요구 사항
이 SDK에서 제공된 샘플 코드를 실행하기 위한 요구 사항에 대한 자세한 내용은 샘플 및 도우미 코드 사용을 참조하십시오.
보여 주기
이 샘플에서는 엔터티에 대해 사용자 지정 상태 전환이 정의되었는지 여부에 관계 없이 유효한 상태 변화를 검색하는 방법을 보여 줍니다.
샘플에서는 다음과 같은 작업을 수행합니다.
문제 엔터티에 대한 상태 옵션 검색
각 상태 옵션에 대해 유효한 상태 전환을 가져오기 위해 샘플에서 GetValidStatusOptions 메서드 사용
콘솔에 유효한 전환 옵션 표시
문제 엔터티에 대해 상태 설명 전환이 다음과 같은 방법으로 구성된 경우
.jpeg "서비스 케이스에 대한 상태 설명 전환의 예")
유효한 상태 전환이 필터링되고 다음과 같이 각 상태 옵션에 대해 유효한 모든 전환이 표시됩니다.
