1. If your service appointments have custom fields, make sure to give the fields read and edit access. See [Appointment Bundling Limitations](https://help.salesforce.com/s/articleView?id=service.fs_set_up_bundling_limitations.htm&release=264.0.0&type=5 "Review the limitations of Appointment Bundling.").
2. Open an appointment bundle aggregation policy that has Aggregation Action defined as Set downscaled duration.
3. In the Appointment Bundle Aggregation Policy, go to the Related tab.
4. In the Appointment Bundle Aggregation Duration Downscales panel, click **New**.
5. Give the policy a unique name.
6. For From Bundle Member Number, enter the first bundle member’s number that the downscale applies to.
7. For To Bundle Member Number, enter the last bundle member’s number that the downscale applies to. To always downscale to the last bundle member, leave this field empty.
8. Enter the percentage of reduction.
9. For Max Reduction, enter the maximum reduction for a bundle member service appointment, in minutes.
10. Save your changes.

Example

A printer maintenance company must fix multiple printers in the same office building. For the first service appointment, the mobile worker needs time for parking, passing the building’s security clearance, organizing the tools, and then fixing the printer. But when the mobile worker gets to the second service appointment, they can go straight to fixing the printer. In this scenario, to get a better estimate of the bundle’s duration, configure the downscaling to start from the second bundle member.

Note If you define aggregation duration downscales where the service appointments overlap and include Max Reduction values, it can lead to inaccurate results. See [Appointment Bundling Limitations](https://help.salesforce.com/s/articleView?id=service.fs_set_up_bundling_limitations.htm&release=264.0.0&type=5 "Review the limitations of Appointment Bundling.").
