Double headings issue

[olofu]

Hello,

i'm trying to replicate a matrix from a file to another but I cannot do it.

This is the reference:

I also tried to remove and re-add the field "tipofattprev" in the same file but the results become this and i cannot restore double headers:

How can I do?

Thank you in advance

Hi @olofu ,

When you have a matrix with an hierarchy you have an option on top that you can select the drill down based on rows or columns you need to select it and then you make the drill down and have the double header:
