SAP PM Preventive Maintenance Overview and Configuration

Business Process Overview :

Preventive maintenance is the pre-planned maintenance activity that performed while the equipment is still working, so that it does not break down unexpectedly. Preventative maintenance is planned so that any required resources are available.

Preventive Maintenance is also used to avoid system failure other objects, which - in addition to the repair costs - often result in much higher costs subsequently owing to production breakdown.

There are many benefits in using preventive maintenance within your company. It is the generic term for systematic inspections, detection, Correction for which the time and scope of the work can be planned in advance.

You can use maintenance plans to describe dates and the extent of preventive and inspection maintenance tasks which can be planned for technical objects. You can ensure that your technical objects are always maintained on time and in this way, ensure that they function optimally.

Preventive Maintenance :Types

 Time Based Preventive Maintenance : 

In time-based preventive maintenance, the maintenance tasks are planned and performed depending on the time-dependent intervals determined. Example : There are vehicles(equipment) which needs to be serviced after different-2 cycles like1 month, 4 months, 6 months, 12 months..etc

 Performance Based Preventive Maintenance : 

In Performance Based preventive maintenance performed based on Counter Reading. Example :  There are vehicle which needs to be serviced after running 5000 kms, 10000 kms and so on.

Condition Based Preventive Maintenance :  

In the case of condition-based maintenance, maintenance activities are always performed when the measuring point of a technical object has reached a particular state or outside a specific value range. For example, a thread depth below 15 mm or temperature higher than 85 C.
 
Strategy and Task List

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

Maintenance task lists describe a sequence of individual maintenance activities which must be repeatedly performed within a company. Task lists eventually become the operations within the maintenance order that is generated through the Maintenance Plan.

There are three types of task lists that can be distinguished from one another using indicators:

• Equipment Task List
• Functional Location Task List
• General Maintenance Task List

SAP PM Measuring Point, Counter and Measurement Document Configuration and Process

Overview : 

Documenting the condition of a particular object (Equipment) is of great importance in cases where detailed records regarding the correct condition have to be kept for legal reasons. This could Involve critical values recorded for Machine or  environmental protection purposes, hazardous working areas that are monitored for health and safety reasons, the condition of equipment in hospitals (intensive care units), as well as measurements of emissions and pollution for objects of all types

 

Measuring Point :

 In SAP System Measuring points describe the physical locations at which a condition is described , ( For example, Temperature,  Pressure on a Boiler, Dash Board or  Odometer of a Vehicle The characteristics associated with the measuring points which record the value can only be numeric characteristic.

 Measuring points are located on technical objects, in other words, on pieces of equipment or functional locations. For every measuring point there should be some characteristics to measure the reading.

Purpose :
For better monitoring of capacity utilization, maintenance objects have measuring points and counters to record flow quantities or operating hours, for instance. Measurement and counter readings are stored in the system in the form of measurement documents.  These documents are the basis for performance-based maintenance planning.

Counter :

Counter is type of measuring point, where a continuous reading is recorded (e.g. Kilometer, Hour Meter). Counter readings are taken at counters at particular intervals and in particular measurement units. 

The above Picture given (Kilometer) is treat as a counter where Kilometer reading we can take from certain intervals.

Characteristics and Class :

Characteristics : Specification or Quality belonging to a Technical Object (  Equipment, Functional Location )Characteristics are used to store additional data or condition value.

Class : A Class is a collection of Characteristics. Class is assign to Equipment or Functional Location

Step 1 : Create Characteristics ( T Code : CT04)

Step 2 : Create Class ( T Code : CL02)

Step 3 : Assign Class to Equipment 

 Step 4 : Create Measuring Point - IK01 (Counter Base)

Step 5 : Create Measurement Document  ( T Code : IK11)

SAP MM - FI Period Open and Close Error and Solve - Message no. M7053 and F5286

T Code : MMPV - Close Period ( For Error  Massage M7053)
In MMPV you can execute period closing up to the end of the current fiscal year. The period closing program updates the administration record, thus ensuring that the stock data of the material master are updated.
If, for example, you want to close your periods up to 10/2014, you are not allowed to post values in 08/2014. Therefore, if you still want to make postings in period , you should execute period closing only for a maximum of t+1 periods.

Then Execute

MMRV - Allow posting to previous period. (You Can Check the Present Open Period , but don't make any Change)
This transaction allows you to view current period and change setting for posting to previous period.

OB52 - Change view "Posting Periods: Specify Time Intervals" ( For Massage F5286 )
(Need to Change period while showing this Error)

Solve by OB52 (Update Required Period , Its can generate Transport Request)

Then SAVE. Error will Solve.

Unprocessed future change recs for order " " prevent del. flag/completion massage no. CO688 Error Solving Process.

This Error showing while make to Order Business Completion after TECO.

Solving Process..

 Click on Reprocessing incorrect goods movements. Set The Plant and Order like below screen and
Execute

Select the line and Delete.

Also you may have run the following transaction to identify errors: 

COGI - For post processing goods movements 
CO1P - Predefined Confirmation Process
IW46 -  For post processing confirmations from CATS
COFC - For post processing actual costs
COGI - For post processing goods movements
