Please check the Customizing "Maintain Storage Types" -> Putaway Control, there can be limitation of the putaway control.

It is mandatory that the flag "No Mixed Stock Types" is not set for a storage type which is used for QQ to FF postings.

Additionally, there can be decision made for nested HUs is like below.

Stock situation before decision is like:

Storage bin 01-01-01

     HU 3000000001(Highest HU)

           -> HU 3000000002(Sub-HU) Stock type Q

           -> HU 3000000003(Sub-HU) Stock Type Q

The HU 3000000001 is assigned to an inbound delivery delivery, Insp. Lot Summary is set as “One Insp. For Product/Batch and Inbound Delivery”. All the HUs share one inspection lot.

After decision made, the stock is expected to be change from QQ to FF. System do stock type change one by one for the sub-hu. If the flag "No Mixed Stock Types" is set, it is intended there is stuck queue.
