Physical name
(Read only.) If the name of the table on the database is longer than 128 characters, the value is entered by the Reverse Data Engineer from the database. In that case, the name of the table in the model is the first 128 characters of the physical name.
System Architect maintains several properties in the table definition that are read‑only in the Table definition dialog, and others that are not visible; the values of all of them are available in a report:
Database name (read only in table definition dialog)
Project Data Model (read only in table definition dialog)
