Transfer Orders in Multi-Site, unbalanced GL

Having a little bit of trouble understanding Transfer Orders in Multi-site.

I’ve setup the sites, their warehouses & bins, part plants, and transfer definitions.

During testing, I created a Transfer Order, and a Transfer Order Shipment. Then I ran the WIP Recon report to see what was happening. To my surprise I ended up with unbalanced GL transactions.

The WIP Recon (run for all sites) showed the STK-PLT transaction Crediting the Inventory account of the Site the inventory was shipped from, but no offsetting Debit

The PLT-STK transaction didn’t show up until I did the TO Receipt. This kind of makes sense, But having an unbalanced GL for the duration of the in-transit time, will not fly with accounting.

Did I miss setting up an account to hold the value while it is in transit?

I found the problem. I hadn’t set up GL Controls for type 'Plant Transfer ’
