Help needed Regarding a business logic

[Former Member]

Hi all,

My business requirement is

-

---

requires to get a checksum from the KIOSK field. This would be something like a rule that for a given KIOSK generates a number from 0 to 9.

-

---

The Field value contains alphanumerical

Can any of guys help me in this logic.how to generate a checksum for a given field..

Thanks & Regards;

Maybe you ask at first your customer, what check sum algorithm should be used?

Hi,

requires to get a checksum from the KIOSK field. This would be something like a rule that for a given KIOSK generates a number from 0 to 9. 

What do you mean by checksum?

Do you want to generate a serial number like 1,2,3......?

If yes, then you can use 'index' function in the mapping.

But it would be better if you can clarify your requirement a bit more.

Hi Supriya,

There are different files with several kiosk values coming from the input side n we want to generate a checksum value so that the files with equal kiosk value should enter one process of BPM ..

Like we need to generate a number from 0-9 from the KIOSK value so files containing the same num enters the BPM process

Hi,

You can make use of 'Correlation' in BPM, so that the files with equal KIOSK values will enter one instance of BPM.

Yeah i am proposing that supriya.But they are insistent on implementing their design

Any Idea For my Reqrmnt above please?

How will you generate a number from KIOSK value . I believe KIOSK is a field , correct me if I am wrong .

You need to generate a number from KIOSK value , So there must be some business logic in number generation like whether

you need to get a substring out of total value of KIOSK field , or you need the first character or middle character .

So please provide this business transformation rule to get this more clear .

After this is done , by implementing BPM you can achieve what you want

Alright I found something I am not sure if it is of use to you , A checksum is generally used to detect the integrity of file

it is calculated oin basis of hash algorithms so how it is useful to for incoming filed values i m not sure

Please find the links below

If it is useful , you need to implement a hash algorithm
