# Planning date

The **Planning Date** on the project planning line is the starting point for the material planning calculation in Microsoft Dynamics 365 Business Central. The **Planning Date** is initially set by the project task starting date. In that way, material required for the project task is available when the project task starts.

When ordering material for the project task, the **Planning Date** is copied to the supply order:

- **Purchase Order Line**: **Planned Receipt Date**
- **Production Order**: **Due Date**
- **Assembly Order**: **Due Date**
- **Transfer Order**: **Receipt Date**

The Microsoft Dynamics 365 Business Central planning system then calculates the action messages based on the item settings such as lead time and capacities.

## Steps - Change planning date

1. When a project task starting date changes, the project planning lines linked to that project task and **not transferred** to a supply order change accordingly.
2. When a project task starting date changes, the project planning lines linked to that project task and **transferred** to a supply order are highlighted as **Ambiguous**.
3. The **Sync Demand-Supply** action assists the planner in implementing the date changes for each line:
  - This assumes that contact with the vendor, production department, and assembly department is required to confirm the date change is possible.
  - The action prompts the planner to enter the new planning date for the project planning line. When a date is selected, a new prompt shows the new planned receipt date or due date. When confirmed, the action makes the changes in the correct sequence and updates the dates in the reservation entries.
  - You can select several project planning lines provided they have the same replenishment order.
  - When successfully completed, the lines are no longer highlighted as **Ambiguous**.
