Currently I'm displaying orders and related objects in a visualforce page. The new requirement is:
For every order a hyperlink/button will be added.
On clicking that button, a related document from SAP server will be downloaded using a unique number (order id).
For example: (http: www.somelink.com/id=12345)
How would I need to start this? I know how to expose a webservice from apex. I'm pretty excited because this is a great opportunity for me to learn webservices in salesforce.
Suggestions and references would be appreciated. Thanks.
