 * rc_ol_0020.pgc - 부분대사 온라인 서비스 (RC_OL_0020)
 *
 * 접수건에 대해 부분매입액(PARTAMT) 을 반영하는 부분대사를 수행한다.
 *
 * [입력]
 *   KEY     - 처리키(승인/거래 번호)
 *   PARTAMT - 부분매입액(원)
 *
 * [처리 규칙]
 *   - PARTAMT 가 0 이하이거나 원장 거래금액을 초과하면 입력오류(TX_EINVAL).
 *   - PARTAMT == amount  → 전액대사 → 매입확정('M'), 잔여액 0, RESULT=FULL.
 *   - PARTAMT <  amount  → 부분대사 → 접수('R') 유지, 잔여액=amount-PARTAMT,
 *                          RESULT=PARTIAL. (남은 금액에 대한 추가 대사 필요)
 *
 * [응답]
 *   KEY / AMOUNT / PARTAMT / REMAIN(잔여액) / STATUS / RESULT
 *
 * 커서를 사용하지 않는 단건 처리 서비스이다.
