powerbi - Dax 中的行号

Question

我有以下 DAX 代码。我需要自动增加行号，其中 FileNo 和 CI_No 代码相同。我厌倦了 RANKX 函数，但它对所有记录返回排名为 1。任何人都知道我们如何使用 DAX 实现这一目标。

提前致谢。

达克斯代码：

DEFINE
VAR A = UNION(   ROW ("FileNo",  10, "CI_No", 101, "Amount" ,100)
                ,ROW ("FileNo",  10, "CI_No", 101, "Amount" ,100)
                ,ROW ("FileNo",  10, "CI_No", 101, "Amount" ,100)
                ,ROW ("FileNo",  20, "CI_No", 201, "Amount" ,200)
                ,ROW ("FileNo",  20, "CI_No", 201, "Amount" ,200)
                ,ROW ("FileNo",  20, "CI_No", 301, "Amount" ,300))


VAR B=  ADDCOLUMNS(A,
         "RowNo", RANKX(
        FILTER(A,
               [FileNo]=EARLIER([FileNo]) &&  [CI_No]=EARLIER([CI_No]) 
                ),
        [Amount], , DESC
        )        )
 
 EVALUATE B

预期结果

您可以尝试混合使用 AddIndexColumn（来自 TransformData）和新的计算列：

RowNo = 
          RANKX(
        FILTER( ALLEXCEPT('sample','sample'[RowNo]) , [FileNo] = EARLIER('sample'[FileNo]) &&  [CL_No] = EARLIER('sample'[CL_No]) ),
               
                
        [DummySum], , DESC
        )        

DummySum = sum('sample'[索引])

编辑：

Table = VAR A = ADDCOLUMNS(UNION(   ROW ("FileNo",  10, "CI_No", 101, "Amount" ,100)
                ,ROW ("FileNo",  10, "CI_No", 101, "Amount" ,100)
                ,ROW ("FileNo",  10, "CI_No", 101, "Amount" ,100)
                ,ROW ("FileNo",  20, "CI_No", 201, "Amount" ,200)
                ,ROW ("FileNo",  20, "CI_No", 201, "Amount" ,200)
                ,ROW ("FileNo",  20, "CI_No", 301, "Amount" ,300)), "Index", [Amount]+RAND())


VAR B=  ADDCOLUMNS(A,
         "RowNo", RANKX(
        FILTER(A,
               [FileNo]=EARLIER([FileNo]) &&  [CI_No]=EARLIER([CI_No]) 
                ),
        [Index], , DESC
        )        )
 
return B
