使用powershell自动化Analysis services表分区

您好，我有AnalysisServices中的表列表，我必须每周手动创建表分区，比如7天。。我必须手动转到分区并更改日期范围，然后处理分区，然后执行。我想使用powershell自动化此过程。下面是我的PS代码片段，我正试图用它实现自动化，但我想了解如何读取partitioncreate命令

function Invoke-SSASCreatePartition
{
    [CmdletBinding(DefaultParameterSetName = "conn")]
    param(              
        [Parameter(Mandatory=$true, ParameterSetName = "connStr")] [string] $connectionString,
        [Parameter(Mandatory=$true, ParameterSetName = "conn")] [Microsoft.AnalysisServices.AdomdClient.AdomdConnection] $connection,
        [Parameter(Mandatory=$true)] [string] $database,
        [Parameter(Mandatory=$true)] [string] $table,
        [Parameter(Mandatory=$true)] [string] $partition,
        [Parameter(Mandatory=$true)] [string] $query,
        [Parameter(Mandatory=$true)] [string] $datasource
        )           

   $cmdText = "
    {
        `"createOrReplace`": {
            `"object`": {
            `"database`": `"$database`",
            `"table`": `"$table`",
            `"partition`": `"$partition`"
            },
            `"partition`": {
                `"name`": `"$partition`",
                `"source`": {
                    `"query`": `"$query`",
                    `"dataSource`": `"$datasource`"
                }
            }
        }
    }"

    if ($PsCmdlet.ParameterSetName -eq "connStr")
    {   
        $connection = Get-SSASConnection -connectionString $connectionString -open                                                          
    }

    Invoke-SSASCommand -connection $connection -commandtext $cmdText

    Write-Verbose "Partition $partition successfully (re)created!"      
}

另外，我在下面附加了partition create命令：

  "createOrReplace": {
    "object": {
      "database": "New_with_date_col",
      "table": "GPS Extraction-MUV-OSD Targets - Fact",

    },
    "partition": {
