In the above figure, you can see that Source activity is properly that Start Event is not connected with the incoming Source activity and has no outgoing sequence flow but Target and Source activity has no outgoing sequence and End Event has an outgoing sequenceincoming sequence flow. The validation message is displayed in the Alerts Paneloption of the toolbar.

There are two categories of validations:

• BPMN Server Specific Validation: This includes Adeptia Connect Server validations, for example, File Target has no input source stream. This is displayed as "BPMNServer" in the Category column of Alerts Paneloption.
• BPMN Specific Validation: This includes BPMN specific validations, for example, end event cannot have outgoing sequence flow. This is displayed as "BPMN" in the Category column of Alerts Panelof Alerts option.

Validation messages are further divided into two types:

• Error: These are displayed in the Alerts Panel menu with type ( Image RemovedImage Added ) along with error message and the corresponding user action is reverted if possible. If revert action takes place successfully then a warning message is displayed explaining the reason of revert operation. For example, start event cannot have incoming sequence flow, hence removed.
• Warning: These are displayed in the Errors Panel Alerts menu with type ( Image RemovedImage Added ) and the corresponding warning message is displayed. For example, start event has no outgoing sequence flow.
