Hi Boris,
a) You define an attribute Package Code as String and you specify a default value. Enter the value, example CUSTOMER directly in the Default value field.
b) You indicate that the new attribute should be displayed on the General tab of the entity object
c) To generate a Package list dynamically enter this GTL code.
d) You can see the result. The default is CUSTOMER and you can see all others packages names
Note : I wish to inform you that you can move your entities under packages. So you'd be able to view the list of entities under each of the packages. I do not understand too the need for your request. Why do you want add a new fied to associate packages to entities?
