Modify an ERD record

Applies to User Roles:

System Administrator

An Entity Relationship Diagram (ERD) is a graphic description of the logical structure of a database. Database administrators often rely on conceptual and physical data models to understand the relationships among tables, records, and data, and to produce reports.

To modify an ERD record using the Entity Relationship Diagram (ERD) Creation utility:

  1. Click Tailoring > Tailoring Tools > ERD Create Records.
  2. To locate an existing ERD record, click Search.
  3. Select a record from the record list.
  4. Click More or the More Actions icon, and choose Add Files for Module.
  5. From the More Actions menu, choose Add Master Links.
  6. From the More Actions menu, and choose Add all Related Links.
  7. Click Save.
  8. Click OK.


  • You can add relationships manually from the Manual Relationships tab. Use this tab to define relationships that do not occur in any of the automatically discovered categories. Each relationship that you create manually also appears in the ERD record.
  • The ERD record creation process will fail if the name of the ERD record is not associated with one or more Data Policy records.
