Get-SCSMObject : Cannot bind parameter 'Id

Hi Guys,

Trying to run this in a runbook. Monitor new Change requests and then run this PowerShell.

Want it to update the Assigned to user to matched the created by but getting the below errors. I know it's around the ID I am passing through but not sure how to pass the GUID through via this or orchestrator. Any Ideas?

Thanks.

Import-Module SMlets
$smDefaultComputer = "MGMT SERVER"

$CrID = "CR41111"

$crClass = Get-SCSMClass -name System.WorkItem.ChangeRequest$

$thisCR = Get-SCSMObject -id $CrID

Write-Output "Got CR: $($thisCR.Id)"

$assignedUserRel = Get-SCSMRelationshipClass -Name System.WorkItemAssignedToUser

$createdByRelClass = Get-SCSMRelationshipClass -Name System.WorkItemCreatedByUser

$createdRelationship = Get-SCSMRelationshipObject -BySource $thisCR | ?{$.relationshipid -eq $createdByRelClass.id -and $.sourceobject.classname -eq $crClass.Name}

$createdUser = Get-SCSMObject -id $createdRelationship.TargetObject.Id

Write-output "Assigning to $($createdUser.displayname)"

New-SCSMRelationshipObject -Relationship $assignedUserRel -Source $thisCR -Target $createdUser -Bulk

Hi @ alfiethomas-8724

please try this:

 Import-Module SMlets
 $smDefaultComputer = "MGMT SERVER"
 $CrID = "CR41111"
 $crClass = Get-SCSMClass -name System.WorkItem.ChangeRequest$
 $thisCR = Get-SCSMObject -Class $crClass -Filter "ID -eq $crID"
 Write-Output "Got CR: $($thisCR.Id)"
 $assignedUserRel = Get-SCSMRelationshipClass -Name System.WorkItemAssignedToUser
 $createdByRelClass = Get-SCSMRelationshipClass -Name System.WorkItemCreatedByUser
 $createdUser = Get-SCSMRelatedObject -SMObject $thisCR -Relationship $createdByRelClass
 Write-output "Assigning to $($createdUser.displayname)"
 New-SCSMRelationshipObject -Relationship $assignedUserRel -Source $thisCR -Target $createdUser -Bulk

It looks to me to be pretty simple: The cmdlet (or, in this case, a SMLet --whatever that is) wants the -id parameter to have an argument that is a GUID, not a text string that holds the name of something.

Hi Rich.

Definitely wants the 16 digit GUID of the change and have actually been able to get that working now manually if i enter the guid of a certain change it runs.. Updates the Assigned to user to match the afftected user.

IIt's just how I push through the GUID of each new change that is created so it runs each time.
