for cost accounting purpose.A controlling area may include single or multiple company codes that may use different currencies. These company codes must use the same operative chart of accounts. All internal allocations refer exclusively to objects in the same controlling area.

3) Company Code : It is the smallest organizational unit of Financial Accounting for which a complete self-contained set of accounts can be drawn up for purposes of external reporting. This includes recording of all relevant transactions and generating all supporting documents required for financial statements.

4) Maintenance Plant : A Maintenance Plant is an organizational unit within Logistics, serving to subdivide an enterprise according to procurement, maintenance, and materials planning.

5) Maintenance planning plant : Maintenance planning plant is a logical location where the maintenance activities on technical objects are planned. The Maintenance Planner Groups who plan and monitor the maintenance activities are defined at the maintenance planning plants. Maintenance planning plants determine if the maintenance planning is centralized, decentralized or partially centralized.

If maintenance is centralized, then there would be one Maintenance Planning Plant for all the Maintenance Plants. if it is decentralized, then there would be a Maintenance Planning Plant for each Maintenance Plant. if it is partially decentralized, then there would be Maintenance Planning Plants, looking after a few Maintenance Plants each.

Business Process & master data Impacts : 

a) Material Planning based on maintenance task lists and maintenance orders
b) Management and scheduling of maintenance plans
c) Creation of maintenance notifications
d) Performance of maintenance orders
e) Location-wise analyses on different performance parameters like costs, downtime's, breakdowns etc. are possible at the Planning Plant level.
f) Definition of technical objects, maintenance task lists etc.

6) Locations : Location is a place in a maintenance plant at which a technical object is physically located. It allows a plant to be classified according to spatial or situation criteria.
Locations are used for informative assignment only. We can only use Locations as a match code or as parameter criteria in reporting.

7) Plant section : Plant sections are processing units/ production areas within a maintenance plant. These are subdivision of maintenance plants. Machines or sets of machines that are represented in the system as pieces of equipment or functional locations are installed in plant sections.

We can indicate the place for which a maintenance task was requested with the plant section. We also, can establish a contact person for Plant Maintenance using the plant section. Plant sections are assigned to Maintenance plants.

8) Maintenance planner groups : A group of employees responsible for planning and processing maintenance tasks in a plant. Planner groups or Maintenance Planner groups must be defined separately for each planning plant. Depending on the size and structure of your company, a maintenance planning group may be an individual department (for central work preparation), a group of Technician or a workshop.

9) Work Center : Work Center is an organizational unit that defines where and when an operation must be performed. The Work Center has an available capacity. The activities performed at or by the Work Center are evaluated by charge rates, which are determined by Cost Centers and Activity types. Centers and Activity types are defined and detailed in Finance & Controlling Module. Work Centers can be: Machines, People, Production lines or Groups of craftsmen.
