Create Delivery, Launch Pick release and Ship Confirm sales order Using API

Dear All,

We need to automate Order to Cash Cycle by create deliveries, ship confirm and auto invoice.

How to achieve that using API.

As a first step we downloaded attached document (If there are any better kindly advise)

After following document steps; we stopped at step in page 7 (Assign delivery detail to delivery);

WSH_DELIVERY_DETAILS_PUB.Detail_to_Delivery

error:

Error in assigning one or more details to a delivery.Warning: These entities can not be grouped together as their grouping attributes do not match.

Reading about that error; We should create delivery that have the same grouping attribute (Attached);
