Time Can'；无法正确检索上一季度的上一次不同计数

我使用一个查询来检索不同的计数公司和产品，如下所示。 我无法检索通过的整个期间（本例中为第1季度）的不同计数：

如果我用e DATEADD生成最后一个季度（“季度”、-1“期间”），我就有了QTD。你知道我该怎么处理吗

预期结果：

您好-您不必通读您的代码并试图理解逻辑，请您用文字解释一下company_Q和company_q1代表什么以及如何计算它们？Hello@NickW，

CompanyQ=distinct count company**quarty to date**

表示如果您有一个期间，您将计算实际季度开始和当前季度期间之间的所有不同公司。company_Q1意味着，我希望上一季度所有公司的计数都不同。
