ATP process map as a text catalogue.
This companion page presents the process areas from the interactive map as normal text. It is useful for linear reading, sharing, accessibility, and deeper review of each ATP topic.
Planning integration
ATP translates planning constraints into concrete promise decisions.
Planning and ATP are deeply connected. Planning provides the availability picture: future supply, product-group availability, market reservations, customer priorities, and other constraints. ATP translates this input into concrete promise decisions. The influence also works the other way around: advanced ATP capabilities can unlock planning scenarios that were difficult in a legacy ERP setup, such as flexible source determination, allocation logic, or controlled use of constrained supply.
Business outcome: Planning decisions become executable confirmation logic instead of remaining a disconnected forecast.
High level availability
PAL lets ATP work on the same level as business planning.
Product Allocation (PAL) allows ATP to work naturally on planning levels instead of being limited to detailed stock availability on SKU level. Supply constraints may exist on a higher planning level, such as product group, collection, market, customer group, capacity bucket, textile group, component availability, or production capacity. SizeGrid designs integrations from external planning applications or SAP tools such as CAR into S/4HANA so these limits can influence order confirmation, reservation logic, prioritization, and supply distribution.
Business outcome: High-level business constraints become ATP-relevant availability limits.
Committed availability
Production commitments convert aggregated plans into SKUs, plants, dates, and quantities.
External planning may define supply on an aggregated level, such as product group, collection, market, or capacity bucket. Production planning then translates this into specific SKUs, plants, dates, and quantities so MRP and manufacturing processes can run. The detailed availability picture can differ from the original high-level plan because of capacity changes, component shortages, production sequencing, or plant-specific restrictions. SizeGrid models these processes, integrates external planning input into production, and broadcasts committed SKU-level availability back to local markets and ATP processes, including hybrid landscapes where some production plants remain in legacy systems during transformation.
Business outcome: Markets and ATP receive a realistic committed availability picture from production.
Combining availability levels
Planned and committed supply need one reliable market view.
Aggregated availability combines planned and committed supply into one market-relevant view. The challenge is that planning and production often work on different levels. Planning may provide availability by product group, collection, or market, while production creates committed availability by SKU, plant, date, and quantity. One of the biggest risks is double counting planned supply that has already been converted into detailed production commitments. SizeGrid helps define the logic for combining these sources correctly so markets receive a consistent picture for allocation, distribution, and ATP confirmation.
Business outcome: The same supply is not promised twice, and markets can trust the availability picture.
SizeGrid Add-On: Fair proportion distribution
Constrained supply should follow business priorities, not only order-entry timing.
Fair cross-market distribution is a SizeGrid custom solution for controlled supply allocation across markets. When supply is limited, standard ATP processes may confirm orders mainly based on timing: the market that enters orders first can consume a disproportionate share of available stock. The SizeGrid ARUN-based add-on compares demand across markets, applies fair-share rules, protects supply for selected regions, and supports transparent redistribution based on business criteria such as forecast, allocation share, market priority, or strategic demand.
Business outcome: Companies move from simple stock consumption to a controlled, business-driven confirmation process.
ATP snapshots with versions
External systems need stable availability views even when ATP changes every second.
ATP availability is not static. It can change every second, while external systems need reliable and up-to-date availability information. This is more complex than a simple stock export because availability may depend on customer group, sales channel, market, product segment, allocation logic, supply protection, or other ATP rules. SizeGrid combines SAP standard mass ATP calculation mechanisms with custom logic to generate fast, reliable, versioned, and business-relevant availability snapshots for external use.
Business outcome: E-commerce, B2B, marketplace, and planning tools can consume a dependable versioned availability feed.
Multi-level ATP in sales documents
Sales documents can evaluate several availability sources in one promise logic.
Multi-level ATP combines committed SKU-level supply with higher-level planned or allocated availability in sales-document confirmation logic. This is useful when the company needs to promise what is already committed, what is protected at a product-group or market level, and what can be promised later through planning or production. SizeGrid defines the sequence, horizons, data levels, and exception logic so ATP can operate across planned and committed availability without confusing users or over-promising supply.
Business outcome: Sales teams get a more nuanced confirmation process than a simple yes/no stock check.
Prioritization strategies
ATP can protect important demand while keeping operational flexibility.
In complex ATP scenarios, companies sometimes need more than basic first-in-first-out confirmation. Prioritization can combine advanced FIFO, customer priority, market rules, order type, product segment, business event, campaign window, and exception controls. SizeGrid helps design prioritization strategies that are transparent enough for users, robust enough for automation, and flexible enough for customer-service teams.
Business outcome: Scarce supply is confirmed according to a business strategy instead of accidental timing.
Requirement / supply segmentation
Segmentation separates supply and demand by business purpose.
Stock and requirement segmentation is a powerful capability for separating supply and demand by business purpose. It can protect regional supply, channels, customer groups, campaigns, packing-based flows, or other scenarios. SizeGrid uses segmentation to make ATP, allocation, MRP, and delivery execution more precise, especially in realistic and complex S/4HANA transformation processes.
Business outcome: Supply is reserved, protected, and consumed according to the right business context.
Procure to order, also for STOs
Internal replenishment can be tied more tightly to real demand.
Procure-to-order is a classical SAP process that connects demand directly with procurement and replenishment. Extending the logic to stock transport orders can help reserve supply across internal logistics networks, link planned movements to real customer or market demand, and improve control in multi-plant or hybrid landscapes. SizeGrid designs this process so reservation and availability logic remain transparent across complex logistics networks.
Business outcome: Supply movement is connected to demand instead of becoming an isolated logistics step.
Prepacks but easy
Packing logic should support the business without creating unnecessary master-data weight.
Prepacking is a classical logistics process where goods are distributed in predefined size or quantity combinations. In fashion, lifestyle, and retail businesses this can become complex when traditional prepack article management creates a heavy master-data footprint. SizeGrid designs flexible prepack logic so packing configurations, size curves, availability, and sales commitments can be handled with less operational friction.
Business outcome: Prepack flows become easier to maintain while still supporting ATP and delivery execution.
ATP in eCom orders
Fast external orders need ATP logic that is accurate, automated, and channel-aware.
E-commerce orders are often technically created as fast, high-volume, externally generated orders with very little tolerance for manual correction. ATP has to consider channel-specific rules, stock protection, allocation, snapshots, customer expectations, and downstream delivery feasibility. SizeGrid designs e-commerce ATP processes so orders can be confirmed quickly, reliably, and in line with business priorities.
Business outcome: Online channels receive accurate confirmations without weakening wholesale or strategic supply rules.
Supply assignment (ARUN)
Supply assignment makes confirmation and release decisions more controlled.
ARUN, or Supply Assignment, is one of the most powerful tools for matching constrained supply with demand in a transparent and business-driven way. It enables companies to re-evaluate confirmations, protect selected markets or customers, apply priority rules, and redistribute supply without relying only on order-entry sequence or manual intervention. SizeGrid uses ARUN both as a standard capability and as a foundation for custom allocation logic.
Business outcome: Demand and supply can be matched again when priorities, quantities, or dates change.
Delivery creation with control
Execution should not break the promise logic created upstream.
Delivery creation looks like one of the simplest areas of logistics, but it often determines whether ATP decisions become reliable execution. Timing, partial deliveries, release waves, delivery blocks, supply assignment, and prioritization all influence what actually ships. SizeGrid helps design delivery creation so it follows ATP logic and supports transparent, business-driven execution.
Business outcome: The final delivery step remains aligned with allocation, prioritization, and ATP confirmations.
