loop at it1 into wa1.

read table it2 from wa with key field = wa-field.

if sy-subrc = 0.

append it3 to wa.

endif.

endloop.

[kiran_k8]

IF itab1[] = itab2[].

" Tables contents are the same

ELSE.

" Tables contents are different

ENDIF.

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

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

LOOP AT itab1 INTO waitab1.

READ TABLE itab2 WITH KEY field2 = waitab1-field2

field5 = waitab1-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.

As far as deletion is concerened you can follow the below given logic.

loop at itab.

v_tabix = sy-tabix.

read table itab2 with key <<<key field >> = itab-<<<key field>>

if sy-subrc eq 0

flag = 'X'.

modify itab.

endif.

endloop.
