Hello,
I am currently trying to use DAX to add a TIMEDIFF column based on multiple conditions below:
IF the ID is the same, and the Signifier column has a DSCN value followed by a RECO value on the same day, add a column that subtracts the time difference between those two rows.
For example, since the second row and third row fulfills these conditions, it would subtract 17:17 and 8:31 and add the difference in a new column.
Hi @alexpork
Please always show your sample data in text-tabular format in addition to (or instead of) the screen captures. A screen cap doesn't allow people to readily copy the data and run a quick test and thus decreases the likelihood of your question being answered. Just use 'Copy table' in Power BI and paste it here.
Create a new calculated column in your table:
New column =
IF (
Table1[Signifier] = "RECO",
VAR previousRowInDay_ =
CALCULATETABLE (
ROW (
"Signifier_", MAX ( Table1[Signifier] ),
"DateTime_", MAX ( Table1[DateTime] )
),
ALLEXCEPT ( Table1, Table1[ID] ),
INT ( Table1[DateTime] ) = INT ( EARLIER ( Table1[DateTime] ) ),
Table1[DateTime] < EARLIER ( Table1[DateTime] )
)
VAR isDSCN_ = MAXX ( previousRowInDay_, [Signifier_] ) = "DSCN"
VAR previousTimeInDay_ = MAXX ( previousRowInDay_, [DateTime_] )
VAR diffInMins_ = IF ( isDSCN_, ( Table1[DateTime] - previousTimeInDay_ ) * 24 * 60 )
// Time difference converted to minutes. Update if another unit required
RETURN
diffInMins_
)
Please mark the question solved when done and consider giving a thumbs up if posts are helpful.
