+# 재원협의(fnrs-cnsltn) vs 설치인가(instl-sncn) 차이 분석

+| 작성일    | 2026-07-09                                                                    |
+| 기준 구현 | `fnrs-cnsltn` (추가 요구사항 반영 완료)                                       |
+| 비교 대상 | `instl-sncn`                                                                  |
+| 목적      | 두 페이지의 동작·구조 차이를 정리하고, 설치인가 정렬 시 이식 대상을 명확히 함 |
+
+---
+
+## 1. 요약
+
+두 모듈은 **동일한 PBADMS(공공행정 지원) 업무 패턴**을 따르는 형제 페이지다.
+
+공통 흐름:
+
+```
+목록 → TaskSe 선택 후 신청 → 저장(SV) → 신청완료(ST)
+  → 환경청제출(LE) → 기술검토 → 검토결과 회신(EP)
+  → 인가승인(TA) → 고시(TB)
+```
+
+| 구분          | fnrs-cnsltn       | instl-sncn       |
+| ------------- | ----------------- | ---------------- |
+| 업무명        | 재원협의          | 설치인가         |
+| 문서번호      | `fnrsCnsltnDocNo` | `instlSncnDocNo` |
+| docSeComCd    | `FNRS`            | `INSTL`          |
+| 라우트        | `/fnrs-cnsltn/*`  | `/instl-sncn/*`  |
+| pages 파일 수 | 39                | 32               |
+
+**결론:** `fnrs-cnsltn`이 추가 요구사항이 반영된 기준(reference) 구현이고, `instl-sncn`은 동일 골격이지만 보완요청·결재선 편집·등록/수정 폼 완성도 등에서 미반영·TODO·단순화 상태다.
+
+---
+
+## 2. 파일/폴더 구조
+
+### 2-1. fnrs-cnsltn에만 존재
+
+| 경로                                         | 역할                      |
+| -------------------------------------------- | ------------------------- |
+| `ui/sections/fnrs-shar-section.tsx`          | 재원분담 조회 섹션        |
+| `ui/sections/supplement-demand-section.tsx`  | 보완요청 이력 섹션        |
+| `ui/components/sortable-prgrs-stts-row.tsx`  | 결재선 DnD 편집 행        |
+| `ui/components/sortable-apln-picker-row.tsx` | 결재선 템플릿 피커 DnD 행 |
+| `ui/components/aprvr-picker-dialog.tsx`      | 결재자 선택 다이얼로그    |
+| `ui/components/elapr-apln-picker-grid.tsx`   | 결재선 편집 그리드        |
+| `ui/components/elapr-tmplt-select-table.tsx` | 결재서식 선택 테이블      |
+| `model/reviewer-option.ts`                   | 결재자 옵션 타입          |
+
+### 2-2. instl-sncn에만 존재
+
+| 경로                                   | 역할                | 비고                                       |
+| -------------------------------------- | ------------------- | ------------------------------------------ |
+| `ui/sections/history-info-section.tsx` | 등록/수정 이력 표시 | **어디에서도 import되지 않음 (dead code)** |
+
+### 2-3. 공통 구조
+
+```
+index.ts
+ui/
+  {list,view,form,regist,edit}-page.tsx
+  sections/  (basic-info, contact, scale, cost, checklist, attachments, tech-review)
+  components/ (floating-action-buttons, elapr-approval-dialog, elapr-tmplt-picker-dialog, checklist-task-panel)
+lib/   button-config, save-payload-utils, form-data-mapper, regist-schema, checklist/review utils
+model/ columns.tsx, view-types.ts
+```
+
+App Router도 동일: `page.tsx`, `regist/page.tsx`, `[id]/page.tsx`, `[id]/edit/page.tsx`
+
+---
+
+## 3. 목록 페이지
+
+### 3-1. 검색 필터
+
+| 항목               | fnrs-cnsltn                               | instl-sncn                        |
+| ------------------ | ----------------------------------------- | --------------------------------- |
+| 시도/시군구 API    | `@/entities/adstdstr`                     | 동일                              |
+| 지역 검색 파라미터 | **`admdstCd`** (시군구 우선, 없으면 시도) | **`sidoComCd` + `sggComCd`** 분리 |
+| "전체" 옵션        | `ALL_SELECT_VALUE = "__ALL__"` SelectItem | 없음 (placeholder만)              |
+| 구분 CodeSelect    | `upCd="INSTL"` ※                          | `upCd="INSTL"`                    |
+| 사업명             | 동일                                      | 동일                              |
+
+> ※ fnrs 목록의 구분 필터가 `INSTL` 코드를 사용 중이며, TaskSePickerDialog는 `codeUpCd="FNRS"`를 쓴다. **불일치 가능성**이 있어 확인이 필요하다.
+
+### 3-2. 정렬·페이지네이션
+
+| 항목                     | fnrs-cnsltn            | instl-sncn                            |
+| ------------------------ | ---------------------- | ------------------------------------- |
+| 기본 sort (list-page)    | `fnrsCnsltnDocNo,desc` | `instlSncnDocNo,desc`                 |
+| fallback sort (list.tsx) | `fnrsCnsltnDocNo,desc` | **`regDt,desc`** (list-page와 불일치) |
+| 페이지 크기              | 10                     | 10                                    |
+| URL 동기화               | 없음 (`useState` 로컬) | 없음                                  |
+
+### 3-3. 테이블 컬럼
+
+`model/columns.tsx` 로직은 사실상 동일하다. DTO 타입명만 다르다.
+
+컬럼: 시도, 시군구, 사업명, 업무구분, 담당자, 해당기관, 진행상황, 신청일
+
+### 3-4. 행 클릭·신청
+
+| 항목         | fnrs-cnsltn                                                        | instl-sncn         |
+| ------------ | ------------------------------------------------------------------ | ------------------ |
+| 행 클릭      | **조건부 라우팅**: `SV`/`SL` + 등록자 본인 → `/edit`, 그 외 → view | **항상 view**      |
+| useUserStore | 사용                                                               | 미사용             |
+| 신청 버튼    | TaskSePickerDialog `codeUpCd="FNRS"`                               | `codeUpCd="INSTL"` |
+
+```46:54:apps/as/src/pages/fnrs-cnsltn/ui/fnrs-list.tsx
+  const handleRowClick = (row: FnrsCnsltnMngResponseDto) => {
+    const canEdit =

+      row.rgtr === userInfo?.userUnqId;
+
+    router.push(

+## 9. fnrs-cnsltn에만 있는 기능 (추가 요구사항 후보)
+
+instl-sncn 정렬 시 **우선 이식 대상**:
+
+1. 목록 행 클릭 조건부 edit 라우팅 (`SV`/`SL` + 등록자)
+2. 보완요청 전체 플로우 — view 섹션, payload builder, API, FAB handler
+3. 보완완료 API 연동 (`submitSupplement`)
+4. 등록/수정 폼 완성 — 신청완료, 삭제, 저장 후 edit 유지
+5. 결재선 DnD 편집형 `ElaprApprovalDialog` (+ aprvr-picker, sortable rows)
+6. 결재선 편집형 `ElaprTmpltPickerDialog` (+ apln grid, validation)
+7. 검토완료 → 결재 다이얼로그 연계 흐름
+8. 검색 필터 "전체" 옵션 및 `admdstCd` 통합 방식 (백엔드 API에 맞게)
+9. Edit 페이지 로딩 Skeleton
+10. entity에 supplement API/hooks 추가
+
+---
+
+## 10. instl-sncn에만 있는 기능 (유지 필요)
+
+1. **`sncnSeComCd` (사업구분/인가구분)** — 도메인 고유
+2. **`bgtBizCd` / `bgtAplyYr`** BnsPicker 연동
+3. **`history-info-section.tsx`** — 구현만 있고 view 미연결 (활성화 또는 삭제 결정 필요)
+4. entity **`instlSncnRegionService`** — 목록은 adstdstr 사용 중이라 중복/레거시 가능
+5. **`INSTL_SNCN_REGISTER_SELECTION_KEY`** sessionStorage 키
