When you create a subject area none of the objects appear on the screen Matt Russo Updated August 02, 2018 18:05 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 Why when I work in erwin r9.8 I consistently receive an error message, "encountered an improper argument" when resizing the window, or clicking on the tabs, Defaults, Entities, Attributes, etc.? Query for Subject Area Name and Table and Column Properties 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? Comments 0 comments Please sign in to leave a comment.
