Duplicating IAN

Hi Guys,

I've finished my tests of our new COA and just before moving it to
production I decided to re-check the configuration and test some more
postings.

I've found that our system is duplicating IAN's for many of our records and
is posting in multiple accounts. What I've done was that I loaded the new
segments for my new COA (using transfer-to) in a test environment bu when
the system created the IANs for the new combinations, it started in the
middle of the list, instead of continuing from the last number. Do you guys
know why that happened ?

I'm kind of desperate since I have to move this to production in 2 days and
I don't feel comfortable to do so with this problem !

Any help is much appreciated !

Best regards !

Rony
