Summary report with two row levels: per-group subtotals, and no repeated outer value

domain:ui#3 · os-bill · session_01Utp6CaJoinvGQSbHeDaWBe

Filing gate: ③ triage-directed. The order on #27430 (rows 2–4) said: TAKE what is ui-only, CARD the rest. The card thread measured each row on origin/main ed0e71db (report 6515939841, out_of_scope_findings). Row 2 is taken in PR #27972.
Reach: any summary report with two or more rows levels. HotCRM opportunity_funnel_owner_stage as a summary (#27430 row 4).
Reader who acts: domain:ui (plugin-report), plus domain:spec only if triage chooses a declared key.
Duplicate search: search_issues "summary report subtotal per group multi-level rows repeated outer value" → no open card.

Observed

A summary report asks the server only for the grand total (totals.groupings with the empty grouping). It draws every inner row with its outer value repeated, and the spec has no subtotal key. The matrix branch already asks for row and column subtotals through totals.groupings and only places the server's pre-aggregated rows, so the server half exists.

Wanted

Triage first decides whether subtotals are the summary default for two or more rows levels, or a declared key (for example a subtotal flag on the report). If it is a key, the spec half comes first. Then the renderer asks for each rows prefix grouping, draws group header and subtotal rows, and stops repeating the outer value.

Dedupe words: summary subtotal, group subtotal, report subtotals, multi-level summary, repeated group value.

Related: #27430 (row 4).

Retriage request · 2026-10-31T05:08Z · ⛔ Not a claim.

Asked of triage: rule the card's own open question so a ui seat can take it. The card says triage first decides whether subtotals are the summary default for two or more rows levels, or a declared key. The card carries pm:queue, but no triage comment has ruled on it.

The seat leans toward the default, with no new key. A summary report with two or more rows levels would ask the server for each rows prefix grouping through totals.groupings, which the matrix branch already does. It would then draw a group header and a subtotal row per outer group, and stop repeating the outer value. That is what a summary report means as opposed to a tabular one. Under this lean, nothing an author writes changes and the renderer half is ui-only.

The cost of this lean: every existing two-level summary report starts showing subtotal rows on its next render. If triage would rather have that opt-in, the key is a spec card first, and the renderer half waits on it.

⛔ Not a claim.

Ruled as the seat leans. A summary report with two or more rows levels draws a group header and a subtotal row per outer group, with no repeated outer value. It reads the prefix groupings through totals.groupings, as the matrix branch already does. That is what a summary report means as opposed to a tabular one. No new key is added (「新增门禁默认否」 in spirit: no new surface without need), and the renderer half is ui-only.
The cost is accepted: existing two-level summary reports gain subtotal rows on their next render. The PR names it in its changeset. If the maintainer wants it opt-in instead, that comes back here as a spec card first.
It stays at p3 in pm:queue. pm:retriage removed.

Premise: holds (DatasetReportRenderer.tsx asks a summary only for the grand total on origin/main)
Serial constraints cleared: yes. The p3 hold is lifted for ui by the maintainer: 「可以开p3」, and 2026-10-31T02:39Z 「ui 车道一堆任务啊，应该并发开满啊」 in the seat thread. Other seats have not claimed this card. Outside this seat's area under the maintainer's 2026-10-31T05:10:38Z 「座位之间可以协调，你有空你就可以派」, with the area's seat asked first.

One-level summary, tabular and matrix (with or without columns) are unchanged; an answer without a prefix grouping draws the plain table. A subtotal row drills by the prefix only, with its ranges spanned over the group. Export writes the grouped table as drawn. report.subtotal added to all ten i18n packs.

reading	value
PR	merged 2026-10-31T08:57:06Z as `3ba52069` through the merge queue, on the first pass
`origin/main` content	`DatasetReportRenderer.tsx` carries `summarySubtotalPrefixes` and `nestSummaryLines`, so a summary with two or more `rows` levels asks for and draws per-group subtotals

State: Fixes #27975 closed the card as completed. pm:dispatched comes off in the same stroke as this note. Open #28305 shares DatasetReportRenderer.tsx; the merge-tree was clean, and it merges main when it lands. Groups under an order by a measure keep their first row's position. That was noted only, and would be a server card if anyone asks for it. Nothing else remains on this card.
