Calculated Column in DAX, if no value then...

[Applicable88]

Hello,

I have a table which mostly has no dataset at the very beginning of the month. Thats because its a forecast sales data for current month, which will be known some time in the first days of a month.

So this table has no rows by then. So I wanted a card to display "TBA"= To be announced, instead of "empty" which is default behaviour from PowerBi Card visualization. 

I did following for calculated column:  

if (  isblank( 'sales'[Forecast]), "TBA", 'sales'[Forecast]) 

also tried with = blank() and other functions. Simply not working. Does DAX won't create a empty row with just a new column stating TBA, because the table has no rows? 

Thank you in advance.

Best.

Hi @Applicable88 ,

If your data model does not have any data, it will not be displayed if you add a calculated column, you can use a measure instead.

@Applicable88 ,

This can work if you can format 'sales'[Forecast] as text

new measures  ---

Forecast M = Sum('sales'['sales'[Forecast])

final measure =

if ( isblank( [Forecast M]), "TBA", [Forecast M] & "")

or better format the number using the format function

Hello @amitchandak ,

not working. 

I think if there are no rows input into DataModell, the format () cannot format from "nothing" and also isblank cannot check for blank when rows=0. Thats what is stated in the left bottom side. zero rows.
