Sales header text to be copied to Delivery document(DelThrough the Project)

Hi,

We are creating sales order, which inturn creates Project in the system (Project System is integrated with Sales).

For creating the delivery usually we use VL01n but

We are creating a delivery document through transaction CNS0 since this delivery comes from Project.

Now the issue:

When we create the original Sales order, we maintain Shipping Instructions in sales order Header data.

Now,

when we are creating the delivery process like picking, Packing through VL02n (based on the document number created by CNS0) , we want the text entered in shipping Instructions in Sales order to be copied automatically to delivery header text, "Shipping Instructions". .

Please let us know if someone has faced such an issue and has a solution.
