In Collaboration Hub, the breadcrumbs for sub-process which has multiple parent process shows only 1 parent despite how user reached the process.
Image/data in this KBA is from SAP internal systems, sample data, or demo systems. Any resemblance to real data is purely coincidental.
The "breadcrumbs" are not designed as a path of navigation back tracking the users interaction following the links down.
Instead the feature is designed to show the shortest path up to a Value Chain following the links form within the models. The shortest path is the main feature. This could be contradicting with the actual links followed by the users interaction. If there are multiple shortest path, the system will choose just one to display.
This feature will not be changed in the old hub.
However in the Velocity Hub, we have a different feature, that shows all parents of the current model, but just on the next level.
