报表中为空cells/offset:如何在多维数据集中定义维度和层次结构?
Empty cells/offset in the report: how to define a dimension and hierarchy in the cube?
我想分析一些过程的一些动态。为此,我将 Saiku 分析插件 CE 用于 Pentaho 商业智能服务器 CE 5.0.1。
有一个 table 的事实和一个 table 的维度用于执行一些聚合。维度表示层次结构 "Year - Month - Day".
我分两次创建了一些报告——按年和按月。报告如下所示:
显示的数据正确:
如果我定义一个独立的维度 "Month",报告看起来是正确的:
但是,数据已经不对了:
我尝试添加反维度"Month - Year",但没有看到任何数据。
有没有一种方法可以定义报表不包含空单元格的维度?
我找到了解决方案 - 问题出在错误的日期维度上。
