* A work package now has three scheduling modes:

* Manual

* Start as soon as possible

* Start no earlier than

End of the insertion Begin of the deletion packages module and the Gantt module there are two new work package columns:

* Scheduling mode

* Constraint date


End of the deletion ##### **Date picker:**

* The date picker will be Primerised.

* _Changes to the info/warning banner are described in a separate section below._

* There is now an _UnderlineNav_ bar at the top:

* With three options:

* Dates (the standard date picker)

* Predecessors

* Successors

* _The Predecessor and Successor tabs are described in a separate section below._

* The "Working days only" check box is shorted to "Working days".

* There is a new dropdown with label "Scheduling mode" with the three options.

* **Manual scheduling:**

* Additional fields:

* None

* Date selection:

* The dates are freely selectable, without restrictions.

* Relations don't affect the start and finish dates.

* A manually scheduled work package can push and pull successors.

* **Start as soon as possible:**

* Additional fields:

* None.

* Date selection:

* The _Start date_ and _Finish date_ fields are read-only

* Duration remains editable

* The mini calendar goes into read-only mode Begin of the insertion


End of the insertion Begin of the deletion

* **Start not earlier than:**

* Additional fields:

* Constraint date:

* This will be in a different colour.

* The constraint date will be marked in the same colour in the date picker, with top, left and bottom borders (but no right border, to suggest that the constraint is only on one side)

* Date selection:

* In most cases, start date will be the same as the constraint date.

* Changing the _start date_ will change the _constraint date_ to that same same date, regardless of if the new start date is before or after the current constraint date.

* If there is a predecessor, it can move a work package into the future (past the constraint date) but never earlier than the constraint date.

* If constraint date is _before_ current start date, it can be changed independently without affecting the start date.

* If constraint date is _after_ the current start date, the start date will be changed to the constraint


End of the deletion ##### **Date picker banners:**

* **Manual scheduling:**

* Colour: Warning.

* Text:

* **Manually scheduled. Relations will not affect dates.**

Change scheduling mode for automatic scheduling.

* Action: Show relations

* **Start as soon as possible:**

* Case 1: The work package does not have a predecessor, the start date is the same as the project start date.

* Colour: Info

* Text:

* \*\*Dates are automatically set by the project start date.\*\*

You can modify this in your project timeline.

* Action: Project timeline

* Case 2: The work package has a predecessor.

* Colour: Info

* Text:

* \*\*Start date is set by a predecessor.\*\*

Changes to a predecessor may move this work package.

* Action: Show relations Begin of the deletion

* **Start not earlier than**

* Case 1: The start date is not the same as the constraint date because a predecessor has pushed it tgo the future.

* Colour: Info

* Text:

* \*\*Start date is set by a predecessor.\*\*

Changes to a predecessor may move this work package.

* Action: Show relations

* Case 2: The start date is the same as the constraint date.

* Colour: Info

* Text:

* \*\*Start date is limited by a constraint date.\*\*

Predecessors can only move this work package after this date.

* _To be defined_


#### Out of scope

* The ability to change the default schedule mode.

* At an admin or a project level

* Other scheduling modes such as "Must start on" or "Start not later Begin of the insertionthan", "Start no ealier than".End of the insertion Begin of the deletion than"End of the deletion

* Editable lag in relations.

* This will have been addresssed by the time we work on this feature: ###22360
