Relationship matrix with multiple packages

[martin1]

Hi,
Is it somehow possible to create a relationship matrix in EA which uses a group of packages as source for elements? (to view in the matrix against the target elements)
My initial idea was to create a special SQL query or use the query editor, but until now I was not able to come up with a solution.
Thanks
Martin

Not sure if it helps but you can do matrices across a hierarchy of packages grouped under two for x and y of matrix. Just enable that by selecting hierarchy in matrix

selecting hierarchy in matrix

Where exactly can I find this?
