(Looks like noone else had this request here, therefore I like to add this issue into the Idea portal herewith.)
In PTC Integrity LM (still in 11.1), IBPLs showing items even if the projects where the items beloning to are not accessible from permission point of view.
Having organisation specific data that only the org itself should see in their IBPLs.
But, if no simple constraint can be defined, then ANY item from any organization = project is shown to ANY user.
This is a known issue since years, a corresponding RFC exists. I saw that almost 40 customers are linked to this RFC.
The most obvious solution approach would be a simple check box in the IBPL field saying "Show only items from permitted projects = <yes/no>".
This would solve almost 60% of all setup issues we have in this area.
Furthermore, this easy solution would solve the diffculty we have with the post-fix like , etc. Integrity adds this post-fix automatically in case another organization has also just entered the same summary. This post-fix makes it even more complicated to enter or update data through API or CLI, as we cant forsee which post-fix is added.
