Expedite Days Calculation

Summary

expedite days are minor to lead time at the plan start

Hi, 

Does anyone know in what cases the expedite days are minor to lead time at the plan start?

We have an order that needs to be covered at the plan start, the Lead Time is 145 days but the expedite days are only of 103 days, in theory, this two fields must have the same value.

We have only one calendar (24/7) for supplier and organization.

I uploaded a pic with evidence of this.

Thanks.
