update document description failed:0

Hi,

I am just new in PowerBI for projectwise. I try to update the description of document. But I can not change it with Attribute update failed:0.

The part of code I am using is

[object]$allPwDocuments = Get-PWDocumentsBySearch -Environment "Rendition Attributes"

[int]$numPwDocs = $allPwDocuments.Count

　

[System.Collections.HashTable]$yesAttributes = @{}

$yesAttributes.Add("LATEST_RENDITION_REV", "Noo")

　

Write-Host "$numPwDocs documents returned."

foreach ( $pwDocument in $allPwDocuments )

{

#Write-Host $pwDocument.Name

if ($pwDocument.Name -eq "SMCSWTSE-JAB-TPW-CW-DRG-706707-A.5.pdf" )

{

Write-Host $pwDocument.Name

Write-Host $pwDocument.Description

#Update-PWDocumentAttributes -InputDocuments $pwDocument -Attributes $yesAttributes

#Update-PWDocumentAttributes -InputDocuments $pwDocument -Attributes @{LATEST_RENDITION_REV="Yess"; Description="ferferre"}

Update-PWDocumentAttributes -InputDocuments $pwDocument -Attributes @{Description="ferferre"}

}

}

The error I had is

SMCSWTSE-JAB-TPW-CW-DRG-706707-A.5.pdf
