NETWORKDAYS overriding Variables

To bypass  this issue of inacuracy of NETWORKDAYS at the total line, I came back to the basic,

I skipped the NETWORKDAYS funktion, and count days in a calculated variable table. and chetck that the aggregation worked properly at the end.

Duration in work days from Release date to Last Ship Date2 =

Var selection =

    CALCULATETABLE(

        FACT_CUSTOMER_ORDER_LINE_C,

            FILTER(FACT_CUSTOMER_ORDER_LINE_C ,

                FACT_CUSTOMER_ORDER_LINE_C[Date First Released] <> BLANK()

                && FACT_CUSTOMER_ORDER_LINE_C[Date Last Actual Ship] <> BLANK()

        )

    )

VAR list_with_days =

        ADDCOLUMNS(

             selection   ,

            "duration work days",

            COUNTROWS(

                FILTER(ALL('Calendar'),

                    WEEKDAY('Calendar'[Date],2) <= 5

                    &&  'Calendar'[Date] >=  [Date First Released]

                    &&  'Calendar'[Date] <  [Date Last Actual Ship]

                )

            )

            ,

            "count exception days",

            COUNTROWS(

                FILTER(ALL('Calendar WORK_TIME_EXCEPTION_C'),

                    FACT_CUSTOMER_ORDER_LINE_C[SITE] = 'Calendar WORK_TIME_EXCEPTION_C'[SITE]

                    && [EXCEPTION_DATE] >=  [Date First Released]

                    &&  [EXCEPTION_DATE]  <=  [Date Last Actual Ship]

                )

            )

        )

       

return

CONCATENATEX(list_with_days  ,

    FACT_CUSTOMER_ORDER_LINE_C[Date First Released]   & " to " &  FACT_CUSTOMER_ORDER_LINE_C[Date Last Actual Ship] & " give "  &  [duration work days] -  [count exception days]    , ", " , FACT_CUSTOMER_ORDER_LINE_C[Date First Released] ,ASC

)

 

This new basic approch is much more accurate,

 

I do not know how to reports these bug on NETWORKDAYS to developer team ?
