For the interface between SD shipping and WM, you can also set up immediate or automatic transfer order creation for deliveries.
This process is controlled by the message control function in the SD Shipping component. The condition technique can be used to initiate message type "WMTA" when the delivery is created. The prerequisite for this is that at least one item of the delivery is relevant to WM. The combination "Shipping point / Delivery type" is used to determine the message type.

Depending on the processing time of the message type WMTA, there can be different processing types:
- Time 1 - 3 (processing later)
In this case, the message is processed either via a program set in batch mode or manually via the transaction "Messages for delivery".
Since this processing is executed independently of delivery generation, we refer to it as automatic transfer order creation.
- Time 4 (processing immediately)
Here message processing is initiated immediately after the delivery has been created. Therefore, we call this immediate transfer order creation.
If you want the system to generate transfer orders in the background without any additional activity necessary by the user, we recommend that you use processing times "1" or "2". You can then plan to periodically execute the report RSNAST00 (Selection Program for Issuing Output) with a corresponding repetition time for the message type WMTA.
This variant of processing transfer orders in the system provides significant advantages in system performance in comparison to processing time "4" and is by far the preferred method to use for this activity.
If you choose an appropriately small repetition time period when you set up the system to use report RSNAST00, the time required to create transfer orders is nearly the same as when using time period "4" for immediate transfer order generation.
