使用 Azure 自动化流程 SSAS 表格模型

Question

我有使用 Azure 数据工厂在 Azure SQL 数据库上提取数据、处理和抽取数据的过程。最后，来自 Azure SQL 的数据由 SSAS 表格模型使用。到目前为止，直到将数据泵入 Azure SQL 的整个过程都是使用 Azure 数据工厂 v2 自动完成的，但我无法找到自动处理 SSAS 表格模型的方法。请让我知道是否有办法做到这一点。

我希望它由 ADF v2 以某种方式触发，以便表格在新数据被注入 SQL 时立即获取更新数据。由于我无法使用 ADF v2 做到这一点，我尝试使用 Powershell。我在这里面临的障碍是，我需要通过两个凭据来处理表格 1. Azure SQL 的 SQL 服务器身份验证 2. 模拟一个用户的 Windows 凭据 我对 Powershell 非常陌生，在传递这两个凭据时遇到问题

Powershell 脚本：-

$Transactional="Y", $Parallel="Y",$MaxParallel=2,$MaxCmdPerBatch=1, $PrintCmd="N",
