Enter Maintenance Plan
Explanation
This activity is used to create a maintenance plan for preventive maintenance
activities, represented by maintenance codes, which need to be scheduled on a
specific frequency against a serial part. The maintenance plan provides
capability to define the frequency and recurrence of maintenance activities. The
interval for the activities could either be based on a single operational
parameter, a calendar interval, a combination of an operational parameter and a
calendar interval, or a combination of an operational parameter along with other
applicable operational parameters and/or a calendar interval.
For every maintenance code in the plan, an appropriate calculation rule needs
to be set. Normally, one of the maintenance codes will have the Overhaul
calculation rule.
You cannot delete a maintenance code if it is connected to maintenance
actions for the serial parts. For more information about the rules when
registering maintenance plans, refer the online help file
Interval Based Maintenance Program.
Prerequisites
- A maintenance program must exist.
- Serial parts must be defined for the maintenance
program.
- Maintenance groups must be defined for the serial parts associated with
the maintenance program.
- Maintenance codes must be defined as basic data in
the Maintenance Program Basic
Data/Maint Code tab.
System Effects
- A maintenance plan is defined for a given maintenance program, serial
part, and maintenance group.
- The maintenance codes entered on the maintenance plan are automatically
created as valid maintenance codes for all revisions of the serial part and
can be connected to task cards. For more information, refer the online help
file

Procedure
Select from the following options to create a maintenance plan for a
maintenance program:
Option 01:
- Open the Maintenance Plan window and query (F3) for the
necessary maintenance program, part revision and maintenance group for which
you want to create a maintenance plan.
- To create an interval for a primary releasing operational parameter for
the maintenance plan, create a new record (F5) in the upper table of the
Intervals tab.
- Enter the preferred maintenance code for the maintenance plan in the Maint Code field. Use the List of Values to select a value.
- To define phased inspections, a value must be entered in the
Preceding Maint Code field. In this field, enter the maintenance code to
be executed preceding the maintenance code defined in the Maint Code
field. The Preceding Maint Code must be a maintenance code already
present in the same plan and have calculation rule Phased Inspection.
A suitable value can be selected from the drop-down list or from the List of
Values.
- Select the Phased Inspection Start check box if the maintenance
code is the starting point of a sequence or cycle of phased inspections.
- Enter the preferred maintenance interval for the maintenance plan in the
Maint Interval field.
- Select the Recurring Calculation check box if the maintenance
code is to be calculated at recurring intervals. Specify the Recurring
Interval and/or the Recurring Cal. Interval. Note that the Recurring Cal. Unit
is required when a recurring calendar interval is
specified.
- Select the Use Tolerance check box if tolerances are to be used
for the given maintenance code. Specify the Lower Tolerance and the
Upper Tolerance limits. If necessary, select the Adjust Above +
Tolerance check box as well.
- To enable adjustment of calendar based intervals, select the Cal. Int. - Adjust if done Early
check box and the Cal.
Int. - Adjust if done Late check box.
- When the Cal. Int. - Adjust if done
Early check box is selected, the next due date will always follow the due date of the
previous execution whenever the maintenance has been performed too early.
- When the Cal. Int. - Adjust if done Late check box is selected, the
next due date will always follow the due date of the previous execution
whenever the maintenance has been performed too late.
- Note that the settings for Cal. Int.
- Adjust if done Early and Cal. Int. - Adjust if done Late does
not have any effect if the Based on Performed Date has been specified.
- In the Days Forewarning field, specify the number of dates before
the maintenance code's due date that the maintenance action is to become
available for planning.
- In the Duration Workshop field, specify the number of days the
equipment is expected to be in the workshop.
- In the Duration Unit field, specify the unit of
measurement for the duration in the workshop.
- In the Calculation Rule field, specify the calculation rule for
the given maintenance code. The calculation rule Inspection is
selected by default.
- In the Cycle field, indicate whether the execution of maintenance
actions for the maintenance code will trigger a zero setting of accumulators
in the operational record. Note: For parts that are not overhauled
the value must always be No Cycle.
- In the Mx Event Remark field, enter any additional
information on the interval maintenance. Entering a value in this field is
optional. Double-clicking on the field will open
a text editor where you can enter text in a more convenient fashion. When an
event is created for the
interval maintenance, this information will be transferred to the Mx
Event Remark field of the corresponding event record on the maintenance order.
- In the Post Maint Check ID field and the Post Maint Check
Revision field, enter the identifier and revision of the post
maintenance check that is to be carried out after the interval maintenance
event has been
finished. Use the List of Values to select suitable values.
- Save the record (F12).
- To create an interval for a secondary releasing operational parameter
for the maintenance plan, create a new record (F5) in the lower table of the
Intervals tab.
- In the Operational Parameter field, enter the secondary releasing
operational parameter. Use the List of Values to select a valid value.
- In the Maint Interval field, enter the required maintenance
interval.
- Save the record (F12).
Option 02:
- Open the
Define Maintenance Program window and query (F3)
for the necessary maintenance program.
- Right-click and click Maintenance Plan. The
Maintenance Plan window is opened with all serial parts and maintenance groups
that are connected to the maintenance program and for which you want to
create maintenance plans.
- To create an interval for a primary and/or secondary releasing
operational parameter for the maintenance plan, continue with steps 2 - 21
detailed in Option 01.
Option 03:
- Open the
Define Maintenance Program
window and query (F3)
for the necessary maintenance program.
- Click the
Maintenance Groups tab.
- Select the row containing the part number you want, right-click and then
click Maintenance Plan. The
Maintenance Plan window is
opened with the serial part, maintenance group and maintenance program for
which you want to create a maintenance plan.
- To create an interval for a primary and/or secondary releasing
operational parameter for the maintenance plan, continue with steps 2 - 21
detailed in Option 01.
