A possibility would be helpful to choose specific object attributes / metadata attributes which should be shown to an user in link-tables or search results even if the user has no read access to the object (e.g. object type, object number, organization, origin company, creator).
Benefit 1 - transparency:
User would know that there is an object linked and it is not hidden.
Benefit 2 - no workaround needed, which saves time:
You would not have to create a report which bypasses the ACLs and showing the attributes of the linked objects where the user doesn't have access to in the report result. Creating a report takes time and each time executing the report in such cases to find out the relevant information takes also too much time for the user.
Benefit 3 - user does not have to go the way over the administrator, which saves time:
This would give the user the possibility to contact directly the right person and request access or ask for more information about this object, instead of asking the administrator. If the user would try to open the object, he would receive the error message that he has no access to this object, or, better, in this case you do not offer a link to the object.
Benefit 4 - validations would show meaningful messages:
This would also help to show the relevant information in validations. If a validation is throwing an error for some linked objects but the user doesn't have access to the linked object, it would show the relevant attributes with this requested enhancement. This gives the user the possibility to contact the right person. At the moment it shows for example "Error, please contact your administrator" or a similar message, but no information about which object causes the validation error.
