안녕하세요. Job 생성하는 아밥 프로그램을 딴 분이 짠 소스에 보면 아래와 같은 구문이 있습니다.

아래 구문중에 import , export 라는 구문이 있던데 이게 모하는 건지..ㅠ.ㅠ 

ID 다음에는 'SD0140C1' 이런걸 몰 의미하는건지 몰겠네요.. 알려주세요 ...

IMPORT ct_data FROM DATABASE  indx(s1) CLIENT sy-mandt ID 'SD0140C1'.
IMPORT lt_data FROM DATABASE  indx(s1) CLIENT sy-mandt ID 'SD0140C2'.

EXPORT ct_data TO DATABASE  indx(s2) CLIENT sy-mandt ID 'SD01401'.
EXPORT lt_data TO DATABASE  indx(s2) CLIENT sy-mandt ID 'SD01402'.
