Hyperlinks not visible in UI

Question

Hi All,
My requirement is to add two hyperlinks DISPLAY and CHANGE for the purchase order number. For this I proceeded like this:
1) I created two custom attributes DIS_PO and CH_PO under context node HYPERLINKS of the view IncidentHeader of SRQM_INCIDENT_H.
2) Created Event handlers for the above two attributes and defined the generic object mappings(logical link ids).
3) Redefined the Get_P methods of the above two attributes by specifying the event handlers created above.
4)Added the two hyperlinks beside the purchase order number field in the configuration settings of the view.
Problem is the two hyperlinks are visible in the configuration section in GUI but when I login in UI, hyperlinks are not visible beside the purchase order number field.
Any suggestions would be of great help.
Regards,
Narendra

The issue is caused when migrating from 2010 to 2013. Microsoft’s upgrade process seems to have missed an update required to the Workflow History list, and the following powershell fixes it, with the key being the .SystemUpdate($false) on each item in the workflow
history list:
$url = 'http://mysite/myweb' #todo: update powershell to loop through all sites
$site = new-object microsoft.sharepoint.spsite($url);
Write-Host $site.allwebs.count
$web=$site.OpenWeb();
$spListColl = $web.Lists
foreach($list in $spListColl)
if($list.Title -eq "Workflow History")
foreach ($listItem in $list.Items)
$listItem.SystemUpdate($false)
Write-Host "Updating Items Done"
