Default values for data before first available date in fact table

[BI_Samurai]

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.

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 @BI_Samurai ,

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

Hi @BI_Samurai ，

try to plot with a measure like below instead:

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