I am testing 4.11.3 and 4.12.0beta. My production database is 4.8.1.
I have some lot controlled items with four levels.
Looking at lot history, the trace is only going down one level in the new versions.
Even if I query a middle level item, the trace will only go forward or backward one level.
The screenshots show the history of the same lot in 4.8.1 and 4.12.0beta.
I have the same issue in 4.11.3
