calculation of container check digit

Former Member

Dearest All.

i hv a requirement .. i hv to calculate check digit for Conatiners for Export and Import.

i tried a lot but failed.....

the logic is as follow...

Every container-number needs its own check digit. This check digit is the last figure of the container-number, that behind the -.

Of course, you can calculate this check digit yourself.

First start with the prefix. Then there is the number itself.

This is the simplest part of the calculation. Last but not least the calculation:

with an example: OOLU 708695.

Each letter of the prefix has its own value:

A 10 J 20 S 30

B 12 K 21 T 31

C 13 L 23 U 32

D 14 M 24 V 34

E 15 N 25 W 35

F 16 O 26 X 36

G 17 P 27 Y 37

H 18 Q 28 Z 38

I 19 R 29

Each figure of the number has its own value.

1 1

2 2

3 3

4 4

5 5

6 6

7 7

8 8

9 9

0 0

We know that: Now calculate:

O 26 26 X 1 = 26

O 26 26 X 2 = 52

L 23 23 X 4 = 92

U 32 32 X 8 = 256

7 7 7 X 16 = 112

0 0 0 X 32 = 0

8 8 8 X 64 = 512

6 6 6 X 128 = 768

9 9 9 X 256 = 2304

5 5 5 X 512 = 2560

________________________________________

Total = 6682

Of course we can understand if you don't want to calculate all these check digits by hand.

Therefore we made you a little tool.

Enter the container-number as followed: XXXX123456, just try it.

Container-number:

Check digit:

Calculate the check digit Clear the form

Now divide this total by 11:

6682 / 11 = 607,4545

and take the figures after the comma

and multiply it by 11 to get the check digit.

0,4545 X 11 = 5

The complete container-number is:

OOLU 708695-5

hi ,

O 26 26 X 1 = 26
O 26 26 X 2 = 52
L 23 23 X 4 = 92
U 32 32 X 8 = 256
7 7 7 X 16 = 112
0 0 0 X 32 = 0
8 8 8 X 64 = 512
6 6 6 X 128 = 768
9 9 9 X 256 = 2304
5 5 5 X 512 = 2560
________________________________________ 
Total = 6682

will you explain this why you have taken " 26X1 ,26X2 ,23X4 ,32X8 i.e multiplied with 1,2,4,8

This is the requirement given by user to calculate the check digit for tracking the rite container..

the user will enter the digit ( Container no) on the screen like OOLU 708695. and OOLU 708695- 5 with come automatically.

i m not getting anyway where to start writing code...

HEY ,

don't get panic

you can do this

go step by step

if you are aware of Dialog programing then you can do this

OR if you want to do in simple basic report then also it is possible just use your logic .

1) create one module pool

2) create one screen

in screen give one button to get EVENT in PAI

in PAI you can write code

now for

albhabets and there numbers you can ceate either one ztable or you can create one internal table with cloumn

albhabet , value

A 20

B 30

etc

also same for

1 ,1

2,2

3,3

etc

when user will enter this number say OOLT 78432

use spilt function to split the entered string into two string

check the length of BOTH string

using DESCRIBE FUNCTION

NOW UP TO THAT LENGTH

IF LENGHT OF 1ST STRING IS 4

AND LENGTH OF SECOND IS 5

THEN

for 1st character check with albhabet value

get 1st value and multiply with 1

get 2nd and multiply with 2 .

get 3rd and multy with 4 .

and so on .

same for numbers

you can do and

use you logic for other steps

you can do that .

just go step by step how you have explained .

Deepak.
