DAX Formula

[Laman]

Hi! I want to get products which are sold n month sequentially.   i wrote a dax measure , doest give an error but also doesnt works well. Example: if i want to find products which are sold 6  month sequentially, in a result it gives a product whcih are sold 3 month sequentially.

VAR NumberOfMonths = 6

VAR LastNMonths =
DATESINPERIOD(
'Date'[Date],
MAX('Date'[Date]),
-NumberOfMonths,
MONTH
)

VAR SelectedProductIDs =
SUMMARIZE(
FILTER(
'_Measures - Sales Invoice',
'_Measures - Sales Invoice'[SalesInvoiceDateID] IN LastNMonths
),
'_Measures - Sales Invoice'[ProductSID],
"MonthCount", DISTINCTCOUNT('_Measures - Sales Invoice'[SalesInvoiceDateID])
)

VAR ProductsWithSales =
FILTER(
SelectedProductIDs,
[MonthCount] = NumberOfMonths
)

RETURN
IF(
COUNTROWS('_Measures - Sales Invoice') > 0,
1,
0
)

I feel the below revised formula may works

VAR NumberOfMonths = 6

VAR LastNMonths =
DATESINPERIOD(
'Date'[Date],
MAX('Date'[Date]),
-NumberOfMonths,
MONTH
)

VAR SelectedProductIDs =
SUMMARIZE(
FILTER(
'_Measures - Sales Invoice',
'_Measures - Sales Invoice'[SalesInvoiceDateID] IN LastNMonths
),
'_Measures - Sales Invoice'[ProductSID],
"MonthCount", DISTINCTCOUNT('_Measures - Sales Invoice'[SalesInvoiceDateID].[Month])
)

VAR ProductsWithSales =
FILTER(
SelectedProductIDs,
[MonthCount] = NumberOfMonths
)

RETURN
IF(
COUNTROWS(FILTER('_Measures - Sales Invoice', '_Measures - Sales Invoice'[ProductSID] IN ProductsWithSales)) > 0,
1,
0
)

@Laman , Try updating your measure as

VAR NumberOfMonths = 6

VAR LastNMonths =
DATESINPERIOD(
'Date'[Date],
MAX('Date'[Date]),
-NumberOfMonths,
MONTH
)

VAR SalesInLastNMonths =
FILTER(
'_Measures - Sales Invoice',
'_Measures - Sales Invoice'[SalesInvoiceDateID] IN LastNMonths
)

VAR ProductMonthCount =
ADDCOLUMNS(
SUMMARIZE(
SalesInLastNMonths,
'_Measures - Sales Invoice'[ProductSID],
'Date'[YearMonth]
),
"MonthCount", COUNTROWS(SalesInLastNMonths)
)

VAR ProductsWithSalesInAllMonths =
FILTER(
ProductMonthCount,
[MonthCount] = NumberOfMonths
)

RETURN
IF(
COUNTROWS(ProductsWithSalesInAllMonths) > 0,
1,
0
)
