Dynamic Groups Question

So I've go this script below that shows me all group membership changes to this  AD group but is there a way to only show removal of objects?  

Get-QARSOperation -TargetObject nameofadgroup -OperationType 'GroupMembershipChange' -Proxy -CompletedAfter ((get-date).AddDays(-4)) -SizeLimit 0 |
Select-Object @{Name="AttributeChanges";Expression={$_.AttributeChanges.Name -join ','}},
@{ name="Group"; expression={ $_.TargetObjectInfo.dn }},
@{ name="Date"; expression={ $_.Initiated }},
@{ name="PC"; expression={ $_.AttributeChanges.Values }} | export-csv C:\Temp\results.csv -NoTypeInformation

Hi rws 

The operation performed against the member attribute is listed under AttributeChanges.operation property of the operation, in this instance Add or Remove. For other attributes that operation value will be different, for instance replace.

$TargetStart = (get-date).AddDays(-6)
$TargetEnd = (get-date).AddDays(-4)
$ServiceAccountDN = "<Your Service Account DN>"
$Operation = "Remove"
$OutputFile = "C:\Temp\results.csv"

Get-QARSOperation -CompletedAfter $TargetStart `
                  -CompletedBefore $TargetEnd `
                  -InitiatedBy $ServiceAccountDN `
                  -OperationType GroupMembershipChange `
                  -OperationStatus Completed `
                  -SizeLimit 0 `
                  -Proxy `
                  | Where-object {$_.AttributeChanges.operation -eq $Operation} `
                  | Select-Object @{Name="AttributeChanges";Expression={$_.AttributeChanges.Name -join ','}}, 
                                  @{ name="Group"; expression={ $_.TargetObjectInfo.dn }}, 
                                  @{ name="Date"; expression={ $_.Initiated }},
                                  @{ name="PC"; expression={ $_.AttributeChanges.Values }} `
                  | export-csv $OutputFile -NoTypeInformation

The other changes I made to your script, was to parametrise the inputs, but also filter the operations on both a completed after and complete before value, rather than returning every operation before a certain date, and also filtering only on the Active Roles service account and also removing the check on a particular group. Naturally you can amend as required for your use case.

Hope this helps

yes it does help, thank you so much, this is perfect
