Overview
A decision table represents decision logic which can be depicted as a table. It consists of inputs, outputs and rules.
A decision table is represented by a decisionTable
element inside a
decision
XML element.

Decision name
The name describes the decision for which the decision table provides the decision logic. It is set as the name
attribute on the decision
element. It can be changed via the Properties Panel after selecting the respective
"Decision" in the Decision Requirements Diagram view.
<decision id="dish" name="Dish">
<decisionTable id="decisionTable">
<!-- ... -->
</decisionTable>
</decision>
Decision id
The id is the technical identifier of the decision. It is set in the id
attribute on the decision
element. Just as the name
, the id
can be changed via the Properties Panel after
selecting the respective "Decision" in the Decision Requirements Diagram view.
Each decision should have an unique id when it is deployed to Camunda.
The decision id may not contain any special characters or symbols (e.g. whitespace, dashes, etc.).
The decision id can be any alphanumeric string including the _
symbol. For a combination of words, it's recommended to
use the camelCase
or the snake_case
format. The kebab-case
format is not allowed because it contains the
operator -
.
If the decision id contain a special character or symbol then the decision result can't be accessed in a dependent decision.
