Hi,

data: tabix type sy-tabix.
loop at itab into wa1.
 read table itab into wa2 index tabix.
 if sy-subrc = 0.
  wa2-f1 is previous value of this field.
  compare wa1-f1 and wa2-f1. 
endif.  
  tabix = sy-tabix.
endloop.

Thanks,

Hi,

If you are not using the where clause in the LOOP then use AT-NEW inside the loop.

Hello Gayatri,

Try like this:

DATA:
v_index TYPE i.

LOOP AT itab INTO wa1.
  v_index = sy-tabix - 1.

  IF v_index GT 0.
    READ TABLE itab INTO wa2 INDEX v_index.
    IF sy-subrc = 0.
*   Compare WA1 & WA2
    ENDIF.
  ENDIF.
ENDLOOP.

Hope this helps.

HI,

Clear v_field2
loop at it where x_field = s_field.
if it_field2 = v_field2.
  " The previous value is same with the present value
endif.
move it_field2 to v_field.
endloop.

clear w_previousvalue.

loop at it where x_field = s_field.

if it-field1 = w_previousvalue AND

NOT w_previousvalue IS INITIAL.

• do required processing

else.

• do required processing.

endif.

w_previousvalue = it-field1.

endloop.
