Power BI 虚拟关系RLS禁用的权限控制

需求场景

构建权限时,所需构建角色的维度表,与其他明细表的关系是虚拟关系。

Power BI在使用userelationship或Crossfilter函数时,会与RLS冲突。

那么,如何在这种冲突的场景下,继续构建权限呢?

方案思路

本文方案基于dax公式:

1. 计算组(需下载tabular editor)

2. 函数过滤

3. 权限配置表(如需计划刷新,配置表路径需处于sql或sharepoint/onedrive)


另外,也可以将虚拟关系的两个列 作为两个表分开,以此避开虚拟关系,就不用这个方法了。


案例实现

  1. 前提信息

region/branch 区分 领导 region/branch, 执行 region/branch

因此构建模型如下:维度表分别与明细表关联,使用虚拟关系动态激。

2. 权限表准备

权限将基于以下信息构建。

1)根据role key,区分是什么类型的role

2)根据员工id,确认拥有的权限行

3)分别筛选region branch 客户ID等信息

3. 实现

1)打开tabular editor

  1. 创建计算组

Model > New calculation group
创建计算组后,右键计算组,创建新的item(领导region、执行region)

其中dax如下

领导:(激活region维度表与领导分公司相关的列的关联,[@testofremove]measure不受该计算组影响)

    CALCULATETABLE (
        SUMMARIZE ( Access, Access[Role Key], Access[区域], Access[分公司], Access[客户ID] ),
