Delivery split require during Loading

Hi All,

I am facing situation where business is not using EM & WM. We are using SAP TM9.1.

Its Truck shipment scenario where planning will be done based on DTR.

FO planning and carrier selection is in SAP TM.

I am finding at the time of Loading many times Business is not able to load complete planned Freight units. This is because transporter is not able to send required Truck. Truck dimensions are not standard. Due to this delivery split require.

How to achieve this?

Can we achieve this by integrating Freight Order to ERP shipment? Do Shipment support delivery split and update Freight order in TM?

Any other suggestion to achieve this also welcome.
