Internal table using collect

[Former Member]

Hi,

I have some problem in internal table using collect.

thatis

it1-1 it-2 it-3 it-4(Count of it-2)

1 Nan 30 2

2 Rav 40 1

3 Ram 20 1

4 Raj 20 1

5 Nan 10 2

this is my internal table.

here it-4 is no.of time repeated counted through loop.

Now i am giving collect means no.of time repeated will show all '1' only not no.of times repeated. here i want to count before display and before collect.1 ,2 and 3 fields are collected from database field 4 generated dynamically.

or else i want to copy same fields to another it means field 4 last line count only showing otherslines are displaying 0's

What i can do?.

Thanks

Nandha,

Keep in the mind that it1 it2 should be of non-numneric fields.

Is that it3 and it4 are numeric ???

so Using COLLECT will add values in it3 and it4 making single row for Nan eg : .

Rav 40 1

Ram 20 1

Raj 20 1

Nan <b>40 4</b>

Thanks

Hi,

This is ok but i don't want to sum 4th column.4th column value is the count of third column

i.e nan tow times repeated means it'll show 2

that 2 i need without changes

Thanks

Hi Nandha,

Can you please give somemore information with a clear example? Please correct me if I am wrong.

You have an internal table ITAB with 4 fields, let us say A, B, C and D. You gave us the values of the internal table as follows

A   B  C
1  Nan 30
2  Rav 40
3  Ram 20
4  Raj 20
5  Nan 10

Now you want to know how many times a value in column B is repeated and have that to be in your 4th column D. I don't think you can achieve that using COLLECT. You have to do it in a loop and by sorting your ITAB. Try this.

SORT itab BY b.
LOOP AT itab.
  IF v_previous_b_value = itab-b.
*-- the value in column B hasn't changed, increment the count
    b_count = b_count + 1.
  ELSE.
*-- it is a new B value, modify the internal table
*   with previous B value count
    IF sy-tabix = 1.
*-- this is the first record, do not do the update
      b_count = 1.
    ELSE.
      itab-d = b_count.
      MODIFY itab TRANSPORTING b_count WHERE b = v_previous_b_value.
      b_count = 1.
    ENDIF.
  ENDIF.
  v_previous_b_value = itab-b.
ENDLOOP.
*-- for the last record
itab-d = b_count.
MODIFY itab TRANSPORTING b_count WHERE b = v_previous_b_value.

I am just typing this out directly without testing, but I think you will get the idea.

If the first field in numeric then use of collect would result in

2 Rav 40 1

3 Ram 20 1

4 Raj 20 1

6 Nan 40 4

If it is non-numeric,

then, this will result

1 Nan 30 2

2 Rav 40 1

3 Ram 20 1

4 Raj 20 1

5 Nan 10 2
