Symptom:
Field notice Alerts showing different URLs at different levels.
 
On high level(IR portal -> Product Alert POD -> Field Alert Notices), we see it displaying
  A very specific product related field notice Alerts.

Whereas in the  drill down, 
IR portal -> Product Alert POD -> Field Alert NoticesAffected devices - IP address View-
 chassis details -> Product Alerts -->
Common URL under drill down view on device  level: 
http://www.cisco.com/public/support/tac/fn_index.html

Conditions:
1) IR -> Product alert -> field notices alerts->  commom/specific field notice  url -> affected devices -> ip address view -> chassis/cards -> product alerts -> field notices
on the online product alert pod, select the field notices alerts, we see the the specific/common URL under the field notices. And when we further drill down  on the affected devices  (chassis/cards) and go to product alerts-> field notices we see the common URL under the device specific level 

2) IR report -> product alert pod ->  export (xml/pdf)
If we download the Product alert report  (offline report) we get common url  under alert definition tab rather than the device specific field alert
