• Right click on the table or view from which the ECT is to be based.
  • Based on your needs, choose from the items in the dropdown:
  • Create All Operations (Read/List/Create/Update/Delete/New Association), however, this is only if you want the end user to have a great deal of control on items in the database
  • New Read Item Operation
  • New Read List Operation
  • New Create Operation
  • New Update Operation
  • New Delete Operation
  • New Association
• The base operations required are Read Item and Read List

    • The checkbox next to the field name controls whether or not this field is visible in the final list.
