SAP Plant Maintenance
Performance Based
Preventive Maintenance
based on Measuring Point
(Engine Hours)
in CT04, create Characteristics Z20_HOURS for Engine Hours Measuring Point
Numeric Data Format
5 numbers with 0 decimals
UOM = “h” (for hours)
Mandatory
Create new Equipment ZEQ20 with a Counter Measuring Point using Characteristics Z20_HOURS
Enter necessary data and GOTO “Measuring points/counters”
Enter the new Characteristics Z20_HOURS, click “Counter” and
click “Details” ICON
Counter overflow Reading “999999” (max Counter number),
Estimate 20 hours a day (estimate work days 20 days a month), therefore 20 x 20 x 12 = 4800 per Year for the Annual Estimate.
The Preventive Scenario will be:
1200 hours (around 3 months) - Inspect & Lubricate
2400 hours (around 6 months) - Change Parts
4800 hours (around 12 months) - Full Service
Measuring Point 12042 created
Initialize the Measuring Point to 0 hours as it is a new Equipment
Overall the format to 0
note 0
SAVE
Measurement Document created for the Measuring Point initialization
Measuring Document entered for the Equipment can be view from the MP/Counters screen
Since there is only one Measurement Document, click this button

Create new Strategy “ZS20” for Performance-based Preventive based on “Engine Hours” for the following Cycles:
1200 hours (around 3 months) - Inspect & Lubricate
2400 hours (around 6 months) - Change Parts
4800 hours (around 12 months) - Full Service
Scheduling indicator = “3 Activity” (for Counter-based) with Strategy unit “h” (must be same UOM as the Characteristics for the Measuring Point)
Call horizon “2 DAY” (meaning Maintenance Order is called 2 Days before its Due Date, Factory Calendar is Optional. Next, Double-click “Packages”
Create new Strategy “ZS20” for Performance-based Preventive based on “Engine Hours” for the following Cycles:

Create a Strategy-based Maintenance Task List “PM20Z”
For Strategy-based Preventive Maintenance, the Maintenance Strategy is Mandatory

Press ENTER
Map the Operation to the correct Cycle from the Strategy “ZS20”
check Maintenance Plan Category “PM”
Maint.plan cat. set with Call Object “Maintenance Order or Service Order”
Indicator that you use to specify that the release of scheduling for a maintenance plan is also documented with a change document.
Indicator which specifies that changes in certain predefined fields in the order are to be recorded in a document.
Indicator: Separate completion of maintenance call date
User can use this indicator to influence the maintenance processing process. For example, user can prevent that every employee who can complete orders and notifications can also influence the scheduling of maintenance plans through the data.
If blank, system use Internal Number Range assigned to the Maint.Plan Cat. “PM”
Maint.plan cat. “PM” (with Call Object as Maintenance Order”
Enter the new Strategy “ZS20”
Enter an appropriate Short Text
Counter from the Equipment is proposed
Measuring Point from the Equipment is proposed when the UOM (“h”) matches the UOM in the Strategy “ZS20” assigned
The Task List assigned must have the SAME Strategy as the Maint.Plan Header
Only when the Task List Strategy matches the Maint.Plan Strategy that the Cycles from the Strategy are Populated here
Strategy in the Maint.Plan Header CANNOT be Changed
Call Horizon is defaulted from the Strategy (or manual entered here)
Let’s say the Maint.Plan is valid for 3 years
Let Start Counter Reading is 0 (for new Equipment)
Internal number for Maint.Plan created
Online schedule the Maint.Plan
Current Counter Reading is 0
Packages as per the Strategy
Call dates are 2 days before the Plan date (Due date) due to the “Call Horizon”
All Packages on HOLD as there are NOT DUE yet
To simulate the Due of Package “12” (1200 hours), we shall enter a Measuring Document as 1210 hours
Enter next Counter Reading is 1210 hours in order to simulate the 1200 hour Cycle is due for Maintenance
Current Total Counter Reading is 0
Enter 1210 and press ENTER
New Total Counter Reading
Measuring Document for 1210 hours created
check Measurement Documents created for the Equipment
There are exactly 2 Measurement Documents created,
here I select the latest MeasDoc. and click “Measurement Document”
Notice, the latest Counter reading exceeding Package “12” cycle of 1200 hours
Package “12” (1200 hours) cycle is now DUE, and the Equipment is DUE for Maintenance
Note Call Date EMPTY, SAVE will Call a Maintenane Order
Access the Maint.Plan in IP10 to check the Called Maintenance Order
Planning Data from the Maintenance Item was used to create the Maintennece Order
Only Activity 10 is due as the Operation 0010 is assigned the the 1200 hour Cycle
Final Confirmation for the Maintenance Oder
TECO the MO

Option to create Measurement Document (Counter Reading reported by Technician at time of Preventive Maint.work)
The Technician reported new Counter Reading at 1250 hours at time of Preventive Maintenance
(was 1210 previously)

New Due is Package for the
1200 hour and 2400 hour with 2 Operations
Enter Reading#4
at 2440 hours to simulate next Package Due for both 1200h and 2400h (result in 2 Operations in the MO)
Reading#3 was 1250
Reading#4 is 2440
