Prepare and Plan WO for Execution Logic Structure—Exercises

Main Exercise

Purpose: The purpose of this lesson is to show you how to sort and order the work orders in a work order structure that was created for an Execution Logic Structure (ELS). The work order structure for an ELS is created when a maintenance order with the Execution Logic Structure distribution type is released. It is a structure of work orders containing operations based on predefined grouping criteria. The grouping criteria is defined per product and model, selected on a maintenance order and functions as a template when generating the work scope for the maintenance order.

In this lesson you will learn how to,

                - Change the start and end dates for a work order and/or an operation

                - Move operations between work orders

                - Use the different options for defining dependencies between the operations of a work order

                - Use the different options for defining dependencies between the work orders in the work order structure

                - Sort duplicate operations for one or more work order, automatically or manually

                - Remove Master/Slave definitions from one or more work orders

                - Calculate and view the critical path

                - Cancel an operation on a work order, including the steps for cancelling a master operation

Once you have finished updating the ELS work order structure (e.g., sequencing, defining dependencies and sorting duplicates), you can continue with the normal work flow for processing work orders. For instance, you can start with the Prepare and Plan WO exercise. To conclude the work order, refer the WO Concluding exercise.

Prerequisites: In order to perform the exercises in this lesson, the Releasing a Maintenance Order exercise must have been completed.
