Fill Future Dates in Date Dimension Table and then filter using 3rd Dimension Table

Hello,   I have a problem where I am trying to fill the most recent values from a Fact Table (Fact_BackupStorage_Data) to all dates in my Date table (DIM_Date), and then filter out a number of rows...

    Hi Anonymous 

    I have a test in your sample. Please try this code.

    M_Capacity = 
VAR _LASTDATE = CALCULATE(MAX(FACT_BackupStorage_Data[Date]),ALL(FACT_BackupStorage_Data))
VAR _LASTCAPACITY = CALCULATE(SUM(FACT_BackupStorage_Data[Capacity]),FILTER(ALL(FACT_BackupStorage_Data),FACT_BackupStorage_Data[Date] = _LASTDATE))
VAR _FirstEOLDate = MIN(DIM_BackupStorage_Nodes[EOL Date])
VAR _FirstEOLHOST = CALCULATE(MAX(DIM_BackupStorage_Nodes[Host]),FILTER(ALL(DIM_BackupStorage_Nodes),DIM_BackupStorage_Nodes[EOL Date] = _FirstEOLDate))
VAR _CAPACITYAFTEREOL = CALCULATE(SUM(FACT_BackupStorage_Data[Capacity]),FILTER(ALL(FACT_BackupStorage_Data),AND(FACT_BackupStorage_Data[Date] = _LASTDATE,FACT_BackupStorage_Data[Host]<>_FirstEOLHOST)))
VAR _IF = IF(MAX(DIM_Date[Date])<=_LASTDATE,SUM(FACT_BackupStorage_Data[Capacity]),IF(MAX(DIM_Date[Date])<_FirstEOLDate,_LASTCAPACITY,_CAPACITYAFTEREOL))
VAR _RESULT = IF(_IF = BLANK(),BLANK(),_IF&""&"GB")
RETURN
_RESULT

    Result is as below.

Anonymous , You should not join two dimensions. so Date should not join with DIM_BackupStorage_Nodes .

 

You can use the date range from slicer as filter in the measures you need to filter date from DIM_BackupStorage_Nodes 

 

measures  =

=
var _max = maxx(allselected('Date'), 'Date'[Date])
var _min = maxx(allselected('Date'), 'Date'[Date])
return

calculate (countrows(FACT_BackupStorage_Data ), filter( DIM_BackupStorage_Nodes , DIM_BackupStorage_Nodes [EOL] >=_min  && DIM_BackupStorage_Nodes [EOL] <= _max))

 

If needed, use all(Date) remove the filter from fact(that should be active), or use crossfilter for that.

 

You can keep both joins inactive and try userelationship as per need

    Hi amitchandak 

     

    Thanks so much for taking the time to reply.

     

    I've attempted using the measure you applied above, but unfortunately was not successful. The measure shows only blanks when I create a table with the Date from the DIM_Date table and your measure.

     

    I think I understand the concept of your measure, it's taking all selected dates from date dimension, giving me the value in the first stage of the calculate step, and then filtering it by dates when they are greater than the earliest EOL date.

     

    I'm confused as to why it's not showing any values, as to me that logic makes sense. I've attached a screenshot below, and a scrubbed PBIX file, if you could point me to where I've gone wrong, it would be much appreciated! I have used CrossFilter / UseRelationship before, but not sure where I would apply them here.

        Hi Anonymous 

         

        Thank you so much! That's working perfectly after having applied it to my real dataset also.

         

        Really appreciate the help!

         

        Kind regards

        Andy
