Give me your email address, and I'll send it to you. You can send me an email at olie480(at)gmail(dot)com make sure the title of the email reads HEADQUARTERS, since this is my spam inbox, and I don't have to fish through a bunch of emails to find it.
Global Customers can be done, I think the only thing you would have to do is actually goto into the backend of the SQL server (using SQL Management Studio Express) and run this script.
UPDATE dbo.Customer SET GlobalCustomer = 'true';
After this is done, you'll want to send a Worksheet 401 to download those new customers into HQ.
If you have an IT department, then hopefully one of them knows SQL, and they can manipulate data into headquarters.
We actually came from using Comcash about 2 years ago, so that was a mess transfering data from that database to the new one, I use EMS SQL Manager to do it, but it was A LOT of exporting to CSV and mapping the correct columns in RMS. Aye, it was a mess, but since you're already on a RMS platform, it shouldn't be too hard, since the DB's from RMS and HEADQUARTERS reflect the same, except for a few columns that headquarters uses.
Also note, if you are going to create a new store through the headquarters template process, and if you're running Hero Points, you'll have to delete some of their tables from the database, and when you run the Hero Points installer, they will just be recreated. That's the only problem I had when setting up a template store, but it was resolved after deleting those.
Hope this helps!
