You can create work orders with scheduling dependency relationships (including child sibling work orders). For example, one work order's scheduled start date is dependent on another work order's completion. With this relationship, the next work order cannot start until the prior work order is completed. Note that to create an end to start dependency between two work orders, they should be siblings sharing a common parent.
To create End to Start dependencies:
Navigate to the Work Orders page (Maintenance Super User >Work Orders).
Query a work order. (See: Viewing Work Orders).
Click the work order and select the Work Relationships sub-tab.
Select a work order and in the Select Work Order field, and choose the option to Update Dependencies.
In the Work Order Dependencies page, click the Add Dependencies button.
Select a work order in the Dependent Work Order field. In the Dependency Type field, select Prior or Next.
Click the Apply button.
