Link to a document in a document library when the document is stored/Updated in document library
Follow the below steps to do Link to a document using OOTB.
We use the Content Type “
Link to a Document” to link to a document that could be stored in another document library.
If the document library where you want to
use the “Link to a Document” hasn’t been setup to use Content Types,
you’ll have to click
Settings,
Document Library Settings, there you’ll need to access the
Advanced Settings.
We need to add a Content Type, but before we can do this we’ll have
to tell our Document Library that it can make use of different Content
Types. Select “
Yes” for the “
Allow management of Content Types“.
When you return to the
Document Library Settings, you’ll see a new section called
Content Types, this is where we’ll add a new Content Type, click “
Add from exisiting Content Type“.
The content type we need is “
Link to a Document“, add it here.
When you return to your
Document Library and click
new, you’ll see that you have a new option to choose from, “
Link to a Document“.
Let’s make a link to a Document in another Document Library, click “Link to a Document”. You’ll have to enter a
name for the Link and enter the
path to the Document you want to link to.
After confirming this is what your link looks like.
We made link to a document that’s saved in another document library,
whenever you make a change to the master document, you don’t need to
worry about the link, it will point to the changed document.
In the same way we can put "link to a document" links in another folder with in the Documnet library using Object Mode, Here i am using Event handler to Create Link to document when new item is Added in Document Library
