Calculating hash total

Former Member — Sat, 12 May 2007 05:04:04 GMT

Hello everyone!

I am required to produced a CSV file and the last record should have a "hash total" which works like this:

For example, we have 3 records:

Record_1: 100.02

Record_2: 101.01

Record_3: 200.15

The hash total would be calculated like this:

10002 + 10101 + 20015 = 40118

The hash total is 40118 which should be outputted as: "000000000040118"

I already tried saving the numbers into a TYPE N variable but it rounds off the decimals.

Any help will be greatly appreciated! Thanks a lot!

Hi,

Create a dataelement with type C, and domain with conversion exit(ALPHA) with required length.

Use this reference as calculated hash value.and passthis value to converion_exit_alpha_ input.you will get the leading zeros and value will not be rounded.

Hope this helps you

Regards,

decalare a varaible

data: v_num (10) type c.

first calculate the sum.

and move that sum to this field v_num.

and use the conversion fun modules

CONVERSION_EXIT_ALPHA_OUTPUT

CONVERSION_EXIT_ALPHA_INPUT

pass the same number as input and output you will get the output as '0000040118'.

Reward points if useful

Hi, Anji!

Thanks for the reply.

However, I am relatively new in ABAP so I do not know what do I need to include and how to include it to access CONVERSION_EXIT_ALPHA_OUTPUT and CONVERSION_EXIT_ALPHA_INPUT ...

Thanks for the help! ^_

data : begin of itab occurs 0,
       val(10),
       end of itab.
data : total(15).
itab-val = '100.02'.
append itab.
itab-val = '101.01'.
append itab.

itab-val = '200.15'.
append itab.

loop at itab.
replace all occurrences of '.' in itab-val with ''.
condense itab-val.
total = total + itab-val.
*modify itab.
endloop.

CALL FUNCTION 'CONVERSION_EXIT_ALPHA_INPUT'
  EXPORTING
    INPUT         = total
 IMPORTING
   OUTPUT        = total
          .

          write : / total.

Thanks a lot for your help!

I also tried another method:


  hash_total = amt_total.
  REPLACE '.' WITH '' INTO hash_total.
  CONDENSE hash_total NO-GAPS.

Where has_total is type string.

It also produces the same output I need.

Which you think is better or more efficient? Thanks!

in my reply i used the addition between two characters field but if you can avoid it then it will be better .. i think you can use your method it will be good enough...
