Validation while Modeling SERVER | DATA CENTER Cloud

|Since 3.14.0-ENTERPRISE.|

Automated diagram validation helps you to keep process models consistent and at a uniform quality level even with a large number of different authors. If diagram validation is activated, the process diagram is continuously checked for certain quality criteria during editing. Opportunities for improvement are then displayed directly on the respective process element. The easy to understand messages enable even inexperienced modelers to design easily understandable and valid process diagrams. However, the implementation of the improvement suggestions is never obligatory. Thus, diagrams can be saved at any time, even in spite of quality issues.

 

To activate the diagram validator, click View → Diagram Validator, or the shortcut icon in the menu bar.

 

 

Diagram validation continuously checks the process model for the following rules:

Rule Configuration per Space SERVER | DATA CENTER

|Since 3.23.0-ENTERPRISE.|  

As a Confluence space administrator, you are able to decide which validation rules you want to be evaluated, and which ones you want to ignore. You have the option to set the notification level for each rule individually, choosing between 'Error', 'Warning' or 'off'.

For each space individually, you can open the space configuration and select the BPMN Modeler Enterprise in the 'Apps' tab. Then you can set for each rule the validation level.
