Our Criteria is :
We need to add Ship to name, address ,city ,post code field on Source document page.
In our standard code work : On warehouse shipment page ,there is an one action i.e.Get Source document. We clicked on that action & it will Open the list of released source documents such as sales order,etc.
Like below screenshot ,In our standard functionality, We already have Source no.& this Source No is our sales order number
Like similar way I want to do customization for Ship-to name field .& this ship-to-name field data is coming from sales header-Ship to name field.
