Checking start and end date-times of activity definitions after compiling
You can view the influence of an activity type on automatically populated fields by Planon ProCenter after a maintenance plan is compiled. The following criteria are applied to determine the values with which these fields are populated. For example: the start and end date-times of standard activity definitions and asset activity definitions, once they are transferred to a compiled maintenance plan.
Activity type of asset activity definition or standard activity definition
Available start & end date-times of asset activity definition or standard activity definition before compiling
Results in the following start & end date-times of activity definitions after compiling
Other than Replacement
If no start date-time is specified in either the relevant asset activity definition or standard activity definition, and no value is specified in the Maintenance start date field of a linked asset /building element:
The start date of the activity definition is set to be the same as the start date of the maintenance plan.
Other than Replacement
If start date-times are specified in both the Maintenance start date field of the linked asset (or building element) and in the asset activity definition / standard activity definition:
The latest start date-time of the two is set to be the start date-time in the compiled maintenance plan.
Other than Replacement
If end date-times are specified in both the Maintenance end date field of the linked asset (or building element) and in the asset activity definition / standard activity definition:
The earliest end date-time of the two is set to be the end date-time in the compiled maintenance plan.
Activity type of asset activity definition or standard activity definition
Available date-times of linked asset before compiling:
Results in the following start & end date-times of activity definitions after compiling
Replacement
In FieldDefiner, if the business object setting Set expected technical end date of asset as start date of activity definition is set to Yes; or if the Expected economic end date is unspecified:
The Expected technical end date of the linked asset (or building element) is set to be the start date-time in the compiled maintenance plan.
Replacement
In FieldDefiner, if the business object setting Set Expected technical end date of asset as start date of activity definition is set to No; or if the Expected technical end date is unspecified:
The Expected economic end date of the linked asset (or building element) is set to be the start date-time in the compiled maintenance plan.
Replacement
If no Expected economic end date or Expected technical end date is available:
The start date of the activity definition is the sum of the value in the Date first used field of the asset (or building element) and the Frequency specified in the schedule of the asset activity definition / standard activity definition.
Replacement
If no Date first used is available for the linked asset (or building element):
The start date of the activity definition is the sum of the value in the Date of manufacture / construction field of the asset (or building element) and the Frequency specified in the schedule of the asset activity definition / standard activity definition.
Replacement
If no Date of manufacture / construction is available for the linked asset (or building element):
The start date of the activity definition is the sum of the value in the Maintenance start date field of the asset (or building element) and the Frequency specified in the schedule of the asset activity definition / standard activity definition.
Replacement
If date-times are available in one of the above-mentioned fields of the linked asset (or building element):
- Expected technical end date
- Expected economic end date
- Date first used
- Date of manufacture / construction
and in the asset activity definition / standard activity definition:
The latest date-time of the two is set to be the start date-time of the activity definition in the compiled maintenance plan.
Replacement
If no date-times are available in one of the above-mentioned fields of the linked asset (or building element), nor in the asset activity definition / standard activity definition
or
if the above-mentioned dates are earlier than the start date of the maintenance plan:
The start date of the activity definition is set to be the same as the start date of the maintenance plan.

Example:
Airco Unit (with a maintenance start date of 1-4-2015)
Maintenance activity definition 1: three monthly service check
Maintenance activity definition 2: annual legal check
Suppress first activity field value = YES
This results in the following schedule: Maintenance activity definition 1: 1-7-2015, 1-10-2015, 1-1-2016 etc. Maintenance activity definition 2: 1-4-2016, 1-4-2017 etc. The first activity, scheduled on 1-4-2015 is skipped in both cases. Since this setting can be applied per maintenance activity definition, it is possible to deviate between maintenance activity definitions within a maintenance service plan.
