The system displays the following fields:

Last WO Generated	The last work order that has been generated for carrying out preventive maintenance.
Last WO Sch. Start Date	The date on which the last preventive maintenance work order was scheduled to start.
Last WO Compl. Date	The date on which the last preventive maintenance work order was scheduled to complete.

Enter the following fields in the “Usage Based" multiline if you wish to define schedules based on the usage of the equipment or location:

Parameter	The parameter based on which the preventive maintenance must be done on the equipment or location (Alphanumeric, 30). This field cannot be modified. If you are to enter a new parameter, ensure the following:
	The parameter is already defined as a consumption parameter in the “Create Parameter” activity of the “Equipment Induction” business component and is in the “Active” status.
	The parameter has already been attached to the equipment or the location in the “Create Equipment” or “Create Location” activities.
	Help facility available

Note: Ensure that the parameter is unique to the multiline.

Interval

The value of the parameter after which preventive maintenance must be carried out (Decimal). This field should not be left blank if a parameter has been specified in the “Parameter” field. Ensure that the interval is a positive number.

The system displays the following fields in the multiline:

Interval Unit	The unit of measurement of the parameter.
Next Due Value	The value of the parameter at which the next preventive maintenance on the equipment is due.

Enter the following fields in the multiline:

Extended Value	The value of the parameter at which you wish to carry out the preventive maintenance on the equipment or location (Decimal). Ensure the following when you enter the value in this field:
	The value entered here is a positive number.
	The value entered here is more than the present value of the parameter.
Adjust Next Due Value?	Use the drop-down list box to specify whether you wish to adjust the next due parameter values on which preventive maintenance must be carried out based on the value entered in the “Extended Value” field. The system provides the options: “Yes” or “No”. Do not leave this field blank, if you have specified a value in the “Extended Value” field in the multiline.

The system displays the following fields in the multiline:

Last WO No.	The number of the last work order that was raised for carrying out the preventive maintenance.
Value At Last WO	The parameter value at which the last work order was raised for carrying out the preventive maintenance on the equipment/location.
Date Of Last WO	The date on which the last work order was raised on the equipment/location.
Value at Last Meter Reset	The value of the parameter as on the date of the last meter reset that was done.

Click on any one of the following options in the “Execution Option” group box:

Calendar and Usage Sch. Independently	Click this button if you wish to generate preventive maintenance work orders for the calendar-based schedule and for every parameter in the usage-based schedule.
Calendar OR Usage Sch. whichever earlier	Click this button if you wish to generate a preventive maintenance work order for the earliest of the calendar-based or the usage-based schedule.
Calendar and whichever earlier in Usage	Click this option if you wish to generate preventive maintenance work orders for the calendar-based schedule and for the earliest of the parameters in the usage-based schedule.

Check the box in the “Select” column of the multiline to select the parameter for which you do not wish to define interval schedules.
Click the “Edit” pushbutton to create interval-based schedules.

The system saves the details of the interval schedules.

The system displays the following fields in the “Record Statistics” group box:

Created By	The login ID of the user who created the preventive maintenance schedule.
Created Date	The date and time at which the preventive maintenance schedule is created.
Last Modified By	The login ID of the user who last modified the preventive maintenance schedule.
Last Modified Date	The date and time at which the preventive maintenance was last modified.

Editing interval schedules – An overview

This page allows you to edit the details of the interval schedules that are already defined.

If you have defined a calendar-based schedule, you can modify the time interval after which the preventive maintenance is due to be performed, the unit of the time interval and the type of the interval.

If you are unable to start the work on the preventive maintenance on the next due date, you can specify the extended date on which you wish to start the preventive maintenance. You are also given the option of adjusting the new due date based on the extended date. This can be explained with the help of the following example:

Suppose preventive maintenance is due to be performed on April 1 and an interval of one week is provided for carrying out the next preventive maintenance. If you have entered an extended date of April 3 and have set the option of adjusting the next due date as “Yes”, the system recalculates the next due dates as April 3, April 10, April 17and so on. If you have set the option of adjusting the next due date as “No”, the system arrives at the next due dates as April 3, April 8, April 15and so on.

If you have defined a usage-based schedule, you can re-define the parameters based on which the preventive maintenance must be done and the value of the parameter after which the preventive maintenance must be done. If you are not able to perform the preventive maintenance on the specified parameter value, you can enter the extended value based on which the maintenance can be performed. You can also specify whether the subsequent parameter values must be adjusted or not based on the extended parameter value.

The system displays the details of the last work order that has been carried out based on the preventive maintenance along with the date on which it was performed. For a usage-based parameter, the system displays the value of the parameter as on the date of the last meter reset.
