The Synchronize to activity definitions action allows you to update all activity definitions linked to a selected standard activity definition. When you select the action, the system synchronizes Activity costs, Planning details, and/or Checklist items and brings each activity definition in line with the setup defined in the standard activity definition.

For more information on synchronizing Activity costs, Planning details, and/or Checklist items, see Synchronizing activity costs, planning details and checklist items to activity definitions.
