Demand & Supply

Demand and supply records are the raw material of MRP. Every shortage, suggestion, and projected-availability number in Supply-Demand Intelligence is derived by netting these two streams. This page explains what they are, how to browse them, and the fields that matter.

For how they net into shortages, see Supply-Demand Intelligence (Overview).

Where to Access

• Demand List — /sdi/demands (or click any source on the SDI Dashboard → Demand Sources card).

Demand

Demand is anything that will consume inventory.

Demand types

• Sales Order — a customer order awaiting fulfillment.
• Work Order Component / Build Component — components required to manufacture or assemble a parent item (the two are grouped together in filters as "Work Order / Build Component").
• Forecast — expected future demand you entered or generated (see Forecasting).
• Transfer Out — inventory committed to move to another location.
• Safety Stock — a minimum buffer the system treats as standing demand.

Demand record fields

• Item and Location
• Type — color-coded badge (see above)
• Qty Required — total quantity demanded
• Qty Open — quantity still unfilled
• Date Required — when it's needed
• Priority — lower number = higher priority (≤10 shows red, ≤20 orange)
• Status — see below

Demand status

• Open — not yet fulfilled
• Partially Filled — some quantity covered
• Filled — fully covered
• Cancelled — no longer active

Browsing demand

The Demand List supports filters for Item, Location, Type, and Status, with a Clear Filters button. Selecting the Work Order / Build Component type shows both work-order and build component demand together.

Supply

Supply is anything that will replenish inventory.

Supply types

• On Hand — current physical stock.
• Purchase Order — quantities on order from vendors.
• Work Order / Build — quantities being produced in-house (grouped as "Work Order / Build" in filters).
• Transfer In — inventory inbound from another location.
• Planned Order — a system-proposed replenishment not yet firmed.

Supply record fields

• Type, Qty Ordered, Date Expected, and Status.

Supply status

• Open — expected, nothing received yet
• Partially Received — some quantity received
• Received — fully received
• Cancelled — no longer expected

Demand and supply for any single item are shown side by side in the Planning View, which is the best place to inspect them in time-phased detail.

Pegging — linking supply to demand

Pegging records which supply is earmarked for which demand, so you can trace exactly what a given purchase or work order is covering. Pegs come in three firmness levels:

• Firm — a committed link between a specific supply and demand.
• Planned — a link to a planned (not yet firmed) order.
• Suggested — a system-proposed link awaiting acceptance.

When you resolve a shortage from a sales-order line (for example via the Multi-PO Creator), the new purchase line is linked back to that demand so the relationship is preserved end-to-end.

Tips

• Use Priority on demand to influence which orders get covered first when supply is tight.
• If an item shows demand you don't expect, filter the Demand List by that item to see every contributing source (a forecast, a transfer, or a parent build).
• Watch Qty Open rather than Qty Required — open quantity is what still needs covering.
