access next element inside the loop

[Former Member]

Hello Friends,

I would like to know if its possible to access the next comming element inside the loop as we have in java, FOR loop ++ or +1 stuff.

Actually I have to create dynamic selection ( fields- name, sign, value, I have in an internal table) and inside the where clause I have to put 'AND' or 'OR' depending upon if field is same or change....if the field is same I have to use OR and if field changes I have to use AND.

Many thanks for your kind inputs,

Regards,

So I just have to see the next field inside the loop, if next is same, I will place OR at the end of previous statement, and if next comming field is different I have to place AND at the end of previous statement.

• now the work area wa will have the next record.

Hi ,

Use this.

  DATA : l_index TYPE sy-tabix.

  LOOP AT t_marc INTO wa_marc.
    l_index = sy-tabix + 1.
    READ TABLE t_mara INTO wa_mara read table itab INDEX l_index.

"Some Processing

    CLEAR l_index. 
  ENDLOOP.

Hi,

Use sy-tabix+1 for internal table and

sy-index+1 for do loop.

loop at itab.

lv_index = sy-tabix.

lv_index = lv_index + 1.

read table itab index lv_index.

if sy-subrc eq 0.

endif.

endloop.

Hi

If index + 1 does not exist then it will return

SY_SUBRC <> 0

i.e

SY-SUBRC = 4

hi Shah,

Declare a local variable that holds sy-tabix value.

data : lv_tabix type sy-tabix.

loop at itab.

*Increase the value by 1.

lv_tabix = sy-tabix + 1.

read table itab into wa index lv_tabix.

• now the work area wa will have the next record.

**//here you can do your processing.

endloop.

Hope this will help you.

Hi Shah,

first get the value of sy-tabix in a local variable i.e.

l_index.

loop at t_itab.

l_index = sy-tabix.

l_index = l_index + 1.

read table t_itab index l_index.

endloop.

hope this works for u.
