Powerbi 创建员工-经理关系表,powerbi,dax,powerquery,powerbi-desktop,Powerbi,Dax,Powerquery,Powerbi Desktop,我有一张桌子，如下所示：原始表格： +---------------+--------------+--------------+ | Employee Name | Manager Lvl1 | Manager Lvl2 | +---------------+--------------+--------------+ | A | L | Y | | B | M | Y

我有一张桌子，如下所示：

原始表格：

| 13 | Z        |            |

我想向所有员工级别添加一个id，并添加一个列，指定每个员工的经理id，如下所示：

所需员工表：

+---------------+--------------+--------------+
| Employee Name | Manager Lvl1 | Manager Lvl2 |
+---------------+--------------+--------------+
| A             | L            | Y            |
| B             | M            | Y            |
| C             | L            | Y            |
| D             | M            | Y            |
| E             | N            | Z            |
| F             | N            | Z            |
| G             | O            | Z            |
+---------------+--------------+--------------+

+----+----------+------------+
| ID | Employee | Manager ID |
+----+----------+------------+
|  1 | A        |          8 |
|  2 | B        |          9 |
|  3 | C        |          8 |
|  4 | D        |          9 |
|  5 | E        |         10 |
|  6 | F        |         10 |
|  7 | G        |         11 |
|  8 | L        |         12 |
|  9 | M        |         12 |
| 10 | N        |         13 |
| 11 | O        |         13 |
| 12 | Y        |            |
| 13 | Z        |            |
+----+----------+------------+

我这样做的主要目的是添加一个path列来创建每个员工-经理关系的路径，以便添加行级安全性：

我将使用的路径函数是：

EmployeePath= Employee[ID], Employee[Manager ID])

因此，我的结束表将如下所示：

+----+----------+------------+---------+
| ID | Employee | Manager ID |  Path   |
+----+----------+------------+---------+
|  1 | A        |          8 | 12|8|1  |
|  2 | B        |          9 | 12|8|2  |
|  3 | C        |          8 | 12|8|3  |
|  4 | D        |          9 | 12|9|4  |
|  5 | E        |         10 | 13|10|5 |
|  6 | F        |         10 | 13|10|6 |
|  7 | G        |         11 | 13|11|7 |
|  8 | L        |         12 | 12|8    |
|  9 | M        |         12 | 12|9    |
| 10 | N        |         13 | 13|10   |
| 11 | O        |         13 | 13|11   |
| 12 | Y        |            | 12      |
| 13 | Z        |            | 13      |

我刚刚很难将我的原始表转换为所需员工表的格式

您可以在Power Query Editor中执行一些转换以获得所需的输出。假设您的表名为Employee，结构如下-

现在，转换有点长，但是试着一步一步地理解。如果你能理解，事情就会变得容易。复制您的表员工，并替换为来自高级编辑器的以下代码-

let
    Source = employee,
        
    L0 =    
    Table.Distinct(         
        Table.FromList(
            Table.Column(Source,"Employee Name"),
            Splitter.SplitByNothing(), null, null, ExtraValues.Error
        )
    ),
