WMS partial pick doesn't authorise

When you use WMS to pick and order and it's a partial pick for example 6 out of 12 items, the WMS does not create an advanced sale or authorise the fulfilment, without is being authorised it does not secure the stock to that order. It also affects the stock quantity in the bin location as stock isn't allocated to the bin.

I believe when an order is partially picked, it should:

Advance to multiple fulfilment.

Authorise the fulfilment.

If this doesn't suit everyone could it be a setting? to choose advance and authorise on partial fulfilment.

The problem with the current system is:

The stock doesn't allocate to the bin until authorised so it give incorrect counts when counted.

The stock can be scanned on other orders until authorised.

Someone had to log on a Core to convert and authorise instead of the whole process being completed on WMS, this complicates our processes.
