create range table from single values

[JozsefSzikszai]

hi all,

I have a number (several thousands) of single values. I want to create a range table from these single values (as you can see there are gaps in the numbers). What is the best way to achieve that?

Values I have (in an internal table):

1

2

3

5

6

9

12

13

14

15

20

...

should be converted to:

I BT 1 3

I BT 5 6

I BT 9 9 (or I EQ 9 )

I BT 12 15

...

thanks

Suppose

Values I have (in an internal table):

1

2

3

5

6

9

12

13

14

15

20

.....

.....

values are stored in a table: IT_value and in the field fld1.

now create a range table gr_value.

Loop at IT_value into wa_values.
   gr_value-low = wa_values-fld1.
   gr_value-sign = 'I'.
   gr_value-option = 'EQ'.
   append gr_value to gr_value.
   clear: wa_values, gr_value. 
endloop.

now you can use the range table gr_value/

hi Abhishek,

your 'solution' is:

I EQ 1

I EQ 2

I EQ 3

I EQ 5

this is not what I want, pls. read the question again, before answering.

Hi,

LOOP AT itab INTO wa_itab.

l_index = sy-tabix + 1.

READ table itab into wa_itab2 INDEX l_index.

IF sy-subrc = 0.

IF <wa_itab2-f1 - wa_itab1-f1 > EQ 1.

Fill with EQ

ELSE

Fill with BT

ENDIF.

Hope you got the logic, just do some corrections.

hi Atish,

good to start from but the main thing is when and how the low and high value of the range have to be handled and when to append...

Herewith is code for reference:

  TYPES: BEGIN OF ST_NUM,
           NUM TYPE I,
         END OF ST_NUM.
  DATA: IT_NUM TYPE TABLE OF ST_NUM,
        WA_NUM LIKE LINE OF IT_NUM.

  WA_NUM-NUM = 1.
  APPEND WA_NUM TO IT_NUM.
  WA_NUM-NUM = 2.
  APPEND WA_NUM TO IT_NUM.
  WA_NUM-NUM = 3.
  APPEND WA_NUM TO IT_NUM.
  WA_NUM-NUM = 5.
  APPEND WA_NUM TO IT_NUM.
  WA_NUM-NUM = 6.
  APPEND WA_NUM TO IT_NUM.
  WA_NUM-NUM = 9.
  APPEND WA_NUM TO IT_NUM.
  WA_NUM-NUM = 12.
  APPEND WA_NUM TO IT_NUM.
  WA_NUM-NUM = 13.
  APPEND WA_NUM TO IT_NUM.
  WA_NUM-NUM = 14.
  APPEND WA_NUM TO IT_NUM.
  WA_NUM-NUM = 15.
  APPEND WA_NUM TO IT_NUM.
  WA_NUM-NUM = 20.
  APPEND WA_NUM TO IT_NUM.

  DATA: NEXT TYPE SY-TABIX,
        WA_NEXT LIKE LINE OF IT_NUM,
        WA_CURR LIKE LINE OF IT_NUM,
        DIFF TYPE I.

           SIGN(1),
           OPTION(2),
           LOW TYPE I,
           HIGH TYPE I,
         END OF SEL.
  DATA:  S_SEL TYPE TABLE OF SEL,
         WA_SEL LIKE LINE OF S_SEL,
         JUMP  TYPE SY-TABIX.

  JUMP = 1.
  LOOP AT IT_NUM INTO WA_NUM.
    CHECK JUMP EQ SY-TABIX.
    NEXT = SY-TABIX + 1.
    READ TABLE IT_NUM INTO WA_NEXT INDEX NEXT.
    IF SY-SUBRC EQ 0.
      DIFF = WA_NEXT-NUM - WA_NUM-NUM.
      IF DIFF EQ 1.
        WA_SEL-LOW = WA_NUM-NUM.
        WA_SEL-SIGN = 'I'.
        WA_SEL-OPTION = 'BT'.
        WHILE DIFF EQ 1.
          WA_CURR = WA_NEXT.
          ADD 1 TO NEXT.
          READ TABLE IT_NUM INTO WA_NEXT INDEX NEXT.
          DIFF = WA_NEXT-NUM - WA_CURR-NUM.
        ENDWHILE.
        WA_SEL-HIGH = WA_CURR-NUM.
        APPEND WA_SEL TO S_SEL.
        CLEAR WA_SEL.
        JUMP = NEXT.
      ELSE.
        WA_SEL-LOW = WA_NUM-NUM.
        WA_SEL-SIGN = 'I'.
        WA_SEL-OPTION = 'EQ'.
        APPEND WA_SEL TO S_SEL.
        CLEAR WA_SEL.
        JUMP = NEXT.
      ENDIF.
    ELSE.
      WA_SEL-LOW = WA_NUM-NUM.
      WA_SEL-SIGN = 'I'.
      WA_SEL-OPTION = 'EQ'.
      APPEND WA_SEL TO S_SEL.
      CLEAR WA_SEL.
    ENDIF.
  ENDLOOP.
