M3 order types and discount models to D365 sales and purchase: redesign, not translation
How M3's configurable order types (behaviour bundles in OIS010/OIS100), the six-tier discount model, and rebate agreements map to D365 F&O's fixed order lifecycle, trade agreements, and price/discount journals — and why this domain requires redesign, not translation.

Introduction
M3's order management model centres on the order type — a configurable behaviour bundle maintained in OIS010 (for customer orders) and the purchase order equivalent. An order type is not just a label;
M3 order types as behaviour bundles
Every M3 customer order in OIS100 carries an order type from OIS010. The order type determines:
Pricing, discounts, and the six-tier model
M3 evaluates pricing and discounts through a tiered cascade. The price base for an order line comes from the item's sales price on the M3 price list; discounts are then applied in layers, each identified by a discount number (Discount 1 through Discount 6). Each discount tier can be configured to apply by:
Customer and supplier masters
The M3 customer master holds: name and address, customer group, payment terms, currency, credit limit, delivery terms, tax category, and the statistical classification codes used in financial dimension defaulting.
Charges and landed cost
M3 supports charges at order header and line level: freight, surcharges, packaging, and handling fees. These are configured as charge codes and applied automatically by customer group, item group, or delivery mode, or entered manually on the order.
Knowledge check
Summary
M3's order type model bundles many behaviours into configurable codes; D365 distributes the same behaviours across multiple configuration areas. The trade domain requires systematic decomposition of every active order type, not a code-for-code translation.
