Getting same load for multiple shipments for 6 of my sales lines in an order ,even though having different shipping career/mode of delivery. what may be the reason?

Hello,

Want some expert advice on my current scenario wherein i am getting same load for multiple shipments but with different shipping career.

Want to know-

1. What are the criteria for load creation if i am not using "automatic load creation at sales order " in the WHS parameter?

does it consider load template and load capacity and decides that how many loads to be created ?

2 What is the role of Load building workbench, how is it useful?

3.What is the role of Load building template and strategy, in what scenarios is it useful?

4. Can anyone differentiate "Mode" and Mode of delivery ? does standard consolidation in D365 depends on 'Mode' like AIR,SHIP etc .not on mode of delivery , as these two are different entity in D365O.

Thanks, for your time and support.
