We're in the process of removing unwanted units from an OBS. We were able to disassociate most of them from Ideas and Projects Objects (in order to delete), however one last unit remains - UNASSIGNED. Despite there not appearing to be any associations, when we try and delete UNASSIGNED, it states:
Error OBS-0219: You cannot delete an OBS used for datamart processing You must first remove the Datamart association
We have tried running Datamart jobs and also cleared system cache to no avail. How do we identify what's blocking us from deleting this particular unit?
