Hi Team,
Customer is using Parent& child model and only childs will have relationships. When they are logging timeline entries under Relationship, it is directly logging under Child company, not on the Parent company.
Tried this scenario in local, could see same behaviour.
As a workaround, we have suggested to use Associated records option (Associate both Parent company and Relationship at Child company), but as it needs to do manually, customer is looking to show the entries automatically in the way Relationship entries logging automatically under child company.
