power-bi：使用切片器获取计数

Question

我有一个几乎可以创建一个合适的帕累托表的度量：

ParetoTable = 
summarize(
   allselected(alarms),
   ALARMS[WEEK],
   ALARMS[PRODUCT_SUB_FAMILY],
   ALARMS[MFG_STEP_NAME],
   ALARMS[TEST_PROGRAM_NAME],
   ALARMS[TEST_PROGRAM_VERSION],
   ALARMS[LOT_ID],
   ALARMS[WAFER_NUM],
   ALARMS[EQUIPMENT_ID],
   ALARMS[PROBECARD_LOADBOARD_ID],
   ALARMS[EXCEPTION_CATEGORY],
   "key", ALARMS[Week] & "-" & ALARMS[PRODUCT_SUB_FAMILY] & "-" & ALARMS[MFG_STEP_NAME] & "-" & ALARMS[LOT_ID] & "-" & ALARMS[WAFER_NUM] & "-" & ALARMS[EQUIPMENT_ID] & "-" & ALARMS[PROBECARD_LOADBOARD_ID] & "-" & ALARMS[TEST_PROGRAM_VERSION],
   "ExceptionCategoryTotal", sumx(alarms, ALARMS[ExceptionCategoryCount]),
   "TotalExceptions", countrows(ALLSELECTED(alarms))

)

唯一的问题是TotalExceptions变量，它返回ALARMS表中所有行的计数。 我需要的是过滤表的总和，它等于ExceptionCategoryTotal变量的总和。

谢谢
