does anyone use this field "Work Order lead time" where is this field used? on demand planning? is this field really useful?

demand planning yes...very important, though, that this value is as the time in days to produce one unit; if you do not take this into consideration then it is very easy to end up with planned supply dates in May 2096 (may or may not be from personal experience)

how does it work? is it computed by NetSuite Demand Planning or you set it up like master data?

yes, for an assembly item you would see this field at the location level. May need to enable DRP to use it. Once displayed, the value calculated as Demand Qty * WO Lead time

Hey Daniel do you know if there is an option to not have it calculate by quantity? We do batch processing so for example I want the entire WO of an assembly to be 3 days. I don't care about the quantity as this is messing up our calculations. For example I want assembly A to have a lead time of 5 days, Assembly B which is a component of Assembly A has a lead time of 10 days. I want the total to be 15 days not 15*the quantity

There is not a setting or preference that would allow this, directly. I have been able to account for a similar scenario by increasing the purchase parts lead time proportionately or Firming the work order ahead of any supply planning runs.

Hi Daniel, sorry I feel like I am missing something as I'm not quite understanding how editing the purchase parts lead time would account for the work order end date being like three years in the past (quantity of 100 on my sales order)

hey @ZergiNate, so there are two scenarios: 1 - increasing parts lead time, and 2 - firmed work orders scenario 1: if you want your WO Lead Time to be 5 days for an assembly, and the parts total lead time is 10 days, you increase parts lead time to 15 days and set WO lead time of the Assembly to be 0 or null. consequence of this is that you are then going to require earlier raise/cut/release of Purchase Orders, and the Work Orders will look & report as if they start and end on the same day; but you can ensure that your parts would arrive in time to meet demand dates. scenario 2: This still involves not using the WO Lead Time field (leaving null), but a custom field with the value in days. But essentially let supply planning run, get WO's suggested/created and then following up with editing the WO Start/End Dates according to the custom field and checking the 'Firmed' box, then re-running supply plans so that further down (purchase/work) orders can update according to these firmed dates. Consequence here is more steps and having to run supply planning process multiple times.

Thank you Daniel this was very helpful, I am going to test the firming of the work orders. I assume I could firm them run everything again and then un firm once my whole process is complete
