Hi All,
I am doing a headcount report and would like to use the SamePeriodLastYear function to calculate last year headcount, however, the results are wrong and the numbers look strange. Any ideas?
@Anonymous
In the Table Visual, are you using the Month column from Calendar table?
i am using the "Month" in Calender table as the row content.
Hi @Anonymous,
Have you solved your problem?

Hi @Anonymous,
If it is convenient, could you share your data model so that I can test with your scenario.

Hi @Anonymous,
What about use the formula below?
py =
CALCULATE (
SUM ( 'Table1'[Headcount] ),
FILTER ( 'Table', YEAR ( 'Table'[Date] ) = YEAR ( MAX ( 'Table'[Date] ) ) - 1 )
)
Here is the output.
If you still want to use Time Intelligence functions for your case, please share some data sample and the relationship between the tables.
Best Regards,
Cherry
