[4주차 메인과제] 서브 토탈 구현 및 ALV 출력

목표: 특정 출력 필드를 포함한 ALV 출력 (서브 토탈 및 옵션/정렬 조건 포함)

 

SPFLI 테이블

 

• 출력 필드:
  • CARRID: key필드
  • CONNID: key필드
  • PRICE: do_sum = 'X'. 조건
  • CURRENCY: emphasize 옵션
  • PLANETYPE: emphasize 옵션
  • 정렬 조건 추가
  • 서브토탈 구현하기 
    • CARRID: sub_tot up
    • CONNID: sub_tot up
