Modifications made to projects, project tasks, and time entries can affect sales order invoice schedules if the project is assigned a billing schedule type. When such changes are entered, they trigger a project plan recalculation, as well as an invoice schedule recalculation.
For example, you may have a weekly billing schedule associated with a sales order for a project with a duration of 2 weeks. The invoice schedule lists two expected bill dates. If a project task record is changed in a way that the project duration becomes 4 weeks, then the invoice schedule on the sales order is also updated. The updated schedule will include four expected bill dates.Note:
The following changes do not trigger project plan or invoice schedule recalculation:
Changes made to work calendars
Changes made to billing schedules
