Maintenance Plant

In the oil field services, we are using EAM to manage the Rig Maintenance. A Rig is a massive structure and we have built a complete Floc and equipment structure.

I am wondering if I need to maintain a maintenance plant for the functional loc and equipment. since it is out in the field and has not reference to any plant in the system.

we have 1 Plant from which maintenance for these rigs are carried out. (This is our maintenance planning plant)


My question is- What if I don't maintain a maintenance plant in the structure? Will i face any issues down the line in reporting?

    Hi CHAN KAR,

    If you implement SAP EAM, the company code, controlling area and plant are usually already defined. This is because they were defined when other applications such as CO,MM,SD & so on were implemented. The plant from a maintenance perspective is the most important organizational unit for plant maintenance. A plant is responsible for planning maintenance activities.

    Coming to your query, first plant is assigned to a company code which is the organizational unit foe which a complete set of accounts can be drawn for the purposes of external reporting ( balance sheets, profit & loss statements).So, when you assign a technical object to a maintenance plant, you also automatically assign its company code in the background.

    Secondly, the controlling area is an organizational unit within a company. It is used to represent a closed system for cost accounting purposes. When you assign a technical object ( equipment or functional location) to a maintenance plant, you not only create its company code, but also determine its controlling area.

    For above reasons you need to maintain maintenance plant or else as said you will face issues down the line in reporting.

    Hi Chan Kar,

    Plant is logistic unit and it is assigned to Company Code. All the transactions related to finance taking place in plant are direct posted to company Code level. That is used for external reporting.

    Company code is assigned to Controlling area for Cost Center Accounting .Generally this is 1:1 relationship between Company Code to Controlling area.

    Each Company Code uses specific GLs from Chart of account.

    Corresponding to these GLs, Cost Element has been defined. Cost Element are used in Cost Center Accounting. It works as cost carrier in internal reporting.

    So yes, you will face issues in External & internal reporting.

    Hi Chan,

    Your Maintenance planning plant will be resposible for planning and reporting etc.

    In SAP, we do not create Maintenance plant separately, this is assigned automatically when you define plant. You will only assign the Maintenance planning plant to Maintenance plant.

    Once maintenance is Centralized or De-Centralized is finalized, then you define the Maintenance planning plant under enterprise structure and correspondingly assign the planning plant to the maintenance plants (which is defined in MM already).

    In your case, if you do not want to have a new plant for this rig, then choose your Maintenance planning plant and Maintenance plant as one. In future if there is a new rig is commisioned, then you can assign the same Maintenance planning plant.
