Generate maintenance planning

Use the Generate Maintenance Plan (tsspc2200m000) session to generate maintenance planning. You can plan maintenance activity for the installation group and serialized item that the service organization manages. You can schedule and display the activities in the Planned Activities (tsspc2100m000) session. The maintenance planning provides the maintenance activities that must be carried out in the long term.

The operational planning of the maintenance activities is based on the service order planning. All the operational (service) activities are carried out by means of service orders.

  1. Service contract

    If any service contract is active for the Installation group, the planning is not generated for that Installation group.

  2. Serialized items

    Select all top serialized items that are active during the specified Date-From and Date-To period. If the Date-From is earlier than the start date of the top serialized item, the Date-From becomes the start date. If the end date of the top serialized item is later than the Date-To, the Date-To becomes the end date.

  3. Planned Activities

    The planned activities are generated for the serialized items that are valid between these two dates. LN also generates the planned activities for the child serialized items that are related to the top serialized item. The child serialized items must also be valid.

  4. Usage Class

    The usage class that you must use when planned activities are generated is selected in the following order:

    1. The usage class of the serialized item
    2. The usage class of the first parent serialized item
    3. The usage class of the Installation group
    4. The usage class
  5. Reference Activities

    LN checks if reference activities linked to the item are present. If present, the reference activities are used to generate the planned activities.

  6. Maintenance Cycle

    The maintenance planning can be carried out in three different ways, based on the start of the maintenance cycle:

    • Start Date of Serialized Item: The start date of the maintenance cycle is equal to the start date of the serialized item.
    • Time from in Selection Range: The maintenance cycle starts on the Date-From that the planned activities will be generated.
    • 1st of January: The maintenance cycle starts on the first of January.

The relative movements are transferred into the actual dates based on the value of the Maintenance Cycle field in the Items - Service (tsmdm2100m000) session. After receiving the start date, the first workable date receives the actual planned start date. The activity duration is added to this date to determine the end date.

To find the first workable date and plan forward, the search path for calendars is:

  • The calendar of the serialized item.
  • The calendar of the service department that is linked to the Installation group.

Earliest start time = ((Planned start time + Planned end time)/2)- (Tolerane period x 0.5)

For each planned activity that is generated, the requirement lines are copied from the Resource Requirements (tsacm2120m000) session to one of the following sessions:

  • Planned Activity - Material Requirements (tsspc2110m000)
  • Planned Activity - Labor Requirements (tsspc2111m000)
  • Planned Activity - Other Requirements (tsspc2112m000)

Process Report: List of planned activities generated.

Error Report: List of errors.

Defaults:

  • The Date From is the current date.
  • The Date To is the current date + one year.
