PowerBI Dax Query - To find invoice which never had success state - powerbi

Question

I have to find the count of invoices that never went to a successful state at all. I tried checking multiple sites but not able to understand and recreate the query. Kindly help me. Thanks in advance.
In the above sample invoice 14 never went to success state. So the InvoiceCount = 1 and UniqInvoice count is 2.
I want the uniqInvoice count from the above table.

Answer 1

Create a Custom Column and a Measure as below to achieve your required output-
Custom Column-
success_check =
var current_row_invoice = your_table_name[invoice]
var count_success =
CALCULATE(
COUNT(your_table_name[invoice]),
FILTER(
ALL(your_table_name),
your_table_name[invoice] = current_row_invoice
&& your_table_name[status] = "S"
)
)
RETURN IF(count_success>=1, 1,0)
Measure-
unique_count =
CALCULATE(
DISTINCTCOUNT(your_table_name[uniqinvoice]),
FILTER(
your_table_name,
your_table_name[success_check] = 0
)
)
Here is the output-

I finally found a way to frame the Dax Query, Hoping it will help someone.
FC = CALCULATE (
DISTINCTCOUNT ( InvoiceTable[UniqInvoice] ),
FILTER (
InvoiceTable,
NOT (
InvoiceTable[Invoice]
IN SELECTCOLUMNS (
FILTER (
SUMMARIZE ( InvoiceTable, InvoiceTable[Invoice], InvoiceTable[Status] ),
InvoiceTable[Status] = "S"
),
"InvoiceNo", InvoiceTable[Invoice]
)
)
)
)
