Get-SCSMObject : Cannot bind parameter 'Id

Question

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.
