The Sales and Operational Planning (S&OP) processes and activities are an essential and strategic element of the ERP Rebuild project scope and design therefore, playing a pivotal role in the overall success of the project.
In parallel to the ERP Rebuild program, the Advanced Planning and Scheduling (APS) project is currently in progress and being executed concurrently, utilizing the Kinaxis Maestro tool (a leading S&OP software solution), to implement a product planning process and solution including the Demand Planning and Sales and Operational Planning functionalities within the Syensqo business.
This document serves as a guide, designed to offer an understanding of the current "As-Is" planning processes, the "As-Is" integration mechanisms, and the "As-Is" overall system landscape associated with the Maestro system, all within the scope of the APS project.
Additionally, this document aims to identify and highlight the critical changes required to ensure that the APS solution aligns seamlessly with the ERP Rebuild project’s goals, objectives and timelines. It outlines the potential adjustments and modifications needed to be made to the existing system design to accommodate the ERP Rebuild related process and solution changes. Furthermore, this document provides a detailed vision for the future state of the integration and system landscape, showcasing how the APS and ERP systems will function cohesively after the rebuild is complete. A proposed approach for data cleansing and cutover, aligned with the ERP rebuild design, is also included to ensure smooth data transition and system upgrades.
APS project includes the following functionalities:

Multiple interfaces are required to connect the Maestro system with SAP ECC (ERP Central Component).
These interfaces will facilitate seamless data exchange and integration between ECC and Maestro, supporting critical business processes such as planning, inventory management, order fulfillment, and reporting. They can be categorized into the following:
| Category | Description |
|---|---|
| Enterprise Structure Data | This includes organizational data such as company codes, plants, storage locations, sales organizations, and distribution channels. Ensuring alignment between SAP ECC and Maestro allows for accurate representation of the organizational hierarchy and dependencies. |
| Config Data | Configuration data includes system settings, rule definitions, and organizational configurations like MRP settings, delivery priorities, and planning parameters. This ensures that ECC and Maestro operate with aligned business rules and logic. |
| Master Data | Master data encompasses key foundational data such as material master, customer master, BOM's, Routings etc... It ensures consistent and accurate information flows between SAP ECC and the Maestro system for efficient operations. |
| Transactional Data (Demand / Supply) | This category includes real-time transaction data such as sales orders, purchase orders, demand signals, supply plans, and stock movements. It supports demand & Supply planning, inventory management processes. |
| Planning Results | These are outputs from planning activities, including demand forecasts, production schedules, procurement plans, and ATP (Available-to-Promise) data. Planning results support Maestro's decision-making and strategic planning functions while aligning with ECC data. |
Below is an overview of the interfaces.
Note: ECC is represented as one line and it comprised both the ECC's

Below is the proposed To-Be system architecture. Below are some of the key things to note comparing with the existing As-Is architecture

The timeline diagram below illustrates the time-phased instance strategy for the APS Project and ERP Rebuild Project. The diagram is divided into two sections: APS and ERP Rebuild, reflecting their respective project timelines.
Instances are represented within the diagram to show how they are strategically aligned with each phase of the APS and ERP Rebuild projects. These instances are mapped to the respective project timelines to reflect key milestones, implementation phases, and decision points. The varying timelines and objectives of each project have led to a staggered deployment of these instances, ensuring that the integration and operational readiness are achieved in a structured, phased manner while supporting the distinct goals of both projects.

Below is the detailed representation of the instances along with the transportation path.

Planning data from Maestro is required in S/4 at each day level during the short-term horizon, i.e., before the planning time fence.
Aggregation of data at weekly or monthly buckets is planned beyond the short-term horizon. However, this approach needs to be confirmed during the detailed design phase, based on various other factors such as ATP (Available to Promise) requirements.
Integration is required between the allotment in Maestro to the PAL tables in SAP. There is already a new interface included to cater to this requirement, however more details of how PAL table is structured will be determined during the detailed design
ATP functionality in SAP requires up-to-date inventory information, production/procurement plans, and delivery priorities to determine accurate delivery dates.
This information will be readily available and detailed during the short-term horizon, ensuring precise commitments. However, for long-term horizons, the data will be aggregated to simplify planning processes and manage larger time frames efficiently.
During the detailed design phase, the following topics should be considered:
Following are some of the important considerations for cutover
The Existing APS Production System Will Not Be Used for Go-Live During the ERP Rebuild Project:
As part of the ERP Rebuild project's go-live strategy, the current APS production system will not be utilized. Instead, a new instance will be implemented to support the transition and operational readiness.
Migration of Planning History to the New Instance:
To ensure continuity and historical reference during the cutover to the new instance, planning history will be migrated as part of the cutover strategy. Two migration options have been identified, and the final choice will be determined during the detailed design phase:
Specialty Polymers (SP) and Global Supply Chain:
The supply chain transaction overlap between the Specialty Polymers legal entities in scope for Group 1 and the Rest of Syensqo is minimal, based on the analysis conducted by the ERP Rebuild team. As a result:
Composites and Rest of Syensqo:
The supply chain transaction overlap between Composites and the Rest of Syensqo is also minimal, as confirmed by the analysis conducted by the APS team. Therefore:
Other Company Codes in the BAU Non-Composites Environment:
For the remaining company codes within the BAU Non-Composites environment, the transaction overlap with the global supply chain is minimal. As a result:
Below is an high level diagram to illustrate the same.

Following are some of the Governance Principles proposed for the project
