ALV average calculation without considering blank or zeroed row cells

Hello all,

I have na issue about ALV field catalog which I could not find the answer.

I need an alv average subtotal considering only row cells which are not blank or zeroed.

In the Picture below the average is 6,25 because it is considering the blank/zero row cells.

I need an average calculation without considering the blank rows which should be 10,41.

I have used the fieldcatalog-DO_SUM = 'C' and also fieldcatalog-nozero = 'X' which I thought it could solve the issue (but it did not, the average still consider the blank cells for calculation)

I cannot just simply avoid these zeroed/blanked rows because there is other necessary data in the other row cells.

So, my question: is there any field catalog properties to calculate the average without considering the row blank/zeroed cells or, it is necessary

to code manually this average calculation in a summary row in the internal alv output table in order to achieve that ?

If there is anybody there who ever faced this issue and could help, please explain how.

Thanks.
