Power BI Year Over Year analysis using the matrix visual

Hi LondiweNkosi,
Thanks for reaching fabric community, You can perform below steps to calculate %chnage by selecting the slicers.

1) Relationship should be like between your sales and date table.

2) Create measures

- GP = SUM ( SalesData[GP] )

3) Matrix visual format should be like this

Just want to conform you need YOY % chnage is that correct?
Please consider as an accepted solution if helps or give some kudos.

sample table I created

SalesData = 
DATATABLE (
    "Customer", STRING,
    "Date", DATETIME,
    "GP", INTEGER,
    {
        { "DTX", "2023-03-01", 1825000 },
        { "DTX", "2024-03-01", 1745623 },

        { "Ftech", "2023-03-01", 2325460 },
        { "Ftech", "2024-03-01", 1014587 },

        { "Clicks", "2023-03-01", 985625 },
        { "Clicks", "2024-03-01", 1003265 },

        { "Joe Soap", "2023-03-01", 114522 },
        { "Joe Soap", "2024-03-01", 256341 }
    }
)

Date = 
ADDCOLUMNS (
    CALENDAR ( DATE ( 2023, 1, 1 ), DATE ( 2024, 12, 31 ) ),
    "Year", YEAR ( [Date] ),
    "Month Name", FORMAT ( [Date], "MMM" ),
    "Month Number", MONTH ( [Date] ),
    "Year Month", FORMAT ( [Date], "MMM yyyy" )
)
