# Empty value as a result of an if then else calculation

I have a have a simple calculation: "if sum(0, 0, m1) <= 0 then -1 else sum(0, 0, m1)"

Instead of the value "-1" I would like to have the value NULL (empty). Is it possible to do that?

0

Marlene KnaupI think

textlike "NULL" is not possible in a measure column.But instead you could make your calculation and after that you can hide the value with the visibility agent.

Flemming Hjerrild KristensenThanks - visibility agents can only partly solve my problem (a complex analysis ;-))

I don't need a text like "NULL" - I need the measure to be empty like marked below, when the value is O or less:

Louise Stub HansenI would have suggested a visibility agent as well :-)

Can you explain why a visibility agent with syntax <= 0 can't do the job?

Ole DyringHi Flemming,

I have an idea related to number formatting. Not sure it will work in your case, but here it is.

First, you should change your calculation to this:

if sum(0, 0, m1) <= 0 then

0else sum(0, 0, m1)Secondly, you can work with Number formatting, where zero numbers can be set to no digits. With no digits, it will turn up as a blank instead of '0':

It did some of the work.

But I have a calulation counting the number of Customers (with a turnover above 0) and this calculation still count Customers with the hidden zero value (the first column R12M only have 28 customers but the total of buying customers is 29)

Ole DyringHi Flemming,

I guess you will need to insert an extra calculation (as a new measure, m3):

Then you Number of Buying Customers can be calculated as:

Of Course - why coundn't I see that myself ;-)

Thanks

Martin HlawatschHi there,

I have a KPI that I want to hide, if the value it is supposed to show is empty or shows an error. I tried the trick, but eventhough the value is hidden and the option "hide if empty" is marked, the KPI is still showing. Is there another workaround?

Thomas PHi Flemming

Have you been able to solve your problem with "empty" instead of the value "0"?

I have the same problem with a targit-measure. Have been using PowerBI earlier, where the problem was easy to solve with just typing "".
