1、related函数从“一端”拉取省份对应的区域,公式是: 区域= RELATED('区域省份'[区域]) 2、relatedtable函数从“多端”统计每个省份的订单数量,relatedtable获取的是符合条件的表格,所以用countrows作聚合计算,公式是: 订单笔数 = COUNTROWS(RELATEDTABLE('销售记录'))发布...

点击“计算列”,函数编写:获取省份 = RELATED('地域表'[省份]) 在excel中使用vlookup如果没有获取到相关值,则会返回错误值,但是使用related函数的话是返回一个空值,类似与在vlookup外面加了iferror函数处理一样 2.RELATEDTABLE 功能:把事实表中的数据匹配到事实表中,也就是沿着数据一端找多端的数据 语法:RELATED...
