Hi,

I'd like to remove weekend days from calculating on time data. For example - 2 day turnaround to be met. Issued on Mon but started on Friday so would meet target but at moment is looking like 3 days. Could anyone help me with a beastmode for doing this - I have an opened and closed date.

Thanks,

Katie

If you wanted to do it in a beast mode, it is quite a bit more involved, but you could do this:

CASE WHEN 
`Start Date` = `End Date` THEN 0 
ELSE
DATEDIFF(
CASE WHEN DAYOFWEEK(`End Date`) = 7 THEN SUBDATE(`End Date`, INTERVAL 1 DAY)
WHEN DAYOFWEEK(`End Date`) = 1 THEN SUBDATE(`End Date`, INTERVAL 2 DAY) ELSE `End Date` END
,
CASE WHEN DAYOFWEEK(`Start Date`) = 1 THEN ADDDATE(`Start Date`,INTERVAL 1 DAY)
WHEN DAYOFWEEK(`Start Date`) = 7 THEN ADDDATE(`Start Date`,INTERVAL 2 DAY) ELSE `Start Date` END
) 
-
((CASE WHEN WEEK(CASE WHEN DAYOFWEEK(`Start Date`) = 1 THEN ADDDATE(`Start Date`,INTERVAL 1 DAY)
WHEN DAYOFWEEK(`Start Date`) = 7 THEN ADDDATE(`Start Date`,INTERVAL 2 DAY) ELSE `Start Date` END) = WEEK(CASE WHEN DAYOFWEEK(`End Date`) = 7 THEN SUBDATE(`End Date`, INTERVAL 1 DAY)
WHEN DAYOFWEEK(`End Date`) = 1 THEN SUBDATE(`End Date`, INTERVAL 2 DAY) ELSE `End Date` END) THEN 0 ELSE WEEK(CASE WHEN DAYOFWEEK(`End Date`) = 7 THEN SUBDATE(`End Date`, INTERVAL 1 DAY)
WHEN DAYOFWEEK(`End Date`) = 1 THEN SUBDATE(`End Date`, INTERVAL 2 DAY) ELSE `End Date` END) END

-
CASE WHEN WEEK(CASE WHEN DAYOFWEEK(`Start Date`) = 1 THEN ADDDATE(`Start Date`,INTERVAL 1 DAY)
WHEN DAYOFWEEK(`Start Date`) = 7 THEN ADDDATE(`Start Date`,INTERVAL 2 DAY) ELSE `Start Date` END) = WEEK(CASE WHEN DAYOFWEEK(`End Date`) = 7 THEN SUBDATE(`End Date`, INTERVAL 1 DAY)
WHEN DAYOFWEEK(`End Date`) = 1 THEN SUBDATE(`End Date`, INTERVAL 2 DAY) ELSE `End Date` END) THEN 0 ELSE WEEK(CASE WHEN DAYOFWEEK(`Start Date`) = 1 THEN ADDDATE(`Start Date`,INTERVAL 1 DAY)
WHEN DAYOFWEEK(`Start Date`) = 7 THEN ADDDATE(`Start Date`,INTERVAL 2 DAY) ELSE `Start Date` END) END) * 2)
END

If you are able to do it in Magic ETL, the date operations tile makes it quite easy to do.

Magic ETL

Connect your Input DatSet tile to a Date Operations tile.
Configure the tile as shown here:

Note: In Step 4, you will want to make sure to choose your end date first and then your start date as this function subtracts the dates from each other. If you enter the start date first it will result in a negative number.

The results will look like this:
