分析云 OA中部门分级思路和实现方法

描述：在客户碰到OA中部门分级有如下情况，部门中人员有挂在非末级部门上，如下图：

商务中心是末级部门，**应用事业部为二级部门。由于父子维度要求人员必须挂到末级部门，故使用父子维度无法处理该情况。

处理方式：

此时需要将各级部门都作为末级部门进行考虑处理。

将一级部门、二级部门、三级部门分别取出，并通过合并的方式，按照一级部门、二级部门、三级部门分别形成末级部门的形式，进而实现这种业务。

在做抽取的时候，需考虑将OA中人员单据根据人员ID关联人员和部门表，将部门ID抽取到事实表中，然后将事实表中的部门ID跟部门分级的末级部门ID关联，即实现按照人员的部门进行业务数据统计。

具体参考SQL如下：

--第三级部门

a.SORT_ID,a.path as path,
c.id as dim_id,cast(c.name as nvarchar(200)) as dim_name,
a.id as dim1_id,cast(a.name as nvarchar(200)) as dim1_name,
b.id as dim2_id,cast(b.name as nvarchar(200)) as dim2_name,
c.id as dim3_id,cast(c.name as nvarchar(200)) as dim3_name
