Calculate Percent on Compliance SCCM Powershell by Device collection

NAN2019 

I did another small update to provide a better output for a single Assignment ID

if ($GetonlyOne -notlike $null){

 Write-Host $SinglePack.AssignmentName
    $packinfo=Get-SCCMSoftwareUpdateStatus -DeploymentID $GetonlyOne
        $Status=$packinfo.status | Get-Unique
        foreach ($sinlgestatus in $Status){
        Write-Host "The Status of $($sinlgestatus) for $($GetonlyOne)" 
            ((($packinfo | where {$_.status -like $sinlgestatus})).status.count / ($packinfo.Count -4)).tostring("P")
        

            }
return
}

$Packages= Get-AllPackages

foreach ($SinglePack in $Packages) {
Write-Host "--------------"
    Write-Host $SinglePack.AssignmentName
    $packinfo=Get-SCCMSoftwareUpdateStatus -DeploymentID $SinglePack.AssignmentID 
        $Status=$packinfo.status | Get-Unique
        foreach ($sinlgestatus in $Status){
        Write-Host "The Status of $($sinlgestatus) for $($SinglePack.AssignmentName)" 
         ((($packinfo | where {$_.status -like $sinlgestatus})).status.count / ($packinfo.Count -4)).tostring("P")
        

            }
} 

 The call should be like this

.\ScriptName -GetonlyOne 16777338

and the output should be similar to this

WindowsServer 2016_2_2020-10-15 17:03:49
The Status of InProgress for 16777338
9.09 %
The Status of Success for 16777338
90.91 %

For the second one, I really did not understand how you want to fit the Collection Name here. can you explain a requirement to understand it.
