 * rc_ol_0029.pgc - 미매입 추출 (CURSOR) 온라인 서비스 (RC_OL_0029)
 *
 * 요청 기준일(CUTOFF, YYYYMMDD) 이하로 승인('R')되었으나 아직 매입이
 * 일어나지 않은(수수료 fee=0) 건을 커서로 순회하여 잔존 미매입 현황을
 * 추출한다. 오래된 건부터 확인하기 위해 영업일 오름차순으로 순회한다.
 *
 * 업무규칙:
 *   - 대상: status='R' AND fee=0 AND biz_date <= :cutoff
 *   - 미매입 건수 UNCAPCNT 와 금액합계 SUMAMT 누적
 *   - 가장 먼저(가장 오래된) 만난 건의 KEY 를 FIRSTKEY 로 캡처
 *
 * 응답: CUTOFF, UNCAPCNT, SUMAMT, FIRSTKEY  (읽기 전용)
