PowerShell Sc;ript

I am getting the error below everytime I run the this powershell script I have created. It works fine at my house and my friend's house but not at my job it always gives me the same error below.

Property 'sn' cannot be found on this object; make sure it exists and is settable.

Do you have an alias for surname at home?  Try AdUser.surname instead...

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

Justin YeungSenior Systems EngineerCommented:
sn is a property of Get-Aduser, however it is not the default properties,
you will need to enable it by adding -properties sn or -properties *

example
get-aduser someone -properties sn

Default - DistinguishedName
Default - Enabled
Default - GivenName
Default - Name
Default - ObjectClass
Default - ObjectGUID
Default - SamAccountName
Default - SID
Addon Property - sn
Default - Surname
Default - UserPrincipalName

How do you enable multiple extended properties?
0
sirbountyCommented:
That's not the full script, right?
Can you include these associative lines (28, 34, etc) where the exception is thrown?
Also, can you post how you're getting $user filled - what method?  Mask any sensitive data as needed.

Lastly, lines where you're concatenating, like this:
  $Current = $Current + "," + $ADUser.Title
can be modified like this:
  $Current = "$Current,$($ADUser.Title)"
Hope that helps.

This is not the whole script, but I hope this will help.  I think the problem is those extended properties for $ADUser need to be enabled. let me know if you agree with Justin and me.

You do not "enable" those properties, they are either populated or not set.  Justin's comment was about the properties that are returned by default with the Get-ADUser cmdlet, and when additional properties/attributes beyond the default set are needed then you specify them with the -properties parameter.  It appears that you are already doing that with your Get-ADUser command above.

You will see that error when the object doesn't exist that you're trying to set the property for.  In this case, $ADUser must not exist.

I'm not really sure of the purpose of your script.  Rather than using a command like
$ADUser.givenName = $user.'givenName'
if you're trying to set the attribute for the user in AD you should use the Set-ADUser cmdlet.  If you're trying to do something else, please explain what that is and your reasoning.

And by the way, why do you have a filter of "(ObjectClass -eq "user")" for the Get-ADUser command?  It only returns user objects.

Here is the whole script. Also, what I'm trying to accomplish is to take a spreadsheet sent to me by HR convert it to a .csv file and check each user on that list based on employeeID with what is in AD, and if there are any discrepencies the information on the  spreadsheet provided by HR takes precedence, therefore, that info is used to modify the propertie's attribute value. I have attached my test spreadsheet and the full script.

Try this.  I modified your foreach statement so that the $ADUser check uses an If/Else.  I put the Change-Attribute call inside the try block, but it could be moved out (just leave it in the else block).
Foreach ($user in $hrwareusers)
{
	$EmpID = $user.employeeID
	try
	{
		$ADUser = Get-ADUser -Filter {(employeeID -eq $EmpID) -and (ObjectClass -eq "user") } -Properties employeeID,givenName,sn,title,department,streetAddress,postOfficeBox,l,st,postalCode,telephoneNumber
	}
	catch
	{
		$StrUserError = "There was a problem retrieving user $EmpID"
		Out-File $log -Append -InputObject $StrUserError
		Out-File $log -Append -InputObject $_
	}
	
	if ($ADUser -eq $null)
	{
		$StrUserNullError = "There was no user found with Employee ID of $EmpID"
		Out-File $log -Append -InputObject $StrUserNullError
	}
    Else
    {
	   	try{
	        Change-Attribute
		    Set-ADUser -Instance $ADUser
	    }
	    catch
	    {
		    $StrSetError = "There was a problem saving the user information"
		    Out-File $log -Append -InputObject $StrSetError
		    Out-File $log -Append -InputObject $_

Also, a lot of your If condition checks in the Change-Attribute function reference property names that are not equal to the headers in your .CSV (e.g. "Last name" instead of "surname").  These need to be made consistent with the properties of $user which are present and used in the block following the If condition.
