Bulk Change SSRS Data Sources using Powershell - powershell

Question

I'm trying to alter a data source for a set of Reporting Services reports, but I can't get the Powershell to work for them. I'd appreciate any help :)
$server = "http://My/ReportServer/"
$dataSource = Get-RsDataSource -Path "/Data Sources/NewDataSource" -
ReportServerUri $server
$reports = Get-RsCatalogItems -RsFolder "/Testing/NewDataSOurce" -ReportServerUri $server -Recurse | Where-Object {$_.TypeName -eq "Report"}
$reports | ForEach-Object {
$reportDataSource = Get-RsItemDataSource -RsItem $_.Path -ReportServerUri $server
$reportPath = $_.Path
if ($reportDataSource.Name -eq "OldDataSource") {
Set-RsItemDataSource -RsItem $reportPath -DataSource $dataSource -ReportServerUri $server
}
}

I wrote a function to do what you are talking about for setting data sources. Here is what I have... Unfortunately I don't have a SSRS instance any longer. The full script / module is on a gist on my GitHub account. I'll paste my gist urls at the bottom on this thread.
The function that I'm pulling the snippet out of is called Deploy-NativeSSRS. I used this module + a driver script to push items that had been checked out of TFS. So they could in turn be parsed and then pushed to SSRS during CI activities.
$reports = New-ReportObject -files (Get-ChildItem -Path $reportPath -Filter $reportExtension)
foreach($report in (($reports | Where-Object{$_.datasourcename -eq $datasourceName}).filename))
{
$fileExt = $reportExtension.trim('*')
$status = Set-SSRSDataSourceInfoNative -ReportName ($report.trim($fileext)) -reportPath $documentLibrary -DataSourceName $datasourceName -DataSourcePath "$dataSourceTarget/$datasourceName" -reportWebService $webservice
write-output "The following $report datasource was updated to $datasourcename"
}
function set-SSRSDataSourceInfoNative
{
param
(
[parameter(mandatory)]
[string]$Reportname, #with no extension SSRS has no name for the file in native mode
[parameter(mandatory)]
[string]$reportPath,
[parameter(mandatory)]
[string]$DataSourceName,
[parameter(mandatory)]
[string]$DataSourcePath,
[parameter(mandatory)]
[uri]$reportWebService,
[System.Management.Automation.PSCredential]$Credentials
)
if ($Credentials)
{$reportProxy = new-webserviceproxy -uri $reportWebService -Credential $credentials -namespace 'SSRSProxy' -class 'ReportService2010'}
else
{$reportProxy = new-webserviceproxy -uri $reportWebService -UseDefaultCredential -namespace 'SSRSProxy' -class 'ReportService2010'}
$f = $ReportName.ToLower()
try
{
$dataSources = $reportProxy.GetItemDataSources("$reportpath/$reportname")
}
catch
{
"Error was $_"
$line = $_.InvocationInfo.ScriptLineNumber
"Error was in Line $line"
"ReportName: $reportname"
"ReportPath: $reportpath"
}
$proxyNameSpace = $dataSources.gettype().Namespace
$dc = $reportProxy.GetDataSourceContents($DataSourcePath)
if ($dc)
{
$d = $dataSources | Where-Object {$_.name -like $DataSourceName }
$newDataSource = New-Object ("$proxyNameSpace.DataSource")
$newDataSource.Name = $datasourcename
$newDataSource.Item = New-Object ("$proxyNamespace.DataSourceReference")
$newDataSource.Item.Reference = $DatasourcePath
$d.item = $newDataSource.item
$reportProxy.SetItemDataSources("$reportpath/$f", $d)
$set = ($reportproxy.GetItemDataSources("$reportPath/$f")).name
write-verbose "$reportname set to data source $set"
$returnobj = 'success'
}
$returnobj
}

Here something that works with Power BI Report Server Rest API:
[string] $uri = "https://xxx/Reports"
$session = New-RsRestSession -ReportPortalUri $uri
$reports = Get-RsRestFolderContent -WebSession $session -RsFolder / -Recurse | Where-Object {$_.Type -eq "PowerBIReport"}
$reports | ForEach-Object {
$dataSources = Get-RsRestItemDataSource -WebSession $session -RsItem $_.Path | Where-Object {$_.ConnectionString -eq "yyy;zzz"}
#$dataSources[0].DataModelDataSource.AuthType = 'Windows'
$dataSources[0].DataModelDataSource.Username = 'domain\user'
$dataSources[0].DataModelDataSource.Secret = 'password'
Set-RsRestItemDataSource -WebSession $session -RsItem $_.Path -RsItemType 'PowerBIReport' -DataSources $dataSources
}
