For subcontracting, we need to consider both vendor lead time and
manufacturing lead time, and DTPMO (Days To Prepare MO) on the BOM.
Subcontracting delay =
max(Vendor lead time, Manufacturing lead time + DTPMO) + Days to Purchase + Purchase security lead time
Same thing applied to Bom overview, except:
1. Availability state will be computed based on the delay time of it's
components. DTPMO on the bom won't be take into account.
2. Lead time will use the DTPMO on the BOM. DTPMO will be added to
the lead time when it's a manufacturing bom or when it's a
subcontracting bom with Manufacturing Lead Time + DTPMO > Vendor Lead Time
