Unlike what is mentioned on many articles, using SystemUpdate() is able to our enterprise wiki pages without creating new versions

Question

I am working on an enterprise wiki site collection inside sharepoint on-premises 2013, and i want to update a field named "PageNumber", without affecting the modified, modifedby & version number, so i wrote this powershell script and i run it inside a test wiki site:-

$site = get-SPWeb http://**/site/customerwiki/
#specify the list name 
$list = $site.Lists["Customer KB"] 
$listitems = $list.Items 

foreach ($listitem in $listitems) 
{ 
    write-host $listitem["ID"] "processed"
    $listitem["PageNumber"] = $listitem["Initial"]+$listitem["ID"];
    $listitem.SystemUpdate()
    write-host $listitem["Name"] "has been updated." 

} 

where the wiki pages got updated without creating new version or update the modified-by or modified date.. now i am asking this question as i found many articles which mentioned that suing SystemUpdate() will create new versions such as this link:- How to Update SharePoint List Items without Creating New Versions

so can anyone advice on this?

Answer 1

Use .SystemUpdate(false) which will not create a new version.

SPListItem.SystemUpdate Method

Answer 2

SystemUpdate() is the same as SystemUpdate(false)

SPListItem.SystemUpdate method

Calling this method is the same as calling SystemUpdate(Boolean) with false.

Source: Microsoft Docs. I might be a bit old fashioned, but what is wrong with checking the official documentation? :)

Answer 3

You have to pass true as a parameter in order for it to increment the version number:

$listitem.SystemUpdate($true)

MSDN documentation on SystemUpdate().
