When you create a subject area none of the objects appear on the screen Matt Russo Updated March 07, 2018 14:46 Follow Solution: Check on auto-populate in the er_diagram that exists within the new subject area. Figure 1. Figure 2. Figure 3. Related articles I am unable to reverse engineer from a SQL server database. That gives me errors like Statement(s) could not be prepared Invalid object name SYS. table or object. What Problems or Issues are fixed in the various ERwin releases? What is the best practice to quickly move specific tables into one new Diagram and retain the lay out? Also prevent tables /entities from being deleted from the entire model when deleted from a specific Subject Area? Can I use a r9.64 erwin DM with a r9.7 license? What languages erwin Data Modeler support other than English? Comments 0 comments Please sign in to leave a comment.
