DAX Calculated Column is not working correctly
I have the following table with over 10K records in my SSAS Tabular model
Client Episodes Monthly Rollup:
I need to create a Calculated Column in DAX - [DaysGroups].
This Column should assign days intervals - "0-90" Days, "91-180" Days, "181-270" Days," 270+" Days, based on the highest [LengthOfStayToDate] value, for each [ClientWHID], where [DischargeDate] = 2050-12-31 and [EpisodeStatus] = "ACTIVE".
In the example above - there are 2 ClientWHIDs - 30636, 37623.
If [ClientWHID] = 30636,
[DischargeDate] = 2050-12-31 and
[EpisodeStatus] = "ACTIVE",
then - the highest [LengthOfStayToDate] value for this Client is 335.
This means, my Calculated Column [DaysGroups] should assign "270+" Days interval for all records where [ClientWHID] = 30636.
If [ClientWHID] = 37623,
[DischargeDate] = 2050-12-31 and
[EpisodeStatus] = "ACTIVE",
then the highest the highest [LengthOfStayToDate] value for this Client is 2 (only one value in this example).
This means, my Calculated Column [DaysGroups] should have all records "0-90" Days for [ClientWHID] = 37623.
I have the following DAX code, but it assigns my ALL ClientWHIDs with "270+" Days interval
VAR ActiveRecords =
CALCULATETABLE (
'Client Episodes Monthly Rollup',
FILTER (
'Client Episodes Monthly Rollup',
'Client Episodes Monthly Rollup'[EpisodeStatus] = "ACTIVE"
&& 'Client Episodes Monthly Rollup'[DischargeDate] = DATE ( 2050, 12, 31 )
)
)
VAR MaxLOSByClient =
SUMMARIZE (
ActiveRecords,
'Client Episodes Monthly Rollup'[ClientWHID],
"MaxLOS",
MAXX (
'Client Episodes Monthly Rollup',
'Client Episodes Monthly Rollup'[LengthOfStayToDate]
)
)
VAR MaxLOS =
MAXX ( MaxLOSByClient, [MaxLOS] )
RETURN
SWITCH (
TRUE (),
MaxLOS >= 0
&& MaxLOS <= 90, "0-90",
MaxLOS >= 91
&& MaxLOS <= 180, "91-180",
MaxLOS >= 181
&& MaxLOS <= 270, "181-270",
MaxLOS > 270, "270+",
BLANK ()
)
It results with ALL my ClientWHIDs = 270+ Days interval
See below, from my model -
Please - HELP!!!

I need to create a Calculated Column in DAX - [DaysGroups].
Are you sure you want to do that from a connection to a SSAS tabular source? Is your data model in mixed mode?
Usually this would have to be a measure, or implemented in the source.

The answers for the 1st 2 questions are "Yes"
If this can be a measure - that's ok! Anything that will work the way I described
