Sharing a temporary table between measures
Hello,
Please can you tell me if it's possible to calculate a temporary table in a measure, and then share that table with other measures (without it having to be calculated each time).
I have 8 columns that all need to calculate the same temporary table and it's taking 50 seconds to run, so I was thinking if the table can be shared that could reduce to about 6 seconds?
Thank you,
CW
The answer is No and Yes
No ... you can not crate a measure in one measure and use it in another. ☹️☹️
But ... yes ... I have a solution to your 50 second problem 😀😀

How it works ...
First use Enter Data to manaully create a driver table with the names of your 8 meaures
For example her are 6 ...
Then create a DAX measure which uses VAR to build your temp table once.
Note it is much faster to aggergate using ADDCOLUMNS rather that SUMMARIZEThen use SWITCH to reuse the temp table 8 times.
Dynamic =VAR salesbycountry = ADDCOLUMNS(VALUES(Customers[Country]),"CSales",[Total Sales],"CCosts",[Total Costs],"CTax",[Total Tax])
RETURN
SWITCH(SELECTEDVALUE(Driver[ID]),1, SUMX(salesbycountry,[CSales]),2, SUMX(salesbycountry,[CSales] + [CTax]),3, SUMX(salesbycountry,[CSales] - [CCosts]))For example this DAX meassure creates salesbycountry temp table.
Then uses salesbycountry to create lossbycountry and profitbycountry temp tables.
Then uses SWITCH to create 6 measure.
This method can easily reduce 90 seconds masures to under 5 seconds.
Please let me know how you get on.
Filtered =VAR salesbycountry = ADDCOLUMNS(VALUES(Customers[Country]),"CSales",[Total Sales],"CCosts",[Total Costs],"CTax",[Total Tax])VAR lossbycountry = FILTER(salesbycountry,[CCosts] > [CSales])VAR profitbycountry = FILTER(salesbycountry,[CSales] >= [CCosts])
RETURN
SWITCH(SELECTEDVALUE(Driver[ID]),1, SUMX(lossbycountry,[CSales]),2, SUMX(lossbycountry,[CSales] + [CTax]),3, SUMX(lossbycountry,[CSales] - [CCosts]),4, SUMX(profitbycountry,[CSales]),5, SUMX(profitbycountry,[CSales] + [CTax]),6, SUMX(profitbycountry,[CSales] - [CCosts]))Thanks for reaching out for help.

PowerWhy Unfortunately measures cannot return tables. I would love that feature. You might be able to increase performance using "horizontal fusion" preview feature in October release. Yet another super useful but forgotten idea:
