在ABAP中找到两个数据集的差异？

DATA: lt_dataset1 TYPE TABLE OF string,
      lt_dataset2 TYPE TABLE OF string,
      lt_difference TYPE TABLE OF string.

APPEND 'Data1' TO lt_dataset1.
APPEND 'Data2' TO lt_dataset1.

IF lt_difference IS NOT INITIAL.
  WRITE: 'The differences between the two datasets are:'.

    WRITE: / ls_difference.
  ENDLOOP.
ELSE.
  WRITE: 'No differences found between the two datasets.'.
ENDIF.
