Manual Split does nothing

Maybe you are missing the checkbox which will make all products enabled for split check. Please confirm if you are using the default split method?

Ok, I clicked the checkbox on the ‘Order Split Settings’ screen at the top of the list of products. Is this what you mean?

After selecting, now when I do a manual split from the single order page, It just seems to be duplicating the order. The order I’m using has 2 products and both are selected.
How can I split the order so that the original order has two products, and then I create two new orders, each with a different single product?

Now you are missing the remove from parent checkbox on settings page, I believe.

Thanks for the quick reply.
It looks like remove from parent is not really what I want.
I still want the parent to look exactly as it originally did.
If an order has 2 items I want to split, I want to keep the original order as it was, then create 2 new orders each with it’s own product.
Is this possible?

If it helps to know why I need this.
The original order is used for communicating with the customer.
The split orders are used to communicate with the vendors.

Sure, but I cannot help you without seeing the settings, so please use the urgent help option under the help tab on the settings page.
