An application version cannot be saved if an application architect is updating the blueprint or a deployer is deploying the application in one session and another application architect is attempting to update and save the same application blueprint in a different session.
An error message appears when an application architect tries to modify and save an application blueprint.
Could not save Application version because another session has modified it.
While an application architect is saving an application blueprint or a deployer is deploying an application, if another application architect attempts to access the same blueprint, the error message appears in the browser of the second application architect.
Refreshing the application blueprint might cause you to lose the current changes made to the blueprint.
