Enabling Principal Status of a Condition or Result
A principal is a user or group on My webMethods Server. A business analyst who works with decision tables that were exported from webMethods Rules Development to My webMethods Server repository can assign a principal to a condition or result value. This is only possible if the rules developer annotated the condition or result column as principal when creating the decision table with webMethods Rules Development. The condition or result column must be of data type string, and the condition or result values must not contain parameter elements, actions, constants or functions. Once a condition or result column was annotated principal, you can only assign literal values to the condition and result values.
To annotate a condition or a result as principal:
2. Make sure, the condition or result you want to annotate as principal is of data type string, and the condition or result values do not contain parameter elements, actions, constants or functions.
3. Right-click the respective column header and select 
Enable Principal from the context menu. Note:
You cannot select the Enable Principal item from the context menu, if a data provider service has already been assigned to the condition or result column.
4. Save your changes to the decision table.
