.net 使用 Powershell TOM 在 SSAS 表格中创建分区

try 连接到表格模型并在分析服务表格模型上创建分区.下面提到的这段代码.

[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.AnalysisServices.Tabular")
#Here, the variables are declared to be used
$ServerName = "<analysis SERVICE URI>"
$DatabaseName = "ProductReportingModelPartitionTest"

$Server = New-Object Microsoft.AnalysisServices.Tabular.Server
#Connecting to the Tabular Server
$Server.Connect("$ServerName")
#Declaring which Tabular database to connect to
$DatabaseName = $Server.Databases["$DatabaseName"]
$Model = $DatabaseName.Model

function Add-NewPartition ($_table,$_originalPartition) {
   #Find the partition by name in the model
   $PartitionExists = $_table.Partitions.Find("DevPartition")
   echo($PartitionExists | Format-Table)
   #Check if the partition was already created, if not exit. 
   if (!$PartitionExists)
   {
        #Clone the reference partition that has placeholder 1=2
        $NewPartition = $_originalPartition.Clone()
        
        #Give a name to the new partition, something that can be found
        $NewPartition.Name = "deve0osl"
        #Add the new partition
        $_table.Partitions.Add( $NewPartition )
        
        #Call the refresh data process method to refresh the data of the new partition 
        $NewPartition.RequestRefresh("Data") 
   }
}



$Table = $Model.Tables["Online Stock - Seasons"]


$OriginalPartition = $Table.Partitions[0]

Add-NewPartition $Table $OriginalPartition

直到$NewPartition开始工作.但$_table.Partitions.Add( $NewPartition )美元不管用.请帮帮忙，提前谢谢.
