list difference from previous month data
DAXI have a month wise employee data (sample below) and I want to calculate the leavers (removed) and joiners(added) by month. e.g. Jan 2016, I want to know many entries removed and how many new...
In my opinion, you will need some calculcated columns, a calendar table and some measures in this case.
calculated columns
Date = DATE(Entries[Year],Entries[Month],1)
if last month's entry exists =
SWITCH (
TRUE (),
CALCULATE (
VALUES ( Entries[Emp No] ),
FILTER (
ALL ( Entries ),
EARLIER ( Entries[Branch] ) = Entries[Branch]
&& EARLIER ( Entries[Emp No] ) = Entries[Emp No]
&& EARLIER ( Entries[Date] ) = DATEADD ( Entries[Date], +1, MONTH )
)
)
= BLANK (), "N",
"Y"
)Measures
new entries = CALCULATE(COUNTROWS(Entries),Entries[if last month's entry exists]="N") removed entires = COUNTROWS ( FILTER ( ALL ( Entries ), MAX ( 'Calendar'[Date] ) = DATEADD ( Entries[Date], +1, MONTH ) ) ) // last month's entries - ( COUNTROWS ( Entries ) - [new entries] )Check more details in the attached pbix.
