# Query definition - exclusion of calculated formulas

Hello

I have a formula 1 and a formula 2.

Let's say formula 1 has the result 1 = 100

On the other hand formula 2 has the result 2 = 30.

Another formula 3 subtracts the values of both formulas, 1 and 2, result 3 = 70.

Another example:

Formula 1, result 1 = 100

Formula 2, result 2 = ' '

As we can see, result 2 has no values as there are no records available in the InfoCube.

Now I would like to calculate formula 3 in the way, that this constellation of result 1 (=100) and result 2 (=' ') is ignored. That means there should be NO value be calculated for result 3.

How can this be achieved?

Regards
