    Hi Anonymous ,

    It's my pleasure!

    You can create another calculated column.

    Last month value =
MAXX (
    FILTER (
        'Table',
        'Table'[Record ID] = EARLIER ( 'Table'[Record ID] )
            && MONTH ( 'Table'[Month] )
                = MONTH ( EARLIER ( 'Table'[Month] ) ) - 1
    ),
    'Table'[Value]
)

    Result:

    I attach my sample below for your reference.

v-yanjiang-msft - Looking for a bit more advice on this!

 

The code provided seems to work however as its based on Months only, in January (01) its not finding December (12) as i think the formula is looking at month number only.

 

Is there any way of expanding this to work for Year as well?

 

Thanks!
