I have a little problem with calculating a certain batch characteristic.
The situation is the following:
I have batch char A, batch char B and batch char C. Batch char C is the result of the sommation of char A and B. The problem I have now is that batch char C only should be calculated when batch char A and B are different from 0.
I have a custom build interface that imports QM data to the batch chars. Default, all my batch chars are set to 0 so if I just say $self.charC = $self.charA + $self.charB, I always get a value.
Is it possible to some sort of IF statement to check if the value is different from 0?
