我已经成功地将我的数据转换为数月。但是,数据透视表只返回在我的 KPIData 表中具有值的行。
我正在针对 KPIData 旋转 Months,并从 KPIGraph 中引入一些字段进行过滤。每当我添加 KPIGraphs 行并且 KPIData 中没有相关记录时,我希望能够在每个月列的行中显示空值。目前,这只适用于我在我的 KPIData 表中添加至少 1 个值,然后由于连接而将所有内容链接在一起。
关系设置如下:http: //goo.gl/9lvhF
我做了一些阅读,发现我需要在这里使用交叉连接?我从未使用过其中之一,经过进一步挖掘后,它在我的数据透视 sql 中的实现完全让我感到困惑。

对此的任何帮助表示赞赏。
