Odd problem with orders and authorize.net

[rmn]

I have 2 customers that placed orders in my store. My store is 1.38a, db is 1.38. My store is using Authorize.Net AIM. Here is the issue I've seen twice now.

By looking at my Authorize.Net stmt, I can see cust A placed an order on Jun 8, 11:31:33, which was declined. He then successfully placed the order on June 8, 11:54:21. This order was success. Cust B placed an order on Jun 8, 11:56:58, which was successful. By saying successful, I mean it was listed in the Authorize.Net settlement report.

Here's the weid thing:
Cust A's order information shows in Zencart. But Cust B's sold to information ended up in Cust A's order. The order id's were 1596 and 1598. Both orders were for the exact amount, but different items.

The authorize.Net statement invoice number column for both customers shows invoice number 1598.

Any help is much appreciated.

Thank you,
Rhonda

What is the exact order number that shows on authorize.net?

Since v1.3.8, it should be a number followed by a hyphen and 6 random letters. This is to ensure uniqueness and prevent duplication.
If you're not seeing those additional letters in authorize.net then it suggests to me that you're using an older AIM module.

Invoice Number on Authorize.Net
1598-l2lq9l
1598-Lfvf0F

Looks like the newer AIM?

Were the times you mentioned from Zen Cart admin, or from authorize.net?
Can you provide both sets of times for both orders?

Unfortunately, my customer deleted the order the order that was the duplicate looking order that had the cust b's information in the sold to. The times I gave were from authorize.net.

Who assigns the extra 6 letters to the order # - Authorize.net or Zen Cart?

The reason I ask is that those extra letters make it dificult to match Zen Cart orders with Authorize.net reports. For instance, if we want to issue a refund, and input the Zen Cart order # to authorize.net's search box, it doesn't find the order!

Any ideas on how we can solve this problem? Thanks!
