MTO 202 ยท OBJECT MODEL
How does transfer of requirements create customer-specific supply?
In Make to Order, the sales-order item is not merely a commercial request. Transfer of requirements turns its schedule-line demand into an individual planning requirement that MRP can cover with customer-specific supply.
THE DEFINING CONTROL
Transfer of requirements is the planning bridge from sales order to supply
Item category, schedule-line category, strategy group, requirements type, and requirements class determine whether and how demand transfers. TOR sends the requirement to planning; ATP checks supply and determines the confirmation. They may act on the same schedule line, but they answer different questions.
CONTROL LAYERS
One customer request, four connected layers
Trace the customer reference from commercial control through planning, execution, stock, and financial close.
Item and schedule line
Material, configuration, quantity, requested date, item category, and schedule-line category establish commercial and logistical behavior.
Type, class, and TOR
Strategy and requirements determination select a requirements type/class whose controls govern transfer, account assignment, availability, and costing behavior.
Pegged demand and supply
The sales-order item becomes an individual requirement. MRP creates planned orders or procurement proposals retaining the customer reference.
Order-specific output
Execution produces or procures the required output; where the strategy uses sales-order stock, receipt remains assigned until delivery, billing, and margin completion.
SYSTEM BEHAVIOR
How TOR carries customer demand into execution
The customer reference should remain explainable across every generated object.
Create the sales requirement
The item and schedule line record configuration, quantity, requested date, and control categories.
Create individual demand
Requirements determination and TOR expose customer-specific demand to MRP in the individual planning segment.
Create assigned supply
MRP explodes the relevant BOM and creates planned, production, purchase, or subcontracting supply tied to the sales-order item.
Deliver and settle
Order-specific output supports delivery and billing; logistics, actual cost, revenue, and margin retain traceability to the requirement.
DIAGNOSTIC EVIDENCE
Diagnose the control that owns the result
If MRP creates no customer-specific supply, verify schedule-line transfer, requirements determination, individual/collective indicator, planning file and MRP result before changing production. If supply exists but the date is not confirmed, diagnose ATP separately.
Sales document/item, schedule line, item and schedule-line categories, strategy group, requirements type/class, transfer flag, requested and confirmed dates.
Individual customer requirement, planning segment, pegging, MRP result, planned order, production order or purchase proposal, and customer reference.
Sales-order stock where used, goods movements, delivery, billing, cost object, variance, settlement, revenue, and margin evidence.
PROJECT MOMENT
One schedule line creates one traceable supply chain
A configured motor sales-order item transfers an individual requirement. MRP creates a pegged planned order and a purchase requisition for a special component. Production receives the motor into sales-order stock, then delivery and billing complete the same customer requirement.
- TOR creates individual demand
- MRP supply retains the customer reference
- ATP confirmation is diagnosed separately
- Delivery, cost, and revenue remain traceable
