Can i pick the collective PI Square brain on how you have dealt with the modeling in PI AF of Multi-Purpose Units (MPU)?
In a typical S95 asset hierarchy, your units sit nicely in your Production Line. However, a MPU can be used in multiple production lines.
I can think of duplicating, referencing, picking a dominant line, creating functional hierarchies, etc. But i don't really see an advantage of one scenario over the other.
I am slightly inclined to reference the MPU and find some way to avoid rollups when the referenced unit is not active in specific line.
