Hello all,
I need to get previous record based on DateTime column and grouped by TagIndex column
I created this measure,
Solved! Go to Solution.
Hi,
Thank you for your sharing.
Could you please try the below if it works?
Prev_value_Energy_consum =
VAR Index = [Index]
VAR Prev_datetime =
MAXX (
FILTER (
ALLSELECTED ( FloatTable ),
FloatTable[Date] = SELECTEDVALUE ( FloatTable[Date] )
&& FloatTable[Time] < SELECTEDVALUE ( FloatTable[Time] )
),
FloatTable[Time]
)
VAR Prev_date =
MAXX (
FILTER (
ALLSELECTED ( FloatTable ),
FloatTable[Date] < SELECTEDVALUE ( FloatTable[Date] )
),
FloatTable[Date]
)
VAR Prev_time =
MAXX (
FILTER ( ALLSELECTED ( FloatTable ), FloatTable[Date] = Prev_date ),
FloatTable[Time]
)
RETURN
SWITCH (
TRUE (),
NOT ISBLANK ( Prev_datetime ),
CALCULATE (
SUMX ( FloatTable, VAR Index = FloatTable[TagIndex] RETURN FloatTable[Val] ),
FILTER (
ALLSELECTED ( FloatTable ),
FloatTable[Time] = Prev_datetime
&& FloatTable[Date] = SELECTEDVALUE ( FloatTable[Date] )
&& FloatTable[TagIndex] = Index
)
),
CALCULATE (
SUMX ( FloatTable, VAR Index = FloatTable[TagIndex] RETURN FloatTable[Val] ),
FILTER (
ALLSELECTED ( FloatTable ),
FloatTable[Time] = Prev_time
&& FloatTable[Date] = Prev_date
&& FloatTable[TagIndex] = Index
)
)
)

Hi @Jihwan_Kim
Thanks for your measure @Jihwan_Kim but there was a small issue with that measure.
Instead I have created this new file with the help of some of your measures, these measures are working fine in my data model also(and it is pretty fast) but there is the last issue remaining which is similar to the meaure which you've created.
So in this file (which I have shared) there is a meaure for Previous value. Issue is whenever we filter the date using slicer, then at the last row of the visual it is showing blank value (logically it is correct because when filter is applied then, there is not any previous value) but by modifying this measure can we do something to get that previous value also.
I tried your previous measures for this issue but those measure were taking so much time to load, so for now I'm looking for a way to modify this (current) measure so that I can also get previous value for the last row of the table.
Here are some screenshots:
when I am not selecting any date then it is showing previous value like you can see in the below screenshot :
So I just want to know from your expertise can we do some small modification in this measure and rectify this issue ?
If you have any questions feel free to ask 🙂

Hi,
Can you try the below measure?
I am not sure about the performance, but I tried to fix the measure that can show the previous value.
Prev_value_Energy_consum1 =
VAR Index =
MAX ( FloatTable[TagIndex] )
VAR Prev_datetime =
MAXX (
FILTER (
ALL ( FloatTable ),
FloatTable[Date] = MAX ( FloatTable[Date] )
&& FloatTable[Time] < MAX ( FloatTable[Time] )
&& FloatTable[TagIndex] = Index
),
FloatTable[Time]
)
VAR Prev_date =
MAXX (
FILTER (
ALL ( FloatTable ),
FloatTable[Date] < MAX ( FloatTable[Date] )
&& FloatTable[TagIndex] = Index
),
FloatTable[Date]
)
VAR Prev_time =
MAXX (
FILTER (
ALL ( FloatTable ),
FloatTable[Date] = Prev_date
&& FloatTable[TagIndex] = Index
),
FloatTable[Time]
)
RETURN
SWITCH (
TRUE (),
NOT ISBLANK ( Prev_datetime ),
SUMX (
FILTER (
ALL ( FloatTable ),
FloatTable[Time] = Prev_datetime
&& FloatTable[Date] = MAX ( FloatTable[Date] )
&& FloatTable[TagIndex] = Index
),
FloatTable[Val]
),
CALCULATE (
SUMX (
FILTER (
ALL ( FloatTable ),
FloatTable[Time] = Prev_time
&& FloatTable[Date] = Prev_date
&& FloatTable[TagIndex] = Index
),
FloatTable[Val]
)
)
)
