Error “Task – XXXXX: Deactivated task. Use is prohibited” in Scheduled invoice generated process for Project
This could be because the task which is showing the error may not have launched in project; the task status is still set to “New”. To verify, have a look at the task status in project.
Go to project and task code,
Change the status by click on action icon (three dots) at the task line and click “Change status”
Change the status from “New” to “Launched”
Go back to scheduled invoice function and try to run it. It should be fine if there are no other errors.
Hope this helped to fix the issue in scheduled invoice generation function.
