内表之间赋值

1. 循环拷贝

   1 LOOP AT IT_A .
   2     IT_B-xxx = IT_A-xxx .
   3     ...
   4     APPEND IT_B .
   5     CLEAR IT_B .
   6 ENDLOOP .

    

2. 根据内表IT_A修改内表IT_B
   

   1 LOOP AT IT_B .
   2     READ IT_A WITH KEY xxx = IT_B-xxx .
   3     IF SY-SUBRC = 0 .
   4         IT_B-... = IT_A-... .
   5         .....
   6     ENDIF .
   7     MODIFY IT_B COMPARING .... .
   8 ENDLOOP .

    

3. 直接拷贝

   1 APPEND LINES OF IT_A TO IT_B .

    

4. 直接给内表赋值

   1 IT_B[] = IT_A[] .
