Old topic retrieval.
I'm using same process with mpmlink : containers (product & libraries) defined product centric and not per usage. Hierarchy of views design -> manuf & Aftermarket. And also security domains based on foldering for segregating design data and manuf data in each container using the same root foldering structure for all containers ie: design,manuf,aftermarket,sales etc.... I also have sub folders in manuf, 1 per plant. only member of the linked group with domain are able to edit create content for a specific folder. this is also mixed with several conditions based on the type of object, state etc...so In addition for instance we prevent manuf people from seing the "inwork" content in design view. And i have discovered an issue in Windchill10M050 : I face a pb for creating downstreams in mpmlink when exists a latest "in work" version in design view in addition with the previous released ones. Seems mpmlink evaluates user permission on the "source" part (the upstream) using a "retrieve latest version" utility and not the version user has selected and want to create a downstream based on. So my manuf users are receiving a denied permission even if they try to create a downstream from a content they'have an access granted to because mpmlink says they can't access the design view because the version is "inwork".
Heard about a workarounf or knowing anything about the subject someone ?
