Add number of working days to a start date

[frankhofmans]

hi PBI experts,

i have the following case:

We have a KPI for the production time of our products (A, B, C) and regions (Europe, North America, Asia). The production time of product A in region Europe may take 2 working days, weekend days not included. we have a KPI file and a production file:

KPI file:

Production type	Region	KPI working days	Key
A	Europe	2	A/Europe
A	North America	4	A/North America
A	Asia	3	A/Asia
B	Europe	7	B/Europe
B	North America	11	B/North America
B	Asia	9	B/Asia
C	Europe	20	C/Europe
C	North America	30	C/North America
C	Asia	27	C/Asia

Production file:

Product type	Region	Date Start Production	Weekday	KPI	Date End Production
A	Europe	3-1-2020	Friday	2	6-1-2020
A	North America	1-1-2020	Wednesday	4	6-1-2020
A	Asia	7-1-2020	Tuesday	3	9-1-2020
B	Europe	9-1-2020	Thirsday	3	13-1-2020
B	North America	5-1-2020	Sunday	5	10-1-2020
B	Asia	5-3-2020	Thirsday	4	10-3-2020
C	Europe	27-2-2020	Thirsday	4	3-3-2020
C	North America	1-4-2020	Wednesday	6	8-4-2020
C	Asia	3-4-2020	Friday	5	9-4-2020
A	Europe	10-4-2020	Friday	2	13-4-2020
A	North America	20-4-2020	Monday	4	23-4-2020
A	Asia	3-5-2020	Sunday	3	6-5-2020
B	Europe	7-5-2020	Thirsday	3	11-5-2020
B	North America	13-5-2020	Wednesday	5	19-5-2020
B	Asia	5-6-2020	Friday	4	10-6-2020
C	Europe	11-6-2020	Thirsday	4	16-6-2020
C	North America	20-6-2020	Saturday	6	29-6-2020
C	Asia	30-6-2020	Tuesday	5	6-7-2020
A	Europe	1-7-2020	Wednesday	2	2-7-2020
A	North America	10-7-2020	Friday	4	15-7-2020
A	Asia	13-7-2020	Monday	3	15-7-2020
B	Europe	15-6-2020	Monday	3	17-6-2020
B	North America	1-7-2020	Wednesday	5	7-7-2020
B	Asia	1-8-2020	Saturday	3	5-8-2020
C	Europe	10-8-2020	Monday	4	13-8-2020
C	North America	20-8-2020	Thirsday	6	27-8-2020
C	Asia	3-8-2020	Monday	5	7-8-2020

The column date end production is the needed outcome (start date + KPI working days). If the production of type A in Europa starts on monday, the production has to be finished on tuesday. If the production starts on saturday, the production also has to be finished on tuesday. 

I hope someone can help me with this problem.

Thanks in advance,

Regards, Frank

Hi @frankhofmans ,

I referred to the link posted by @amitchandak .

1.Create a calendar table.

Date = 
ADDCOLUMNS (
    CALENDAR ( DATE ( 2020, 1, 1 ), DATE ( 2020, 8, 28 ) ),
    "Work Day", IF ( WEEKDAY ( [Date], 2 ) >= 6, 0, 1 ),
    "Work Date", IF ( WEEKDAY ( [Date], 2 ) >= 6, BLANK (), [Date] )
)

Work Date Cont =
IF (
    [Work Day] = 0,
    MAXX (
        FILTER (
            'Date',
            [Date] < EARLIER ( [Date] )
                && [Work Day] <> EARLIER ( [Work Day] )
        ),
        [Date]
    ),
    [Date]
)

Work Date cont Rank =
RANKX ( ALL ( 'Date' ), [Work Date Cont],, ASC, DENSE )

2.Create a calculated column.

DateEndProduction = 
VAR _rank =
    RELATED ( 'Date'[Work Date cont Rank])
VAR _kpi = 'Production'[KPI]
RETURN
    SWITCH (
        TRUE (),
        WEEKDAY ( 'Production'[Date Start Production], 2 ) = 6
            || WEEKDAY ( 'Production'[Date Start Production], 2 ) = 7,
            CALCULATE (
                MIN ( 'Date'[Date] ),
                FILTER ( ALL ( 'Date' ), 'Date'[Work Date cont Rank] = _rank + _kpi )
            ),
        WEEKDAY ( 'Production'[Date Start Production], 2 ) <= 5,
            CALCULATE (
                MIN ( 'Date'[Date] ),
                FILTER ( ALL ( 'Date' ), 'Date'[Work Date cont Rank] = _rank + _kpi - 1 )
            )
    )
