I have the following case:

I issue a sales order with a product of quantity 50. The Sales Flow is as follows:

1- 15 out of 50 will be scheduled to deliver on the same day
2- 15 out of 50 will be scheduled to deliver on the next day

3- 20 out of 50 will be scheduled to deliver after one week

This is the main work of the salesman, he just needs to apply these conditions.

2nd step:

Each Quantity delivered must be sent within a specific route. So, let's suppose I created a route in the system that follows this : Main Warehouse -> Transit Location -> Customer Location. Thus, when the logistics guy picks which route should be applied on each delivery, the route should be directly applied. For example, the first 15 will follow route 1, the 2nd 15 will follow route 2 and the last 20 will follow route 3.

Note: Each quantity the salesman provide must be created later on in a separate transfer. So, in this example , I must have 3 transfers.
