How to manage unmet demands in Supply Planning (planned order not created for sales order lines)

Hi,

We have some sales order lines for which we do not have any planned order created to supply them.

When looking at the Unmet Demand measure, we can see that it is filled. However, we don't understand what to do with this information.

The suggested due date for those is still within the horizon of the plan.

There is no exception raised for this item/sales order.

The late demand analysis does not show any data for it, so cannot expedite anything from here.

Number of days to calculate pegging is not filled.

We use a constrained plan by lead times only, we haven't set any capacity constraints.
