Default values for data before first available date in fact table

Anonymous — Fri, 18 Oct 2024 08:09:12 GMT

Hello,

I have a small chalenge with past dates and values.

In my facts table first sales values start in January 2024. I have actual sales data from Jan till Dec 2024.

In my calendar table and on visuals I will be also displaying data for 2023 although no actuals sales occured in this period and data in facts table is not available.

Is there a way for me to populate with DAX all dates in the past before first sales occured (<Jan 2024) as a default 100 for example?

Thank you for help.

Hi Anonymous ，

try to plot with a measure like below instead:

Measure = IF( SUM([Total Sales]) = BLANK(), 100 )

hello, thanks for you reply.

My case is more complex so I would like to define in DAX a rule related to the dates in the past before sales occured (maybe something with max/min dates) because I need to apply a different rule for blanks in the future. That's why I need to distinguish those 2 cases and I cannot just put blanks everywhere. I need DAX to be more specific to the dates in the past. Thank you.

hi Anonymous ,

try this and what is attached:

Measure = VAR _maxsalesdate = MAXX(ALLSELECTED(data), data[Date]) VAR _minsalesdate = MINX(ALLSELECTED(data), data[Date]) VAR _currentdate = MAX(dates[Date]) VAR _result = SWITCH( TRUE(), _minsalesdate>_currentdate, 100, _maxsalesdate<_currentdate, 1000, SUM(data[Sales]) ) RETURN _result
