dynamic parameter passing in Enterprise portal

Hi All,

Please let me know the steps for how to pass dynamic parameters to Enterprise portal when the shipment id which changes dynamically that wanted to pass to EP URL.

this shipment id which is accessed by Z Function module in the back end  that shipment id has to be passed to EP URL as parameter.

This Z function module will form the complete URL by passing shipment id as parameter to EP URL and that complete EP URL is being sent to user as an email.

once the user receives the complete URL thru email  then user will see the shipment details in the web browser. In UI (webdynpro ABAP UI)

Thanks
