I'm trying to change the setting of a column to make it not a required field. This is the code I'm using:

$site = new-object Microsoft.SharePoint.SPSite("abc.com")
$web = $site.OpenWeb()

$MyContentType=$web.ContentTypes["ContentType"]
$MyField=$MyContentType.Fields | Where {$_.Id -eq $web.Fields["Column"].id}
$MyContentType.FieldLinks[$MyField.Id].Required=$False 

$MyContentType.Update()

But this is giving error that $MyContentType.FieldLinks is NULL. How can I successfully execute my PowerShell script?

    Two notes here, a bit off topic: 1. There is no need to open an SPSIte object first - go straight for the SPWeb: $web = Get-SPWeb "example.com" 2. Dispose of opened SPSite and SPWeb objects by calling .Dispose(); Dec 29, 2015 at 10:51

Try this code.

$web = get-spweb $url
$MyContentType = $web.ContentTypes["ContentType"]
$field = $MyContentType.FieldLinks["Column"]
$field.Required = $False 
$MyContentType.Update()

Try this

$site = new-object Microsoft.SharePoint.SPSite("abc.com")
$web = $site.rootweb

$MyContentType=$web.ContentTypes["ContentType"]

$Fields=$MyContentType.Fieldlinks
$Field=$Fields["Internal Name of the Field"] #Type $MyContentType.Fieldlinks to get the details of all the fields.
$Field.Required=$false
$MyContentType.Update()
