SAP IBP HPA – Seven Questions, Seven Answers

Over the past few years, CONSILIO has implemented SAP IBP for customers across various industries. Since then, planners have been working with ease and processes have been running smoothly. Suddenly, SAP has introduced the term HPA (Harmonized Planning Area), and many customers are wondering: Will my system soon be “outdated”? Do I have to migrate again? Was all that work for nothing?

This blog post addresses these concerns. Seven answers to the most important questions customers have raised in conversations—honest, practical, and without sugarcoating.

HPA is the new “unified planning domain” in SAP IBP. Previously, there were two separate worlds:

• Time-series-based planning (demand planning, S&OP, inventory optimization)
• Order-based planning (supply planning, response management, deployment planning)

The HPA merges these two worlds into a single planning area with a unified data model and unified master data, thereby eliminating gaps between the different processes.

The answer to that is a clear “no.” As of May 2026, SAP is not requiring any migration. The traditional planning modules will continue to operate as usual, receive updates, and be fully supported by SAP. SAP currently recommends HPA primarily for new customers and future IBP projects.

For existing customers, migration is still a time-consuming process, as it must currently be done manually. The reason: There are structural differences between the old and new systems in terms of key metrics, master data, and planning structures.

However, SAP has announced that it will make migration tools available starting in mid-2026, which are intended to greatly simplify the transition and partially automate it. Until these tools are available and tested, CONSILIO advises against migration for cost-benefit reasons.

The key benefits for companies using IBP with HPA:

• Less data redundancy (data needs to be maintained only once)
• End-to-end transparency (from the forecast to, for example, the planned order within a division)
• Standardized integration (real-time integration for master and order data from S/4HANA on-premise/private cloud; cloud integration for additional data and systems)  
• Reduced administrative effort in the long term
• New features (especially AI and advanced planning logic) are released first—or in some cases exclusively—for HPA

Here, too, the answer is a clear “no.” Anyone already using IBP can switch to HPA without incurring additional licensing costs. It offers the same feature set, but with a modernized technical foundation.

As mentioned earlier, the optimal time is expected to be in Q3/Q4 2026, once the official migration tools are available and stable.

An earlier switch is only worthwhile if a company needs specific new features that are available exclusively in HPA or work significantly better there. These include, among others, the following requirements:

• Harmonized scenarios: What-if analyses in which changes to master data, key metrics, and orders can be simulated simultaneously
• Advanced AI-powered features: AI-assisted scenario planning or improved demand sensing across the entire planning chain
• Hierarchical lookup of attributes in time-series-based planning: No manual data duplication (e.g., planning calendars or lot sizes) required at the source of supply level

There are no known serious consequences in the short to medium term. The current IBP system remains fully functional and will continue to receive all updates from SAP. In the long term (2028 and beyond), however, HPA will likely become SAP’s strategic standard. Those who wait too long may eventually face a complex and more expensive migration.

HPA is a sensible and important evolution of SAP IBP. It makes the system simpler, more transparent, and better prepared for the future. For most existing customers, however, the current approach is to continue working with the tried-and-true system while evaluating HPA in parallel. Once the migration tools are available, they will be able to make an informed, low-risk decision.
