A global leader in semiconductor equipment manufacturing was facing a critical bottleneck in its SAP Business Warehouse (BW) operations: a slow, manual, and high-risk change management process that was limiting the pace of system updates and causing frequent production incidents. Rialtes partnered with the organisation to implement Active Control by Basis Technologies, automating transport sequencing and dependency checks across four development environments.
Reduction in Manual Change Management Effort
Faster SAP Change Delivery Cadence
Decrease in Production Downtime
Annual Revenue Supported by Stabilised SAP Landscape
The client is a Tier-1 developer and supplier of critical subsystems, components, and ultra-high purity services for the semiconductor capital equipment and industrial markets. With over $2 billion in annual revenue and a global workforce of more than 7,000 employees, the organisation is one of the largest players in its segment — commanding an estimated 30% of the outsourced gas delivery market for wafer fabrication equipment.
Headquartered in North America, the organisation operates a sprawling international footprint spanning North America, Europe, Asia, and Israel. Its major manufacturing hubs are clustered in Singapore, Malaysia, and Taiwan. The business operates across two divisions: a Products division focused on high-precision manufacturing and integrated subassemblies, and a Services division providing critical aftermarket support, including tool chamber parts cleaning, coating, and micro-contamination analysis.
SAP Business Warehouse (BW) sits at the heart of the organisation's analytical and reporting infrastructure, making the reliability and speed of BW change delivery mission-critical to business operations across all global locations.
The organisation’s SAP BW environment had grown to serve a highly complex, multi-environment landscape — but its change management processes had not kept pace. Slow, manual workflows were creating significant risk, operational delays, and business disruption at a scale the semiconductor industry’s pace of change simply could not tolerate.
Rialtes recommended and implemented Active Control by Basis Technologies as the core solution to automate and govern SAP BW change delivery — eliminating manual bottlenecks and de-risking transport management across the organisation’s four-environment SAP landscape.
The implementation was structured in deliberate phases to ensure zero disruption to live SAP BW operations while progressively automating and governing the change delivery pipeline:
Conducted structured knowledge transfer across all functional and technical streams; stabilised day-to-day support operations from day one.
Defined support processes, SLAs, governance structure, and communication channels across business units and time zones.
Established incident, problem, and change management frameworks aligned to the global SAP S/4HANA landscape.
Implemented proactive monitoring and operational reporting mechanisms for critical business processes, interfaces, and batch jobs.
Aligned the BW change delivery improvements with the organisation’s broader multi-year SAP S/4HANA migration roadmap, ensuring the automated change framework scales with the evolving landscape.

The adoption of Active Control and an automated change delivery model drove immediate and sustained improvements across the organisation’s global SAP BW operations:
| Outcome Area | Quantifiable Impact | How It Was Achieved |
|---|---|---|
| Production Downtime | ~50% reduction in downtime | Automated change delivery eliminated error-prone manual transports that triggered system disruptions |
| Change Delivery Speed | ~40% faster delivery cadence | Automated transport sequencing removed manual bottlenecks, enabling more frequent, reliable SAP updates |
| Manual Effort | ~60% reduction in manual change management | Automated dependency checks and discrepancy validation replaced labour-intensive manual processes |
| Audit & Compliance | Minimised manual audit overhead | Active Control provided a governed, traceable change trail — reducing compliance effort for IT and operations teams |
| Business Continuity | Near-elimination of upgrade-related freezes | Structured, automated phasing of changes removed the need for extended operational freezes during upgrades |
| Strategic Capacity | IT teams refocused on strategic priorities | Reduction in reactive incident management freed capacity for SAP S/4HANA modernisation and business-driven enhancements |
Beyond operational improvements, the organisation’s IT teams, freed from the burden of manual change coordination, are now better positioned to contribute to the ongoing SAP S/4HANA modernisation journey and deliver faster, business-aligned innovation across the enterprise.
