Build and modernize a dependable SAP data warehouse while preserving the rules, history and controls your business relies on.
Keep business meaning at the core.
TechTiera provides SAP BW/4HANA consulting for warehouse assessment, data modeling, data-flow integration, reporting enablement, performance optimization and support. We help organizations evaluate modernization options in the context of existing BW assets, SAC, Datasphere and wider enterprise architecture.
SAP BW/4HANA is a managed data warehouse solution optimized for SAP HANA. It is distinct from SAP S/4HANA, the ERP product. A BW modernization decision should account for source systems, transformations, historical data, authorizations, dependent reports and operational requirements.
Build a focused engagement or combine services into a wider modernization program. Scope and acceptance criteria are agreed for your environment.
Inventory existing models, transformations, process chains, sources, data volumes and reporting dependencies. Identify operational pain points and scope modernization around business requirements rather than technology replacement alone.
Design appropriate warehouse layers, Advanced DataStore Objects, CompositeProviders and queries. Document the business rules, grain, history requirements and performance expectations that shape the model and its consumption.
Plan supported source connections, extraction and load patterns. Define deltas, error handling, reconciliation and recovery so that data pipelines can be operated reliably by an accountable support team.
Assess the source release and target prerequisites, incompatible objects, custom code and downstream impact. Select an appropriate transition approach, then plan test cycles and controlled release around data and reporting continuity.
Connect the warehouse to appropriate SAC, BusinessObjects and other approved consumers. Review query design, data flows and bottlenecks, validating performance changes against representative workloads and consistent business results.
Address monitoring, load failures, incident handling and change management. Evaluate coexistence with Datasphere and the role of SAP Business Data Cloud using current product guidance, commercial boundaries and the needs of your landscape.
Confirm source release, simplification requirements, customizations and downstream dependencies.
Define history, reconciliation, delta initialization, recovery and cutover acceptance.
Compare reuse, extension and transition options against functional fit and operating cost.
A potential engagement pattern to help frame your requirements.
An enterprise wants to improve warehouse operations while maintaining trusted management reporting.
Map data flows and consumers, prioritize model remediation and validate representative queries and data loads before changing the production landscape.
A dependency inventory, target design, reconciliation baseline and migration test plan.
Every engagement should leave you with more than a configured platform. Agree the deliverables, decisions and evidence that make the work usable.
Identify business decisions, users, data sources, reports, models and operational dependencies. Agree the problem and the scope before selecting the solution.
Landscape and dependency mapCompare fit, constraints and delivery options. Define the target architecture, work packages, acceptance criteria and responsibilities.
Prioritized roadmap and scopeImplement in manageable releases. Reconcile business results, test access and performance, and record exceptions with business owners.
Test evidence and accepted releaseDocument the solution, transfer knowledge and transition into an agreed support model. Improve the landscape as business needs evolve.
Runbook and support handoverPractical guidance for your next SAP analytics decision.
A scoped engagement can include assessment, architecture, modeling, integration, migration planning, query optimization, testing and support transition. The specific activities depend on your installed release, data sources and reporting dependencies.
BW/4HANA is a data warehouse product. S/4HANA is an ERP product. They can be part of the same enterprise landscape, but migrating one does not automatically modernize the models, reports or operating processes of the other.
There is no universal answer. Existing models, history, controls and reporting dependencies may justify reuse or coexistence. We assess fit, supported transition options, operating responsibilities and the business case for a staged roadmap.
Supported SAP connectivity can enable these consumption scenarios. We assess your source queries, versions, access requirements and reporting use cases, then validate the relevant connection and feature combination.
We build a dependency inventory, identify incompatible objects and agree data and report reconciliation criteria. Rehearsals, controlled delta handling, representative testing, business sign-off and a documented rollback or recovery approach are central to the release plan.
Support can include load monitoring, process-chain failures, incident analysis, performance review and controlled enhancements. Coverage, responsibilities, interfaces and service targets are agreed for the specific environment.
