How to enable the division of shipments by warehouses in warehouse accounting in BIS?

Question

1C-Bitrix

There is a setting in the BUS "Enable warehouse accounting" to activate a simple accounting for warehouses. Created several warehouses and a document for the arrival of test goods (receipt of 10 pieces to one warehouse and 5 to another). Placed an order for all 15 pieces - one shipment was created, in which the default warehouse is specified, quantity = 15 pieces, 10 pieces are available.
Does Bitrix have automatic division of shipments into warehouses based on balances or do I need to write a handler?

Answer 1

I asked this question a long time ago, I'll answer it myself, suddenly it will be useful to someone.
Bitrix does not distribute goods among warehouses during warehouse accounting. You need to write a handler and scatter the goods yourself.
When accounting is enabled, when editing an order in the admin panel, it displays fields for selecting a warehouse. The manager can set a different warehouse for each item by selecting the desired one from the drop-down list. The list will contain warehouses for which there is a balance for this product.
