Breakdown Maintenance

Scenario:

Sometimes, the maintenance work centers need to take immediate action, due to unexpected machine breakdowns, accidents or other malfunctions, even though neither the type nor the scope of the activities required are known.  Maintenance of this nature is referred to as Breakdown Maintenance.

In SAP Plant Maintenance, we can have a process where a production manager or requester will fill out a manual work order form ( ideally the manual form should be identical to the system generated form in SAP ). The technician(s)(mechanic or groups of mechanics) will now execute the job indicated in the maintenance work order form and his findings if any.After all the work is being done, the requester will acknowledge the repairs/work done by the technician. On the next day,the maintenance planner will encode all findings and transactions (like spare parts used, actual duration of the work) in SAP with date based on the Manual Work Order form and performs the technical completion of the maintenance order(TECO). Finance department will run a periodic settlement in which it will post the proper charges to the cost center. After all items are being settled, they fill perform the business completion of the maintenance work order(BUCO) to close the maintenance work order.

MAINTENANCE STRATEGY & TASK LIST

The Maintenance Strategy consist of several maintenance packages. It is the scheduling rule for preventive maintenance.

The Scheduling Indicator determines the type of scheduling :

Examples:

– time-based

•     time-based with key date

•     time-based as per factory calendar

•     performance-based

A Maintenance Strategy can be assigned with Maintenance Packages.  The packages of a strategy can have different cycle units (for example month, year).  However, they must always have the same dimension (for example time).

Maintenance Packages define how often certain operations are to be performed.As Part of the Maintenance Strategy,  Maintenance packages can be assigned to the operations of a task list.

The Parameters of a Maintenance Package are the following:

– Package number

   – Description

   – Cycle length

   – Unit of measurement

    – Hierarchy

When two packages fall due at the same time, the hierarchy determines which package    is carried out.

    – Offset

The offset determines the first due date of a package.

– Preliminary/follow-up buffer

The preliminary and/or follow-up buffer defines the tolerance of the envisaged start and end dates of a package.

Maintenance Task Lists can be created with preventive maintenance in mind.  The following steps are required to prepare tasks lists for use in Strategy Maintenance Plans. Where a Maintenance Strategy is defined in the Task List Header.

The different Operations of the task list are then assigned to Maintenance Packages to define the frequency at which the operations need to be carried out.
