If they have the same structure:


IF it_1[] = it_2[].
   " Tables contents are the same
ELSE.
   " Tables contents are different
ENDIF.

If they have different structure, you probably must loop one of the tables, and inside read the other, then compare field by field.

Or if you don't need the contents (just comparing) you can do this, for example:


LOOP AT it_1 INTO wa_1.
   READ TABLE it_2 WITH KEY field2 = wa_1-field2
                            field5 = wa_1-field5
                   TRANSPORTING NO FIELDS.
   IF sy-subrc = 0.
      " Record is on both tables (field2 and field5 are the fields in common for both tables).
   ENDIF.
ENDLOOP.

Regards.

Hi K K,

I think we can not compare the internal table if their structure is diffrent but i think we can compare the internal table fields whic is common in both the internal tables.

If IT_tab-field = IT_tab1-field.

business logic.

endif.

if helpfull reward points.
