Formatting a DATEDIFF (DAY & MINUTE) Column

Hi,

I am trying to create a Measure that will provide the format as below:

xD  xH  xM   --->  (D=days, H=hours, M=minutes)

I have two DATEDIFF columns, one providing calculation in DAYS and other in MINUTES.  Some of the DATEDIFF are going to calculate a NEGATIVE duration.  That is what I am trying to format in a understandable way.  Everything I have tried is not showing correct values.

I basically need the value to calculate the same way for NEGATIVE duration as it does for POSITIVE duration.  For some reason, the NEGATIVE duration is not right.

I have attached a sample data file.  Any help would be appreciated.

file is .xlsx, but I am doing this in .pbix
