Stock Transfer Orders for different sales areas from a supplying plant

Hi,

In the past, customer D4503 was assigned to plant 4503 in IMG-Materials Management-Purchase Order-Set up stock transfer order in sales area 4000, 20, 29. Now, the client wants to do stock transfers in the sales area 4000, 20,33. At any point in time, can we have stoc transfers from a plant in only one sales area?

Thanking you in anticipation,

Regards,

Kasturi
