使用 PowerShell 创建 SSRS 数据驱动订阅

Question

Edit: Added the whole converted c# to PowerShell with issue

I'm trying to convert MSDN C# code to PowerShell script. Here's the MSDN link

I almost finished the conversion but I encounter some issues for my last line.

This is the complete error message: Exception calling "CreateDataDrivenSubscription" with "7" argument(s): "There was an error generating the XML document."

Below is the code snippet for the 7th argument in creating data driven subscription.

Here's the PowerShell script:

$Parameters | Add-Member -type NoteProperty -Name $EMPID.ParameterName -Value $EMPID.FieldAlias

$ReportYear = New-Object $ParameterValue
$ReportYear.Name = "ReportYear"
$ReportYear.Value = "2017"

$Parameters | Add-Member -type NoteProperty -Name $ReportYear.Name -Value $ReportYear.Value

$ReportMonth = New-Object $ParameterValue

$ReportMonth.Name = "ReportMonth"
$ReportMonth.Value = "6"

$Parameters | Add-Member -Type NoteProperty -Name $ReportMonth.Name -Value $ReportMonth.Value


$SubscriptionID = $objWebServerProxy.CreateDataDrivenSubscription($Report,$Settings,$arrDataRetrievalPlan,$Description,$EventType,$MatchData,$Parameters)

Here's the C# code

ParameterValueOrFieldReference[] parameters = new ParameterValueOrFieldReference[3];

ParameterFieldReference empID = new ParameterFieldReference(); // Data-driven.
empID.ParameterName = "EmpID";
empID.FieldAlias = "EmpID";
parameters[0] = empID;

ParameterValue reportYear = new ParameterValue();
reportYear.Name = "ReportYear";
reportYear.Value = "2004";
parameters[1] = reportYear;

ParameterValue reportMonth = new ParameterValue();
reportMonth.Name = "ReportMonth";
reportMonth.Value = "6"; // June
parameters[2] = reportMonth;

try
{
    string subscriptionID = rs.CreateDataDrivenSubscription( 
report, settings, dataRetrieval, description, eventType, matchData, parameters);

Can you tell me where did I miss on the conversion?

Here's my whole converted script.

Answer 1

I'm not sure if the way you're creating the ParameterValue instances works - I can't tell for sure since the $ParameterValue declaration is missing, but chances are this causes the problem. You might want to try something more along the lines of this:

$reportServerUri = "http://localhost/reportserver/ReportService2010.asmx?wsdl"
$rs = New-WebServiceProxy -Uri $reportServerUri -UseDefaultCredential -Namespace "SSRS"

# Note the difference, here we use the type generated when creating the webservice proxy:
$ReportYear = New-Object SSRS.ParameterValue 
$ReportYear.Name = "ReportYear"
$ReportYear.Value = "2017"

See my blog post here for a quick tutorial.

Edit To pinpoint which argument of CreateDataDrivenSubscription the error is, try substituting one or more arguments with $null - sure it might be invalid according to the method's documentation, but the null checks only occur once the call has been successfully sent to the server and deserialized.

In other words, if substituting the $Parameters argument with $null does not throw the "error generating XML document", then the error is in the $Parameters argument:

$SubscriptionID = $objWebServerProxy.CreateDataDrivenSubscription($Report,$Settings,
           $arrDataRetrievalPlan,$Description,$EventType,$MatchData,$null)
