By default, the option to hide a calculated column for a content type is grayed out. Some people are able to use SharePoint Designer to hide these columns, but we kept running into an error when saving our changes.
“This column already exists in the list. Choose a different column.”
The workaround, as always, was to use PowerShell. This script also works for hiding Document ID!
Add-PSSnapin Microsoft.SharePoint.PowerShell -ErrorAction SilentlyContinue $web = Get-SPWeb "http://spsite" $list = $web.Lists["Library"] $field = $list.Fields["CalculatedColumn"] #$field = $list.Fields["Document ID"] $field.Hidden= $true $field.Update()
