This activity is used to sequence an execution logic structure (ELS). You can start sequencing and add or remove dependencies to the execution logic orders (ELOs) and task cards of an ELS once it is generated. You can use the Predecessors and Successors dialog to add predecessor and successor relationships to a task card in the structure. It is also possible to move an ungrouped task card into an ELO node. This functionality is described in detail in the activity Move Task Card within Execution Logic Structure.
Once you have finished sequencing the ELS, you need to run the Plan Execution Logic Structure option from the Execution Logic Structure Gantt page to get the ELOs and task cards placed correctly in time. If the planned dates are outside the required date interval, the Change Required Dates on the Maintenance Order dialog will open, and you can enter the earliest start and latest finish dates there. If you wish to reset the entire ELS back to how it was default generated but based on the changed, earliest start and latest finish dates, enable the Reset the Execution Logic option from the dialog.
