What is the best wat to ensure ordering materials with a lead time will update as the schedule changes.

For example, task setting trusses needs a relationship with ordering trusses with a lead time of 4 weeks. the ordering task needs to adjust when the schedule changes.

    Hi stacie,

    Welcome to the Microsoft Q&A forum.

    Based on your description, you would like the Order Trusses task to automatically update whenever the Set Trusses date changes.

    You can configure it as shown below:

    • In the Predecessors field, enter: 1SS-4wks
    • Then select both tasks and click Auto Schedule. User's image

    The formula 1SS-4wks means:

    • 1SS: The ID of the Set Trusses task (this value may vary depending on your project file).
    • -4wks: Automatically schedules the task 4 weeks earlier than the linked task.

    Below is the result after applying this configuration.
