Scope: managed applications, ordinary applications.
1. With common attributes, you can add attributes for several metadata objects (catalogs, documents, registers, and other) at once to solve any of the two application tasks:
-
To separate data (the Data separation property is Separate).
-
To expand attributes for several objects (the Data separation property is Do not use).
2. Common attributes without data separation are used to add functionality that is not part of business logic of applied objects (for example, that performs configuration tasks in general). However, some data must be stored directly in applied objects (rather than in related registers).
Common attributes cannot be used to easily add similar attributes to applied objects. For example, it is incorrect to add standard document attributes to common attributes, such as Responsible person, Comment, Company, and other. Note that access rights to common attributes are set up separately from the objects they are addded to.
3. Select the common separator sequence order for a metadata tree according to the order required for setting related session parameters.
