Oracle 1Z0-1066-26 Real Exam Questions [October 2026 Update]

Supply chain planning professionals who work inside Oracle Planning and Collaboration Cloud every day – running demand plans, managing supply plan exceptions, collaborating with suppliers on order forecasts – often underestimate how differently the 1Z0-1066-26 exam tests that knowledge. The exam is not asking what you do inside the planning work area. It is asking how the system was configured to make what you do possible: why the demand plan produces the forecast it produces, why the supply plan recommends what it recommends, and what configuration decision – in the Supply Network Model, in the data collection setup, in the backlog planning options – is responsible when the planning outputs do not reflect the reality they should.

The exam’s most consistently tested configuration object is the Supply Network Model. Every planning process in Oracle Planning and Collaboration Cloud – demand forecasting, supply planning, backlog management, supply chain collaboration – depends on the Supply Network Model as its reference for the physical supply chain topology. The Supply Network Model defines the organisations that participate in planning (manufacturing plants, warehouses, customer zones, supplier sites), the sourcing rules that specify where supply for each item can come from, the bills of distribution that define multi-echelon replenishment paths, and the assignment sets that link sourcing rules to planning. A supply plan that produces no recommendations, a demand plan that does not reflect the correct organisation structure, or a backlog plan that cannot find supply – all lead back to the Supply Network Model as the first configuration area to check.

The exam separates candidates who understand Backlog Management as a distinct Oracle Cloud SCM planning module from those who treat it as part of Supply Planning. Backlog Management manages customer order fulfillment priority – it determines, given limited supply, which customer orders should be fulfilled first and how available supply should be allocated across competing demands. It uses Demand Priority Rules (which define the attributes used to rank customer orders – customer priority, order type, promise date), Backlog Planning Rules (which define what supply can be used to satisfy demand), and Supply Allocation Rules (which define how supply is distributed across allocation hierarchy levels) as its three independent configuration objects. All three must be correctly configured before Backlog Management can produce a usable backlog plan.

Exam Snapshot

Domain 1: Using Demand Management

Demand plans are the primary output of Demand Management – statistical forecasts of future customer demand for each item and organisation combination. A demand plan is run against collected historical demand data (sales order history, shipment history, or a combination) and uses configurable statistical forecasting methods to project demand forward over a defined planning horizon.

Demand plan options define the key parameters for a plan run: the planning horizon (how far forward the forecast extends), the time bucket (daily, weekly, monthly – the granularity at which forecast data is generated), the items and organisations in scope, and the demand history collection source. The exam tests demand plan options as the configuration that determines what a demand plan will produce – scenarios where a demand plan produces an unexpected result require diagnosing which plan option is responsible.

Forecasting profiles and methods: A forecasting profile defines the statistical model used to generate the forecast for a group of items. Oracle Planning and Collaboration Cloud supports multiple forecasting methods including Bayesian (which adapts model parameters to historical patterns), Holt-Winters (seasonal smoothing), and machine learning-based methods for 2026. Different item groups benefit from different methods based on their demand pattern – high-volume regular items versus intermittent demand items require different forecasting approaches.

Demand classes segment customer demand into categories – retail channel, distributor channel, e-commerce – that are tracked separately in the demand plan. Forecasts can be generated by demand class, allowing planners to understand how much of total demand comes from each channel and to allocate supply to channels with different priority levels. The exam tests demand classes as a Demand Management configuration object separate from item segments.

Sales Orders Measure: In Oracle Planning Cloud, the Sales Orders measure tracks actual customer order demand for use in supply planning. When actual sales orders exist for a period within the demand plan horizon, planners can blend statistical forecast data with actual order data – using sales orders to replace or supplement the statistical forecast in the near horizon where demand is already firm.

Domain 2: Using Supply Plans

A supply plan is a constrained or unconstrained recommendation of what supply to create – purchase orders, manufacturing work orders, transfer orders – to satisfy projected demand over the planning horizon.

Supply plan options control the most fundamental supply planning parameters: the planning horizon, time bucket configuration, whether the plan is constrained (respects capacity limits) or unconstrained (ignores capacity), the planned items and organisations, and which demand sources drive the plan (demand plan output, sales orders, safety stock replenishment requirements). The exam tests supply plan option configuration as the first explanation to investigate when a supply plan produces unexpected recommendations.

Policy assignment sets in supply planning define the inventory policies applied to each item – safety stock levels, reorder point logic, and lot sizing rules. The policy assignment set is assigned to the supply plan and determines how conservative or aggressive the plan is in building buffer inventory. The exam tests policy assignment sets as a distinct supply plan configuration object.

Exceptions in supply plans: The supply planning engine generates exceptions when it identifies a planning problem – a demand that cannot be satisfied within the standard planning horizon, a resource that is over-committed, a supply that arrives too late to prevent a shortage. Exception types include: Late Supply Pegged to Sales Order, Shortage in a Period, Excess Inventory, and Resource Overload. The exam tests exception types as the mechanism that surfaces planning issues rather than requiring planners to manually inspect all supply and demand.

Sourcing allocation splits: When multiple sourcing rules exist for the same item-organisation combination – for example, 70% manufactured domestically and 30% purchased from an external supplier – Oracle Supply Planning uses sourcing allocation splits to distribute the planned supply quantity across the sources in the configured percentage ratio. The exam tests allocation splits as the mechanism for multi-source supply strategies.

Domain 3: Managing the Supply Network Model

The Supply Network Model is the foundational supply chain topology configuration that all Oracle Supply Chain Planning modules share. It defines: which organisations (plants, warehouses, customer zones, supplier sites) participate in planning; the items those organisations manage; the sourcing rules that define supply relationships; the bills of distribution for multi-tier replenishment paths; and the assignment sets that activate sourcing rules for specific plan runs.

Sourcing rules define where supply for an item in a destination organisation can come from: a make source (manufacture at the receiving plant), a buy source (purchase from a supplier), or a transfer source (transfer from another internal organisation). Each sourcing rule specifies the source, the lead time, and the sourcing allocation percentage (if multiple sources exist). A sourcing rule must be assigned via an assignment set before it is active in any planning run.

Bills of distribution define multi-echelon replenishment paths – the sequence of intermediate warehouses between a supply source and the final destination. For example: a regional distribution center replenishes from a central warehouse, which in turn replenishes from the manufacturing plant. Bills of distribution allow supply planning to model and optimise inventory positions across the full replenishment chain.

Assignment sets are the linking mechanism between sourcing rules (and bills of distribution) and the planning organisations that use them. An assignment set groups sourcing rule assignments and is referenced by the supply plan, the backlog plan, or Global Order Promising to determine which sourcing rules apply. The exam tests assignment sets as the required intermediary – a sourcing rule not attached to an assignment set, or an assignment set not referenced by the plan, is invisible to the planning engine.

Item attributes for supply planning: Items carry planning-relevant attributes that the supply planning engine uses to generate correct recommendations: the planning method (MRP, min-max, reorder point), the fixed order quantity, the minimum order quantity, the lead time components (preprocessing, processing, postprocessing), and the make-or-buy designation. The exam tests item attributes as the granular item-level configuration that shapes the specific supply recommendation for each item.

Drop shipments in the Supply Network Model: Drop shipment sourcing rules define a fulfillment path where the supplier ships directly to the customer – bypassing the company’s own warehouse. The Supply Network Model must include a drop-ship validation organisation and correctly configured drop-ship sourcing rules for planning to correctly model drop-ship demand and supply.

Domain 4: Using Backlog Management

Backlog Management is the Oracle Cloud SCM module that determines customer order fulfillment priority and supply allocation when demand exceeds available supply. Unlike supply planning (which plans future supply creation), Backlog Management works with near-term existing supply and committed customer orders.

Demand Priority Rules define how customer orders are ranked for fulfillment priority when supply is insufficient to fill all orders. The rule specifies the attributes used to rank orders (customer priority class, order type, requested date, promise date) and the sequence in which those attributes are evaluated. When supply is limited, orders ranked higher by the demand priority rule receive supply first.

Backlog Planning Rules define what supply can be used to satisfy demand in a backlog plan run. The rule specifies: whether the plan uses on-hand inventory, in-transit supply, planned supply, or a combination; the search scope for available supply (the supply chain availability search mode); and whether the plan is run in a supply-chain-wide availability search mode or a simpler on-hand-only mode.

Supply Allocation Rules define how supply is distributed across allocation hierarchy levels when supply is insufficient to satisfy all demand. The allocation hierarchy has a maximum of three levels – for example, by region at the top level, by customer priority class at the second level, and by order type at the third. The exam tests the three-level maximum as a specific configuration constraint.

Backlog plan runs execute the backlog planning engine against the configured demand priority rules, backlog planning rules, and supply allocation rules to produce a prioritised fulfillment plan. The exam tests the Start Backlog Planning scheduled process as the mechanism that triggers a backlog plan run, and the parameters available when scheduling it (plan name, backlog priority rule selection).

Domain 5: Managing Supply Chain Collaboration

Supply Chain Collaboration allows Oracle Cloud SCM planning teams to share planning data with trading partners – primarily suppliers – and receive their responses directly into the planning system, without requiring partners to have Oracle Cloud access of their own.

Order forecast collaboration: The planning team publishes a projected order forecast to each supplier – a time-phased projection of expected purchase order quantities based on current supply plan output. Suppliers review the forecast, confirm their ability to fulfill the projected quantities, or respond with exceptions where they cannot. The confirmed supplier responses feed back into supply planning to create more realistic supply plans.

The “Publish Order Forecast Using Sourcing Rules” profile option controls whether the order forecast published to each supplier is calculated using the sourcing rules defined in the Supply Network Model. When this profile option is activated, the published order forecast reflects the sourcing percentages and lead times configured in the sourcing rules. The exam tests this profile option as the specific configuration that aligns published forecasts with Supply Network Model sourcing logic.

Contract management in collaboration: Supply Chain Collaboration supports collaborative contract management – sharing purchase contract terms with suppliers and tracking supplier acknowledgements of contract changes. This extends collaboration beyond order forecasting to the contractual supply relationship.

Customer demand management via collaboration: On the customer side, Supply Chain Collaboration allows customers to share their planned demand (their own forecasts or purchase plans) directly with the planning team. This customer-provided demand can be incorporated into the demand plan as an additional demand source alongside statistical forecasts and actual sales orders.

Domain 6: Configuring Oracle Supply Chain Planning Cloud

Data collection is the process by which Oracle Supply Chain Planning Cloud pulls master data and transaction data from Oracle SCM Cloud (and optionally from external ERP systems) into the planning data repository. The planning data repository is the dedicated data store the planning engine operates against – it is separate from the operational Oracle SCM Cloud transaction tables.

Data collection types: Full collection replaces all planning data for the collected entities with current values from the source system – appropriate for initial setup or when large-scale data corrections are needed. Net change collection collects only the data that has changed since the last collection run – appropriate for regular incremental collections that keep planning data current without the overhead of a full re-collection.

Segmentation in planning: Segmentation groups items and organisations into planning segments – product families or clusters that share common planning behaviour (similar demand patterns, similar supply lead times, similar service level targets). Segmentation allows different planning policies to be applied to different item groups rather than applying one-size-fits-all planning parameters across all items.

Planning work areas: Oracle Planning and Collaboration Cloud provides dedicated work areas for each planning function – the Supply Planning work area, the Demand Management work area, the Backlog Management work area, and the Supply Chain Collaboration work area. Each work area provides the tables, graphs, and exception views appropriate for that planning function. The exam tests work area configuration – the page layout, tile configuration, and measure selection within each work area – as implementation tasks rather than user navigation tasks.

5 Study Tips for Oracle 1Z0-1066-26

• Study the Supply Network Model architecture in depth – sourcing rules, bills of distribution, and assignment sets as three linked objects, and understand why a missing assignment set means a sourcing rule is invisible to the planning engine.

FAQ’s

What is the Oracle 1Z0-1066-26 certification?

1Z0-1066-26 is the Oracle Planning and Collaboration Cloud 2026 Implementation Professional exam. It validates expertise in implementing Oracle Supply Chain Planning Cloud – covering demand management, supply planning, Supply Network Model configuration, Backlog Management, supply chain collaboration, and planning cloud setup.

What is the Supply Network Model in Oracle Planning and Collaboration Cloud?

The Supply Network Model is the foundational supply chain topology configuration – it defines which organisations participate in planning, the sourcing rules for each item, bills of distribution for multi-echelon replenishment, and the assignment sets that link sourcing rules to plan runs. All planning modules depend on the Supply Network Model as their reference for the physical supply chain structure.

What is the difference between a sourcing rule and a bill of distribution?

A sourcing rule defines a single-echelon supply relationship – where supply for an item in a destination organisation comes from (make, buy from supplier, or transfer from one other organisation). A bill of distribution defines a multi-echelon replenishment path – a chain of intermediate organisations through which supply flows from a source to a final destination.

What is Backlog Management and how does it differ from Supply Planning?

Supply Planning generates future supply recommendations (purchase orders, work orders, transfers) to satisfy projected demand. Backlog Management manages near-term committed customer orders against existing and in-transit supply – determining which orders get fulfilled first when supply is insufficient to fill all orders. Backlog Management uses Demand Priority Rules, Backlog Planning Rules, and Supply Allocation Rules; Supply Planning uses plan options, policy assignment sets, and sourcing rules.

What is the maximum number of levels in a Backlog Management supply allocation hierarchy?

The maximum is three levels. The supply allocation hierarchy distributes available supply across allocation groupings – for example, by region, by customer priority class, and by order type – with each level receiving an allocation of supply before passing unallocated supply to the next level.

What does the “Publish Order Forecast Using Sourcing Rules” profile option do?

This profile option controls whether the order forecast published to suppliers via Supply Chain Collaboration reflects the sourcing percentages and lead times defined in the Supply Network Model’s sourcing rules. When activated, the published forecast aligns with Supply Network Model sourcing logic rather than publishing unmodified plan output.

What are data collection types in Oracle Supply Chain Planning?

Full collection replaces all planning data for the collected entity types with current values from the source system – used for initial implementation or after major data corrections. Net change collection collects only data that has changed since the last collection run – used for regular incremental updates to keep planning data current.

Is there a delta exam available for candidates upgrading from a prior year?

Yes. The Delta exam 1D0-1066-26-D is available for candidates holding the prior-year Oracle Planning and Collaboration Cloud certification who want to upgrade to the 2026 version rather than sitting the full exam again.
