Transfer posting from plant to plant at the time of sales order

Hello SD gurus,

I need your help to map the scenario below :

Physically my stock is in city A (which corresponds to a plant A in SAP).

I have customers in both city A and city B (city B corresponds to a plant B in SAP).

Both plants belongs to the same company.

When a customer from city B makes a sales order, I want to be able to make a transfer posting from pant A to plant B at the time of sales order and make the entire sales flow from the plant B.

Is that possible in standard SAP ? How ?

Regards,

Bahia.
