VAR _PreviousMonth = PREVIOUSMONTH('Calendar'[MonthYear])

VAR SalesAmount = CALCULATE(

    SUM(Hashavshvet[sales]),

    FILTER(

        Hashavshvet,

        Hashavshvet[SortCodeName] = "test" &&

        Hashavshvet[FullName] = "meals" &&

        Hashavshvet[AccountKey] = "800" && Hashavshvet[MonthYear] = _PreviousMonth

Hi @SammyBM ,

Here is my sample data:

I don't know if there is a relationship between your Calendar table and the Hashavshvet table, so I used a DAX that works fine with or without the relationship:

salePreviousMonth = 
VAR _PreviousMonth = PREVIOUSMONTH('Calendar'[MonthYear])
VAR SalesAmount = CALCULATE(
    SUM(Hashavshvet[sales]),
    FILTER(
        ALL(Hashavshvet),
        Hashavshvet[SortCodeName] = "test" &&
        Hashavshvet[FullName] = "meals" &&
        Hashavshvet[AccountKey] = "800" && YEAR('Hashavshvet'[MonthYear]) = YEAR(_PreviousMonth) && MONTH('Hashavshvet'[MonthYear]) = MONTH(_PreviousMonth)
    )
)
RETURN SalesAmount

Thanks Dino , Something is weired. I know how to use time intl formulas, But somthing is getting wrong in my DAX  - I've tried your suggsetion ( both calendar and hashavshvet  connected via Date colum. But yet i can get previous month sales - Here my error : 
"... A table of multiple values was suplied where s single value was expected "

Hi @SammyBM - I have tested the sample data, Can you please try below measure and let us know.

salePreviousMonth1 =

CALCULATE(

    SUM(Hashavshvet[sales]),

    PREVIOUSMONTH('Calendar'[MonthYear]),

    Hashavshvet[SortCodeName] = "test",

    Hashavshvet[FullName] = "meals",

    Hashavshvet[AccountKey] = "800"

)

Hope it helps.

Hi @SammyBM -As per above formaule shared, slight modification as below

I hope you already have a calendar table in your model

salePreviousMonth =
VAR _PreviousMonth = PREVIOUSMONTH('Calendar'[Date]) // Assuming 'Date' is your calendar date column
RETURN
CALCULATE(
SUM(Hashavshvet[sales]),
FILTER(
Hashavshvet,
Hashavshvet[SortCodeName] = "test" &&
Hashavshvet[FullName] = "meals" &&
Hashavshvet[AccountKey] = "800" &&
Hashavshvet[Date] IN _PreviousMonth // Ensure that you use the actual date field here
)
)

Hope it works, if still  any please share sample data in text for further analysis.

Thank you for the support !
The calendar table is set by month year interval , as the customer only wants to look on monthly data. so the monthyear is date. 
i've tried your solution but is still bringing blank values.
