I want to refer master page of my root site collection on other site collections
Site Collection A : https://www.siteA.com/
Site Collection B : https://www.siteA.com/sites/siteB/, from this site collection I need to access master page of Site Collection A.
Below is the page directive in one of the pages in site collection B (in Pages folder) by which I am trying to access master page of site collection A.
"<%@ Page language="C#" MasterPageFile="~site/_catalogs/masterpage/sitea.master" inherits="Microsoft.SharePoint.WebPartPages.WebPartPage, Microsoft.SharePoint, Version=18.104.22.168, Culture=neutral, PublicKeyToken=71e9bce111e9429c" meta:progid="SharePoint.WebPartPage.Document" %>"
But this page directive refers to master page on site collection B instead of A. Please let me know how can I successfully access root site collection master page on one of the other site collections.
Thanks in advance
