Send data from Abap to Webdynpro

Question

Hello,
I want to do a simple exercise. I created a Webdynpro with one view. In the component controller I have one node with one attribute, a material( type Matnr ). I set it to be Read only.
I have also an Abap program where i select a material.
I want to send the material to the webdynpro so when i test the webdynpro, the material will appear in the view.  How do i bind the material from the Abap program to the webdynpro?
Thank you very much,
Efren

Be careful with the shared memory approach. From my comment in the linked wiki entry:
This approach is actually not that reliable. In post production servers you have more than one application server. When the WDA application opens, due to load balancing there is no guarantee that the user session for the WDA application will be on the same application server as the originating SAPGUI screen (or whatever your original process was).
Share memory objects exist in the global memory of the application server. They do not cross application servers. Unless you use some RFC based tricks to propigate your shared memory objects across all application servers, you will likely find that this approach fails some times in production systems with multiple application servers.
I would instead suggest passing small amounts of information via URL parameters. For larger amounts or data types that can't easily be converted to strings, you should consider writting the data into the database temporarily (perhaps as a server cookie). This is the only way to ensure persistence in a multiple application server environment.
