SAP: Manufacturing

SAP for manufacturing

SAP that knows what the shop floor actually did. We implement and migrate SAP S/4HANA for manufacturers, connect production planning, quality and maintenance to the MES and machines on the line, and clean up the custom code that makes every upgrade painful. Senior SAP and integration engineers own the design, AI coding agents carry the volume, and every line is reviewed by a human.

Key highlights

We implement, migrate and support SAP S/4HANA for discrete and process manufacturers, covering PP, PP/DS, QM, PM, MM and EWM.
Mainstream maintenance for SAP ECC 6.0 ends on 31 December 2027, so most ECC plants need a migration plan now, not in 2027.
We connect SAP to the shop floor through SAP Digital Manufacturing or your existing MES, so confirmations and consumption post in near real time.
Custom ABAP is reviewed object by object: kept, rewritten for S/4HANA, moved to SAP BTP, or retired.
We are an independent engineering team, not an SAP partner. Licences stay with SAP or your reseller.

SAP problems we see in manufacturing

Most manufacturing SAP systems were built well a decade or more ago. The plant has changed since, and the system has been patched to keep up rather than redesigned.

ECC with a deadline. Mainstream maintenance for SAP ECC 6.0 ends at the end of 2027, with paid extended maintenance only to 2030. A migration that touches every plant, BOM and routing cannot start late.

Production orders confirmed hours late. Operators confirm at end of shift or a planner keys it in the next morning, so stock, WIP and product costing are wrong in SAP while the floor already knows the real numbers.

MRP output nobody trusts. Classic MRP plans to infinite capacity, so planners export to spreadsheets to build a schedule that respects the bottleneck machine, then the plan in SAP and the plan on the wall drift apart.

Thousands of custom objects. Z transactions, user exits and modified standard code written for long gone requirements. Nobody knows which are still used, so every upgrade or migration estimate balloons.

Quality data outside SAP. Inspection results live in a separate system or on paper, so usage decisions, batch status and certificates of analysis lag behind production and recalls need manual reconstruction.

Maintenance disconnected from the machines. PM notifications are raised by phone or email after a breakdown, and the condition data that would have warned the planner never reaches SAP at all.

Capabilities

Our SAP capabilities for manufacturing

We work across the core manufacturing modules and the integrations that tie SAP to the plant floor.

Production planning and PP/DS

Master data for BOMs, routings, work centres and production versions, MRP and MRP Live, and embedded PP/DS in S/4HANA for finite capacity scheduling, sequencing and setup optimisation on the detailed scheduling planning board.

MES and shop floor integration

Production orders, BOMs and routings sent down to SAP Digital Manufacturing or a third party MES, with confirmations, goods movements and scrap posted back. Retry queues mean nothing is lost if either side is offline.

Quality management

Inspection plans, inspection lots on goods receipt and in process, results recording, usage decisions, batch classification and quality notifications, with lab or inspection station results flowing into SAP QM automatically.

Plant maintenance and asset data

Functional locations, equipment, maintenance plans and work orders in SAP PM, with condition monitoring and IIoT alerts raising notifications automatically instead of by phone after a breakdown.

Variant configuration and PLM

Configurable materials and object dependencies for make to order products, and engineering BOM to manufacturing BOM handover from PLM systems such as Siemens Teamcenter or PTC Windchill into SAP.

Custom code remediation

Usage analysis and ATC checks on your ABAP, then each object is retired, adapted for S/4HANA simplifications, or rebuilt as a clean side by side extension on SAP BTP so the core stays upgradeable.

How we deliver

From ECC audit to a plant that runs on S/4HANA

01
Assess
We review your system, custom code usage, interfaces to MES, PLM and machines, and the planning and quality processes per plant. Output: a written migration approach, scope and risk list.
02
Design
Fit to standard workshops for PP, QM, PM and inventory, a target integration architecture for the shop floor, and a decision on each custom object before any build starts.
03
Build and migrate
Configuration, extensions on SAP BTP, interface build and data migration with repeated mock loads. A pilot plant goes live first, running in parallel checks against current reporting.
04
Run and improve
Hypercare, then ongoing support with clear response times. We roll the template to further plants and add PP/DS scheduling, predictive maintenance or analytics once the core is stable.

Compliance and controls in manufacturing SAP

Manufacturing SAP systems carry financial controls, product traceability and, increasingly, e-invoicing obligations. We design for them inside the project rather than after go live.

SOX and ITGC controls Segregation of duties in SAP roles ISO 9001 traceability support IATF 16949 support (automotive suppliers) FDA 21 CFR Part 11 (regulated plants) IEC 62443 aligned OT connectivity GDPR and UK GDPR Germany B2B e-invoicing

Financial controls survive the migration. Inventory valuation, production order settlement and period end steps are tested against your SOX and internal control matrix, and roles are designed so segregation of duties conflicts are resolved before go live, not found by the auditor.

Traceability from lot to shipment. Batch management, QM results and goods movements are linked so a where used or where from query on a raw material lot can be answered from SAP, supporting ISO 9001 and IATF 16949 audits and customer complaints.

E-invoicing mandates are in scope. Germany already requires businesses to receive structured e-invoices, with issuing obligations phasing in from 1 January 2027 and 2028, and France started phased B2B e-invoicing in September 2026. We plan output formats and SAP Document Compliance or your chosen provider into the design.

FAQ

Common questions

When does SAP ECC support end for manufacturers?

Mainstream maintenance for SAP ECC 6.0 ends on 31 December 2027. SAP offers extended maintenance at an extra fee to the end of 2030 for systems on recent enhancement packages. Because a manufacturing migration has to cover every plant, BOM, routing and interface, most companies should be in assessment or design by now.

Do we need SAP Digital Manufacturing, or can we keep our current MES?

You can keep your current MES. S/4HANA integrates with third party MES through standard interfaces such as IDoc, BAPI and OData. SAP Digital Manufacturing is worth considering if your MES is end of life or you want one vendor stack, and we help you compare both on your actual processes.

Should we use embedded PP/DS or stay with classic MRP?

Stay with classic MRP unless finite capacity scheduling is a real problem. Embedded PP/DS in S/4HANA adds detailed scheduling, sequencing and setup optimisation, but it brings extra master data and planner training. We usually start it on the one or two bottleneck resources where planners already work around SAP in spreadsheets.

What happens to our custom ABAP during migration?

Each object gets a decision before the build. We run usage analysis and ATC checks, retire code that is no longer used, adapt what S/4HANA simplifications break, and move suitable logic to side by side extensions on SAP BTP so the core stays close to standard.

Are you an SAP partner?

No. RG INSYS is an independent engineering company and does not claim SAP partner status or SAP certifications. You license SAP directly from SAP or your reseller, and we work on your system, your repositories and your transport landscape under NDA with full IP assignment.

Can you support our SAP system after go live?

Yes. We provide application management support for S/4HANA and ECC with agreed response times, covering incidents, small changes, interface monitoring and release upgrades. See our SAP support and AMS service for how it is structured.
