retrieval reference number

[extreme logic]

Hello,

How do I automatically generate a RRN (retrieval reference number) in
JPOS?

Thanks in advance.

The RRN is just a string of up to 12 characters that uniquely identifies
a transaction. If you're storing your transactions in a database, then
you could use some database generated identifier, such as your
transaction's 'id'.

Sometimes nothing at all, sometimes there are rules about ensuring
uniqueness across a time period.

They key is to work out who defines the need (if any) on the interface
you wish to connect with...

... they will know the rules to which you should comply.
