Read Only object problem in Creo 4.0 / Windchill 11.0
we recently upgraded from Creo 2.0 to 4.0 and from windchill 10 to 11. Since the switch, when we regenerate an assembly for example, we get the conflict window "Skipped regeneration of Read Only object" on some parts, but not all. These parts are not Read Only, they are not marked as Read Only in the windchill viewer. These parts have not been released either, they are "in work" on windchill. The only way to regenerate these parts are to check them out manually.
Would anyone know how to fix this? I don't want to just hide the conflict message, I want the parts to regenerate.
