In Create SR Page, When a SR is created for a particular SR type. the task gets created after that usually[Tasks are defined in Task Template].
But currently it is taking 10 to 15 minutes to automatically create. During this time, if we try to update sr we get error “You cannot change the owner of this service request because there is an active workflow in progress”.
Solution: Go to Setup Service Requests -> Request Types
Select the service type you are facing problem and you would see that the workflow contains
"@Duplicate Check and Auto Task Create for Web/EMC created SR"
Clear the workflow field and save. Now the issue will not come
