What’s new in Supply Chain Suite (SCS) 2512

We’re excited to announce the release of Supply Chain Suite (SCS) 2512! Whether you’re planning upgrades, managing licenses, or building optimization models every day, this release has something important for you.

Supply Chain Suite is part of the Siemens Xcelerator portfolio, the comprehensive and integrated portfolio of software, hardware and services. SCS helps you optimize all of your logistics processes to make logistics leaner, faster and more efficient. It consolidates data from various IT systems, providing a holistic, data-driven view of the supply chain.

SCS 2512 brings together three things our customers have been asking for: better optimization results (especially for transportation planning), easier troubleshooting and performance tuning, and more flexible deployment options across cloud, on-premise, or hybrid environments. Plus, licensing is being modernized to align with the rest of Siemens Digital Industries Software.

Highlight features in this release

• Integrated Tour and Load Optimization
• Enhanced Container Loading
• Performance Profiler
• PostgreSQL Database Support
• Usage Monitoring and Limits
• AI and Machine Learning Components
• Location Planning Improvements
• Better File and Data Handling
• Static Publisher
• New SALT Licensing
• Modular Licensing with Capability Packages and User Types
• Updated Release Cycle

Integrated tour and load optimization

This is the feature many customers have been waiting for. SCS 2512 enables the optimization of routes and 3D loading together in a single optimization run — no more planning tours and then manually figuring out how to load the trucks.

Key capabilities include:

• Define stackability rules (which items can go on top of others)
• Control item rotation (which orientations are allowed)
• Optimize loading sequence (ensuring items are accessible at the right delivery stop)
• Choose loading direction (front, back, left, or right side loading)

The result: execution-ready plans that maximize truck utilization while ensuring drivers can actually load and unload efficiently. It’s the difference between a theoretical plan and one that works in practice.

Enhanced container loading

For teams working with shipping containers or warehouse pallets, the 3D bin packing component now includes a container mode with realistic stacking rules.

What’s different:

• Items must rest on other items or the container bottom (no floating)
• Support for weight-based optimization
• Better handling of container-specific constraints

This enhancement is particularly useful for ocean freight, LTL shipments, and warehouse operations where stacking stability matters.

Performance profiler

Building a model that runs slower than expected? Identifying the bottleneck has always been a challenge. The new Performance Profiler shows exactly where a model spends its time — down to individual operations.

How it works:

• Run models with profiling enabled
• See a visual timeline of every operation
• Identify bottlenecks (joins on large tables, complex transformations, etc.)
• Optimize the slow parts
• Re-run and compare

Who benefits:

• Modelers can troubleshoot performance issues independently
• Web service developers can optimize response times
• Support teams get detailed diagnostics when help is needed

Profiling results can be saved and shared with colleagues or support for collaborative troubleshooting.

PostgreSQL Database support

SCS 2512 now works with PostgreSQL as an alternative to MS SQL Server, especially for cloud deployments.

Why this matters:

• Lower cloud hosting costs
• More database options for infrastructure teams
• Same SCS capabilities regardless of database choice

Usage monitoring and limits

New tools enable tracking and controlling how web services are used:

• Set usage limits (by time, transaction count, or both)
• Get email notifications when limits are approaching
• Export monthly usage reports
• Support soft limits (warning) or hard limits (block access)

Practical uses include: monitoring consumption across departments, controlling costs for cloud-based services, enabling internal chargeback models, and offering usage-based pricing to customers.

AI and machine learning components

SCS 2512 expands the AI/ML toolkit with components that are practical and ready to use — building on the broader Siemens vision of applying AI across demand planning, inventory management, production scheduling, and logistics execution.

Forecast component

Build time series forecasts directly in SCS using methods like exponential smoothing, moving averages, or SARIMAX. This is ideal for demand forecasting, capacity planning, or any scenario with historical patterns.

ML trainer and prediction

• Train machine learning models in SCS
• Import pre-trained models from Python (scikit-learn, etc.) in ONNX format
• Use predictions directly in optimization workflows

Regression component

Estimate relationships between variables — useful for cost estimation, parameter tuning, or understanding what drives key metrics.

AI-Assisted Expression Editor (Experimental)

Location planning improvements

For users of the Location Planning component, SCS 2512 delivers:

• Faster infeasibility detection — quickly identifies modeling errors (like mismatched units)
• Better performance on large problems through internal parameter tuning
• Clearer error messages when something’s wrong

Small improvements individually, but they add up significantly when running multiple scenarios for network optimization and location evaluation.

Better file and data handling

S3 file system – historical view

Accidentally deleted a file? Previous versions can now be restored without calling IT: open the file system with historical view, select the date when the file existed, and download and restore it.

Improved External Data Component

• Better error messages when file operations fail
• Easier switching between file systems (local, network, S3)
• Store and edit Excel files directly in SCS

Stream Providers

Build models using local files during development, then switch to production file systems (network share or S3) without changing external data components. Just point the stream provider to the new location.

Static Publisher: Simpler Deployment

The new Static Publisher enables deploying web services without a database:

• Export calculation logic as DTF files
• Deploy them with the SCS server
• Call them via REST API

This is ideal for lightweight deployments, simplified infrastructure, and scenarios where a full database isn’t needed.

New licensing: SALT starting in 2026

What’s Changing

SCS 2512 introduces SALT (Siemens Advanced License Technology) — the same licensing system used across Siemens software products.

Key milestones:

• SCS 2512 released with SALT licensing
• October 1, 2026: All renewals and expansions require version 2512 or later

What this means for you

• License administrators: SALT simplifies provisioning and gives better control over which capabilities different teams can access.
• Modelers and analysts: Not much changes in day-to-day work — the same capabilities remain available, just with a more streamlined licensing experience.

Bottom line: Plan to upgrade before October 2026. We recommend doing it sooner to take advantage of all the new features.

Modular licensing: Capability Packages and user types

SCS 2512 introduces a more flexible licensing model with two key components: capability packages (what features you can access) and user types (how you interact with the system).

Capability Packages

Instead of licensing “all of SCS,” specific capabilities can now be licensed individually:

Core Package (mandatory):

• Basic modeling and simulation
• Digital twin capabilities[6]
• Standard components

Optional Optimization Packages:

• Transportation Optimization — Tour planning, routing, load optimization
• Intra Logistics Optimization — Warehouse operations, bin packing
• Network Optimization — Location planning, flow optimization[5]
• Rate Optimization — Freight rate calculation

Add-Ons:

• Maps and distance calculation (PTV)
• Gurobi optimization booster (now included in all 2512 packages — just needs a license)
• Enhanced support (Silver/Gold SLA)

User Types

Three distinct user types align licensing with how people actually work:

User Type	Who It’s For	What They Can Do
Viewers	Executives & stakeholders	Access dashboards and visualizations through Home Screens; view data, apply filters, sort, and search
Users	Planners & analysts	Everything Viewers can do, plus edit input data, run optimizations, and generate new results
Modelers	Engineers building solutions	Full access — build and modify models, create use cases, configure Home Screens, use all components

This structure means teams can license only the access level and features each person needs, reduce costs by right-sizing licenses, and better align spending with actual usage.[1]

Updated release cycle

SCS 2512 also introduces a new release cadence:

• One Long-Term Support (LTS) version per year (supported for 18 months)
• Quarterly releases for continuous improvements
• Patch releases every 3 months for LTS versions
• On-demand patches when needed

The LTS version will typically be the December release (2512, 2612, etc.).

What should you do next?

If you’re a license administrator: Review the SALT licensing transition timeline, plan your upgrade before October 2026, assess which user types and capability packages your team needs, and contact your Siemens representative to discuss migration.

If you’re a modeler: Check out the integrated tour and load optimization, try the Performance Profiler on your slowest models, explore the AI/ML components for forecasting, and test the new container loading mode if relevant.

If you manage cloud deployments: Evaluate PostgreSQL as a database option, set up usage limits for web services, and review the Static Publisher for lightweight scenarios.
