SAC QRC4 2026 regression test guide: a repeatable QRC upgrade test plan

A quarterly release cadence is a gift for staying current and a risk for stability. The way to get the upside without the downside is a regression test plan you run the same way every quarter. This guide uses QRC4 2026 (14-15 November) as the worked example, but the plan is reusable for every QRC. For the quick per-release run-through, use the QRC4 testing checklist; for dates and scope, see the QRC4 2026 hub.

Understand the upgrade model first

SAP Analytics Cloud follows a Quarterly Release Cycle: one major update per quarter (February, May, August, November), with lighter patches in between. The release reaches a non-production test edition tenant before it reaches production, which is the window your regression plan is built around. Know your two dates - test tenant availability and production update - and schedule the plan between them.

Build the plan once, reuse it every quarter

1. Scope by criticality. List your business-critical stories, models and planning processes. You regression-test these, not the entire tenant.
2. Define expected results. For each item, record a baseline before the release: key figures, a sample allocation result, a data action output, a rendered dashboard. The baseline is what "no regression" means.
3. Weight the high-risk areas (below) more heavily than static reporting.
4. Assign owners and a sign-off. Each area has a named tester and a pass/fail record.
5. Decide the go/no-go. What must pass before you let the production update proceed, and who signs it off.

Where regressions usually hide

Weight these areas - they change behaviour across upgrades more often than plain reporting does:

• Custom scripting and analytic applications - script APIs and behaviours can shift; re-run key interactions end to end.
• Advanced formulas and calculated measures - verify results, not just that the story opens.
• Data actions, multi actions and allocations - compare outputs to the baseline value by value.
• Migrated tables and charts - the Optimized Design Experience can render or paginate differently.
• Live connections - latency, row counts and hierarchy resolution against S/4HANA, BW/4HANA or Datasphere.
• Planning versions and write-back - entry, spreading and publish across Actual, Budget and Forecast.

Mitigation and rollback

Regression testing is only useful if you can act on a failure. Agree in advance what happens if a critical check fails: delay non-essential broadcasts, communicate to affected users, log the issue with SAP against the What's New reference, and keep the previous quarter's exports so you can demonstrate the change. Reducing the surface that can break also helps - stories built from maintained templates are kept aligned with the current release, so there is less bespoke logic to regress.

Turn it into a routine

After two or three cycles the plan is muscle memory: baseline, run the checklist against the high-risk areas, sign off, go. QRC4 2026 is a good one to start with - it is the last release of the year, so a clean sign-off carries you into 2027.
