Do not display records with values to zero, multiple columns

[Syndicate_Admin]

Good.

I have read several related posts, but I can not show only the data that is not at zero, I give the example:

I have two product consumption tables, related to a product table with its code.

I make the total consumption (SUM) and calculate its difference.

When I show the summary, I see values at € 0, I have tried filtering for the difference, but I cannot, since it is the case that some give € 0 as a result.

One may have consumption in one year if and in another not or vice versa

Any ideas? This is the situation I have:

So you do not want to show records where all three columns are zero? Please confirm my understanding.
