SharePoint By Yagya Shree

Preventing me from adding any additional column in existing list and /_layouts/mngfield.aspx extremely slow to load for sub sites

1. Trying to ‘Add from existing site columns‘ to one of my SharePoint lists on a http://SiteUrl
An unexpected error has occurred.
Correlation ID: GUID


2. Click on Site Settings->Site Columns ( http://SiteUrl/_layouts/mngfield.aspx ) extremely slow to load for sub sites

Root cause:

Looking up that Correlation ID in the SharePoint 2013 ULS logs I saw this error:

“Error when access /_layouts/15/AddFieldFromTemplate.aspx, Error=No two choices should have the same ID at Microsoft.SharePoint.ApplicationPages.ChoiceComparerWithDefaultGroup.Compare”

Found two Site Columns in http://SiteUrl Site that was using the same internal name, and that Site column was associated with list which is preventing me from adding any additional columns.

By browsing to the Site Collection Site Columns (<Site Url>/_layouts/mngfield.aspx ) I noticed under one of Site Column Group that there were two Site Columns listed with the same “CoulmnName”,

We need to remove duplicate Site Columns from that Site Column Group.
