NetSuite MRP - Work Orders Scheduling Way Too Early Getting planned work orders scheduled months before demand. Example: • Planned WO: 10/9/2025 (today) • Pegging shows demand: 4/10/2026 (6 months away) Happening across all items. Transfer orders calculate correctly with proper dates, only work orders are wrong. Setup: Multi-location supply chain, 1-day transfer lead times, 0 lead time on assemblies. Anyone seen this? What causes MRP to ignore demand dates and schedule WOs immediately?'

There are a lot of datapoints that could be doing this, can you screenshot the location level supply planning fields ?

yes so for some context to why we are setting some of the values we're setting: our production structure is outsourced, the way we capture cost of production is a PO for the WIP item (inventory item for cost of production that gets used on FG build). I was having some issues because i need MRP to make my WO available in full on end date as opposed to how it was calculating: making inventory available starting on the WO start date. To mitigate this i have no lead time on my assembly items, and i instead set it on the WIP items. This way MRP reads my FG inventory as available on the date it is completed, and i know to place the PO for the WIP item using the lead time. this PO <> WO timing is correct, the Storage > Fulfillment location transfer timing is correct. The only thing that is showing up wrong is the end date of the FG WO. with that context in mind i am setting location sublist fields via script using some settings i have on a configuration record for item collections. • WIP is getting lead time in manufacturing location • FG is getting MOQ in manufacturing location and safety stock in Fulfillment/Storage locations • both types are getting: ◦ past due forecast days = 1 ◦ late days period = 1 ◦ backwards/forwards consumption days = 14 ◦ demand time fence,planning time fence = null

What does your purchase pegging for the WIP item look like?

correct we are not using outsourced manufacturing. when i inherited this account we were set up this way and i tried to move us to it, but there were some internal reasons to keep the current structure. on correction we are only using WIP as the cost to manufacture, the actual raw ingredients are used on the revision as expected. pegging on the WIP is looking weird actually. i don't remember it looking like this earlier. now i see that my actual WIP PO is pegged to the planned WO and the planned WIP PO is pegged to my actual WO. are things getting thrown off because the actual PO/WO are needed for transfers that are due before they're set to be completed?

What about planning time fence? I think that will suppress signals if you are within that fence.

but outsources manufacturing won't solve the issue of the uncovered demand between 10/10 - 10/17 right? it will only fix the pegging issue right? which i would like to fix, but i'm more concerned about the timing of the planned order. my real WO and PO both have a 10/18 end date so those are aligned, the issue is that before 10/18 it wants me to squeeze in a new WO because i don't have any supply on the assembly to get the planned transfers before 10/18. so the mismatch of the planned PO to the real WO is just due to the timing of the planned WO. how do we get MRP to ignore that the next week we will not be able to supply the demand and just accept the lateness and use the real WO instead?

I mean, you won't see any planned work orders less than 2 weeks out. It should try to aggregate at the 15th day out any supply signals that fell within that window.
