Avail. check in subcontracting orders

Hi guys,

I have recently faced an issue that must be a well-known problem. Unless I am doing something wrong.

When you place a subcontracting PO, its components are reserved in stock. The problem is that the availability check is not started automatically when the order is placed, but must be explicitly triggered by the user on the component screen.

This creates two problems:

- There's no warning about unavailability of components

- The reservations are not confirmed (committed), which means that the other orders (prod. orders, sales orders) competing on the same stock don't see them and reserve the stock for themselves.

I wonder if there's a way in standard SAP (either customising or a user exit) to force availability check of the components.

TIA
