Auto Reorder check in group does not check children warehouses


I have a question regarding the intended use of the auto reorder levels.
Given is the following exemplary warehouse tree:

Store -> A -> A-1 -> A-1-B

So we have multiple levels of warehouses. Now given an item that has stock in A-1-B, I get a “Bin” for this warehouse containing the actual and projected qty etc. of said item (>0).

If I now set a auto reorder level to check in the group warehouse “Store”, “erpnext.stock.reorder_item.reorder_item” check for the Bin with the warehouse “Store”, which always returns 0 for actual and projected qty.
Thus, ERPNext will trigger a Material Request despite the fact that this reorder level has not been reached yet due to there being quantities available in the child warehouse “A-1-B”.

Interesting to note: I have no documents of type “Bin” in the system for the intermediary groups in the warehouse tree. Only for the actual warehouse leaf/endpoint and for the root node.

Is this working as intended or am I not getting the whole picture here? Many thanks for any hints or help in advance.


Edit: I made a quick fix that allows the projected qty calculation to propagate beyond the first parent level. See attached patch. Seems simple enough
