| # To generate maintenance planning Use the Generate Maintenance Plan (tsspc2200m000) session to generate maintenance planning. You can plan maintenance activity for the cluster and serialized item that the service organization manages. You can schedule and display the activities in the Planned Activities - Cluster (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. The maintenance concepts are copied to the planned activities. How to generate maintenance planning Step 1. Service contract If any service contract is active for the cluster, the planning is not generated for that cluster. Step 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. Step 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. Step 4. Usage Class The usage class that you must use when planned activities are generated is selected in the following order: The usage class of the serialized item The usage class of the first parent serialized item The usage class of the cluster The usage class Step 5. Predicted Activities LN first checks whether predicted activity are present for the item of the serialized item in the Maintenance Concept - Predicted Activities (tsspc1125m000) session. If present, the child serialized items of this serialized item are no longer traversed and the predictions are copied to planned activities. Step 6. Reference Activities If no predicted activities are present, LN checks if reference activities linked to the item in the Maintenance Concepts - Item (tsspc1120m000) session are present. If present, the reference activities are used to generate the planned activities. Step 7. 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. If the activity is derived from a prediction, and the prediction has the child item specified, the corresponding serialized item is found by traversing the tree below it. If more than one serialized item derived from the same item is found, the prediction is ignored. 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 cluster. Earliest start time =
For each planned activity that is generated, the requirement lines are copied from the Reference Activity - 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. |
