What this article delivers

  • CPEA is the credit pool. Cloud Platform Enterprise Agreement runs a pre paid credit balance.
  • BTPEA is the subscription. BTP Enterprise Agreement runs fixed subscriptions to named services.
  • Capacity units differ by service. Each BTP service has a published capacity unit conversion ratio.
  • Credits expire annually. CPEA credits do not roll forward by default.
  • Service catalog moves. SAP adds and removes services across the catalog each quarter.
  • Free tier is free of charge. Some BTP services carry a free tier that does not draw down credits.
  • Vendor Shield holds the floor. Independent advisory runs the conversion math and the renewal moves.

SAP Business Technology Platform sells under two commercial models. CPEA is a pre paid credit pool. BTPEA is a fixed subscription to named services. Both models meter consumption in capacity units.

The conversion ratio between credits and capacity units varies by service. The buyer side that maps the conversion at signature avoids the year end write off.

CPEA versus subscription

SAP BTP runs under two commercial models. The buyer side that picks the wrong model at signature overpays for the full term.

Cloud Platform Enterprise Agreement

CPEA is a pre paid credit pool model. The customer commits a dollar amount per year and the credit pool refills annually. Any BTP service draws from the pool.

BTP Enterprise Agreement

BTPEA is a fixed subscription model. The customer subscribes to specific BTP services at fixed capacities. The subscriptions renew on a fixed cycle.

The hybrid path

A hybrid customer holds CPEA for variable workloads and BTPEA for stable production workloads. The hybrid lowers the over commit risk on CPEA while preserving the discount on BTPEA.

The capacity unit math

Capacity units are the SAP metric for BTP service consumption. Each service publishes a capacity unit conversion ratio. The buyer side that reads the ratio holds the consumption forecast.

The capacity unit definition

A capacity unit is an abstract unit of service consumption. SAP Integration Suite messages, SAP HANA Cloud memory, and SAP Build Apps users all convert to capacity units at different ratios.

The published conversion table

SAP publishes the conversion table by service in the BTP service catalog. The table updates quarterly. The buyer side reads the table at every renewal.

The free tier rule

A small subset of BTP services carries a free tier. The free tier consumption does not draw down credits. Misclassifying free tier consumption inflates the forecast.

  • Read the conversion table. Pull the current capacity unit ratio for every active service.
  • Map service to consumption. Project the annual consumption in capacity units, not credits.
  • Apply the free tier. Subtract the free tier allotment from the forecast.
  • Validate against the prior year. Compare projection to the trailing twelve months of actual consumption.

Service conversion ratios

Different BTP services convert capacity units at very different rates. The buyer side that does not normalize the ratio compares unequal services against the same credit pool.

Integration and event services

SAP Integration Suite and the Event Mesh convert capacity units by message volume. The ratio is steep above the published tier.

Database and analytics services

SAP HANA Cloud and SAP Datasphere convert capacity units by memory size and compute hours. The conversion compounds when both metrics scale together.

Application and AI services

SAP Build Apps, SAP Build Process Automation, and the SAP Joule AI services convert capacity units by named user or runtime hours.

Expiry and rollover terms

CPEA credits expire annually by default. The buyer side that does not negotiate a rollover clause writes off the unused balance.

The default expiry

The default CPEA term carries no rollover. Unused credits at the end of the annual term are written off. The customer enters the next year with a fresh pool.

The negotiated rollover

A rollover clause moves unused credits to the next year. The achieved rollover ratio is between twenty and one hundred percent in negotiated deals.

The mid term true up

Crossing the annual commit triggers a true up. The true up applies the list rate to the over consumption unless the order document names a different overage rate.

Consumption visibility

SAP BTP provides consumption telemetry through the BTP Cockpit and the SAP for Me commercial portal. The buyer side that reads consumption monthly holds the renewal floor.

The BTP Cockpit

The BTP Cockpit shows capacity unit consumption by service. The cockpit also shows free tier usage separately from billable usage.

The SAP for Me portal

SAP for Me shows the commercial view. The customer sees committed credits, consumed credits, and the remaining balance by month.

The over commit and under commit trap

Over commit leaves a write off at year end. Under commit pushes consumption to the list rate. The right size sits inside one move of the trend line.

The renewal motion

The BTP renewal letter assumes the prior commit. The buyer side that documents lower consumption before the letter lands resets the commit.

The consumption review

Run a twelve month review by service. Identify the over commit and the under commit by service.

The conversion table refresh

SAP updates the conversion table quarterly. The renewal must read the current ratios, not the prior year ratios.

The exit clauses

The renewal is the moment to negotiate rollover, conversion, and overage clauses. The clauses sit in the order document, not the global agreement.

What to do next

The checklist takes the buyer from the BTP commercial question to the executed commitment. The earlier the work starts, the wider the option set.

  1. Pull the BTP service inventory. Identify every BTP service in use across the estate.
  2. Read the conversion table. Capture the current capacity unit ratio for each active service.
  3. Pull the consumption telemetry. Capture the trailing twelve months of consumption from the BTP Cockpit.
  4. Apply the free tier. Subtract the free tier allotment from the forecast.
  5. Pick the model. CPEA, BTPEA, or hybrid depending on workload stability.
  6. Size the commit. First year commit at demonstrated consumption, not the forecast.
  7. Negotiate the clauses. Rollover, conversion, ramp, and overage clauses sit in the order document.
  8. Run Vendor Shield review. Independent buyer side review at every gate.

Frequently asked questions

What is a capacity unit in SAP BTP?

A capacity unit is the SAP abstract metric for BTP service consumption. SAP publishes a conversion table by service that maps real consumption to capacity units. Examples include Integration Suite messages, HANA Cloud memory, and Build Apps users. Each service has a distinct conversion ratio and SAP updates the ratios quarterly.

What is the difference between CPEA and BTPEA?

CPEA is Cloud Platform Enterprise Agreement, a pre paid credit pool model where the customer commits a dollar amount and any BTP service draws from the pool. BTPEA is BTP Enterprise Agreement, a fixed subscription model where the customer subscribes to specific BTP services at fixed capacities. Many enterprises run a hybrid to manage over commit risk.

Do BTP credits roll over annually?

By default CPEA credits expire at the end of each annual term and unused credits are written off. A rollover clause negotiated at signature lets the customer carry forward unused credits to the next year. The achieved rollover ratio is between twenty and one hundred percent in negotiated deals.

How do I forecast BTP consumption?

Pull the BTP Cockpit consumption telemetry for the trailing twelve months by service. Apply the current capacity unit conversion table to project the next year. Subtract the free tier allotment. Validate the projection against the prior year actual. Independent advisory benchmarks the forecast against peer commitments before signature.

What happens when I exceed the BTP commit?

Crossing the annual commit triggers a true up. By default the true up applies the list rate to the over consumption. A negotiated overage clause in the order document can set a different rate that protects the customer at the discount band. Reading the overage clause before signature is the single largest defense move.

Which BTP services carry a free tier?

SAP publishes the free tier list in the BTP service catalog. The list changes over time. Free tier consumption does not draw down credits and is invoiced separately on the cockpit. Misclassifying free tier consumption against the credit pool inflates the consumption forecast and drives over commit at signature.

Can I convert BTP service mix during the term?

Yes under CPEA. The credit pool model lets the customer shift consumption across any BTP service without renegotiating the contract. Under BTPEA the conversion is constrained because the subscriptions name specific services. A hybrid path provides both flexibility on the CPEA side and discount on the BTPEA side.

How does Redress engage on SAP BTP?

Redress runs the pre commit consumption review, the conversion table benchmark, the order document review, and the renewal motion inside the Vendor Shield subscription and the Renewal Program. The work includes the rollover clause negotiation, the overage clause review, and the contract negotiation against peer benchmarks.

How Redress engages

Redress runs this practice inside the Vendor Shield subscription, the Renewal Program, the SAP service line, and the Software Spend Assessment.
