What Happens When the Planned Task Dates of Either of the Plans are updated Using FBDI or the REST API?

When you update the planned task dates through FBDI or the REST API for either the financial or the work plan, the dates automatically reflect in both the plans.

Note: The dates are updated only if you've selected the Define Common Financial Task Dates Across Work and Financial Planning check box.

The first time you open the work plan, you get a prompt to Select Update to apply constraints. The constraints preserve the start date for automatic tasks without dependencies created from FBDI or the REST API.

For a fixed-effort task, when task dates are updated from any other source other than Manage Project Plan page, on subsequent rescheduling, dates are preserved and resource allocations are recalculated.
