Business Day Add Using Date Table

Hello

 

Looking for some helpful dax. I need to return a date that is 30 business days from a known date. 

 

I have two tables in my datasource. Table1 is my main data and i'm using an 'OpenDate' as the base/known date.

Table2 is my date table which does contain a 1 or a 0 for business day flag.  This flag is purpose built and has all public holidays and non-working days built into it's logic. 

 

Table2 is joined to the datasource and connected to Table1.[OpenDate].

 

I need to use that column to project 30 days from Table1.[OpenDate].

 

I cannot attach a file due to sensativity. Can anyone help?

hi @Anonymous

 

here is an idea how you could try to solve the problem:

- have a serial numbering for only business days (I used RANKX to create a new table, but maybe you have better options?)
- adding a new column that searches for the business day which is 30 ranks higher

After 30 Business Days = 
var currentRank =  DatesRankedByDay[Rank]
var found = calculate( min(DatesRankedByDay[Date]); All(DatesRankedByDay); DatesRankedByDay[Rank] - currentRank = 30)
return found 


seems to work ...

Thanks DaFloDo, i'm not sure how to create the RankX table. 

 

Do you think there's a way to use a dateadd function with a condition where the business day flag is 1?

Hi @Anonymous,

 

i added the rank by creating a new calculated table by adding the rank as a new column.

DatesRankedByDay = ADDCOLUMNS(FILTER(All(Dates), Dates[IsBusinessday]=True), "Rank", RANKX( FILTER(All(Dates), Dates[IsBusinessday]=True), Dates[Date],,ASC))  

I am sorry, I could not solve the problem without the help of this additional column.

 

best regards

Thanks @DaFloDo, can you clarify - should i be creating a new column in the date table with this code, or, should i be choosing 'new table' and then using this code. 

 

When i add this as a new column in the Dim_Date, this is the error i get:

The expression refers to multiple columns. Multiple columns cannot be converted to a scalar value.

 

 

When i choose new table the error is this:

"This expression refers to a Column object named 'Dim_Date[DatesRankedByDay]', which has an error."

 

DatesRankedByDay = 
ADDCOLUMNS(FILTER(All(Dim_Date),
 Dim_Date[BusinessDayFlag]= True), 
"Rank", RANKX( FILTER(All(Dim_Date)
, Dim_Date[BusinessDayFlag]= True)
, Dim_Date[FullDate],,ASC))  

hi @Anonymous,

 

this will be a new calculated table. please see the attached file.

 

https://www.dropbox.com/s/8sqtl08qu5onshn/after%2030%20days%20budiness%20days%20%28ranked%20dates%29.pbix?dl=1

 

 

to clear things out: 
first step is to create the new calculated table ranked by business days

DatesRankedByDay = ADDCOLUMNS(FILTER(All(Dates), Dates[IsBusinessday]=True), "Rank", RANKX( FILTER(All(Dates), Dates[IsBusinessday]=True), Dates[Date],,ASC))  

second step was adding a new calculated column to the peviously created table

After 30 Business Days = 
var currentRank =  DatesRankedByDay[Rank]
var found = calculate( min(DatesRankedByDay[Date]); All(DatesRankedByDay); DatesRankedByDay[Rank] - currentRank = 30)
return found

Hi,

 

Have you seen the NEXTDAY function? You could use this function inconjuction with your flag. You will need to add some logic to skip the "0" dates.

 

 =CALCULATE(SUM(InternetSales_USD[SalesAmount_USD]), NEXTDAY('DateTime'[DateKey]))

Thanks Garry. I can't really put that solution together with my problem.
