Set Maintenance Order to Under Preparation

Explanation

This activity is used to set a maintenance order to the Under Preparation status. This is done when all the tasks which the planner wants included in the maintenance order scope are assigned. When a maintenance order is in the Under Preparations status, it is possible to:

• Specify instructions for tasks without connected operations.
• Add additional operations to a predefined list or cancel operations that are no longer valid.
• Add additional tasks to the maintenance order.
• Change the grouping ID in order to remove the current execution logic structure (ELS) and create a new ELS based on new grouping criteria.
• Connect document references to operations.

Prerequisites

To perform this activity, a maintenance order in the Initial Scope Definition status must exist.

System Effects

• Operations (instructions and subtasks) will be connected to all assigned tasks with the Work Order and Execution Logic Structure distribution types.
• If operations are connected to the assigned tasks, the tasks will be set to the Under Preparation status. If predefined operations do not exist for any assigned tasks, these tasks will be set to the Incomplete status.
• For a maintenance order with the Execution Logic Structure distribution type, an execution logic structure (ELS) will be created automatically based on the ELS template defined for the given grouping ID. The following effects will occur for the generated ELS:
  • The planned start date for all the execution logic orders (ELOs) will be set to the date given in the Req Start field on the maintenance order. This is valid for both grouped and ungrouped operations.
  • The dependencies predefined in the ELS template will be drawn between the relevant ELOs.
  • The grouping and ELO nodes in the ELS will be sorted in the same order as set up on the ELS template. This sequence is reflected in the ELS navigator and the Gantt chart available in the Exec. Logic tab. Ungrouped ELO nodes will always be placed at the bottom of the ELS navigator and the Gantt chart.
  • The duration of the ELO is set to the hour consumption of the operation with the highest consumption within the ELO.
  • The planned finish date for the ELO will be calculated by adding the duration of the ELO to the planned start date.
