Declare Trigger rules

|
Records can be created in various ways. You can add a new record to your application or copy an existing one. You can specialize existing rules by creating a copy in a specific ruleset, against a different class or (in some cases) with a set of circumstance definitions. You may copy data instances but they do not support specialization as they are not versioned.
Based on your use case, the Create, Save As or Specialization form is used to create the record. The number of fields and available options vary by record type. Start by familiarizing yourself with the generic layout of these forms and their common fields:

Description |
Apply to |
Select a class for this rule. At runtime, a clipboard page of this class must be a top-level page. The properties to be watched may be in this class (or in the class of an embedded page). You cannot use a Rule-Declare-* class or any ancestor of the Rule-Declare- class (including @baseclass) here. You cannot use a class derived from the Code- or Embed- class here. |
Identifier |
Enter a name for this trigger rule. Begin the name with a letter and use only alphanumeric, ampersand, and dash characters. No other rules explicitly reference this Apply to value. However, because of normal class inheritance, a Declare Trigger rule named NewGoldCard at one level in the class structure may override (and so prevent execution of) a Declare Trigger rule named NewGoldCard at a higher level in the class structure. |
