Shifted Start Date with Year to Date Since Inception

[Anonymous]

Hi all,

I'm new to Power BI and am trying to transform date data (sourced from SQL Server) according to the shift scheme we use. For propery reporting to my users, I need to determine which shift data falls into, and usually only report data for the current shift. The logic below has worked for me in SQL but I am pretty lost in where to begin with Power BI. I don't see how I can use the standard features of columns with "IF" kind of logic. Can anyone point me in the right direction?

>If the timestamp's hour is midnight through 3am, then the shift date is "date - 1" (2nd shift runs 6pm - 3am so Wednesday 2am is really part of Tuesday 2nd shift)

>If the hour is 6am - 5pm, then shift = 1st. If the hour is 6pm - 3am, then shift = 2nd.

>If the timestamp is within the last 8 hours & the shift = shift determined from current time, then current shift = true.

Hi @Anonymous ,

I share a sample measure formula to mark your shift date and index, you can try it if it works on your side:

Shift Index =
VAR _currDate =
    MAX ( Table[timestamp] )
VAR _shiftIndex =
    IF ( HOUR ( _currDate ) >= 6 && HOUR ( _currDate ) <= 17, "1st", "2nd" )
VAR _shitfDate =
    IF ( HOUR ( _currDate ) <= 3, _currDate - 1, _currDate )
RETURN
    _shitfDate & " " & _shiftIndex

I'm not so clarify for your condition #3, can you please explain more about this?
In addition, if above not help, please provide some sample data to help us clarify your data structure and test to coding formula.
