Add a filter to a DAX inside a define

You already have a similar filter on the department :

DEFINE

    VAR __DS0Core =

        SUMMARIZECOLUMNS (

            'Employees'[Matri],
			'Employees'[SDAP type],
			'Employees'[Recorded communications],
			'Department'[Label]

        )

 

EVALUATE

FILTER (

    ADDCOLUMNS (

        __DS0Core,

        "AP_SUV_not_Recorded",

            IF (

                (

                    NOT ( ISBLANK ( 'Employees'[SDAP type] ) )

                        || 'Employees'[SBSDAP type] = "ABC"

                        || 'Employees'[SBSDAP type] = "BB"

                )

                    && 'Employees'[Recorded communications] = "No",

                1,

                0

            )

    ),

    'Department'[Label] = "HR" ,
    'Employees'[Matri] =9999

)

ORDER BY

    'Employees'[Matri] DESC,

    

This is an improved version :

DEFINE
    VAR __DS0Core =
        SUMMARIZECOLUMNS (
            'Employees'[Matri],
            'Employees'[SDAP type],
            'Employees'[Recorded communications],
            'Department'[Label]
        )

EVALUATE
VAR FilteredData =
    FILTER (
        __DS0Core,
        'Department'[Label] = "HR" &&
        'Employees'[Matri] = 9999
    )

VAR Result =
    ADDCOLUMNS (
        FilteredData,
        "AP_SUV_not_Recorded",
        IF (
            (
                NOT ( ISBLANK ( 'Employees'[SDAP type] ) ) ||
                'Employees'[SDAP type] = "ABC" ||
                'Employees'[SDAP type] = "BB"
            ) &&
            'Employees'[Recorded communications] = "No",
            1,
            0
        )
    )

RETURN
    Result
ORDER BY
    'Employees'[Matri] DESC
