Tasks

Tasks are used to perform a wide variety of operations and can be chained together in just any pattern. The tasks are handled by the Qlik Sense Scheduler Service (QSS). There are four types of tasks:

Reload
User synchronization
External program
Distribution

The Tasks overview lists all the available tasks. The following table presents the available fields and buttons. By default, only some of the fields are displayed. You can use the column selector ( Table ) to add fields.

You can adjust the column width by dragging the header border.

Task properties
Field/Button	Description
Name	The name of the task. Click to display the task chaining summary (only applicable for reload tasks with a task chain trigger applied).
Associated resource	The name of the app or the user directory connector that the task is used on.
Type	Type of task: Reload (for app) User synchronization (for user directory connector) External program (triggers a third-party program) Distribution task (triggers app distribution to Qlik Cloud)
Enabled	Status values: Yes or No.
Status	The status of the task: Never started: Task has never been started. Triggered: A request has been sent to the scheduler to run the task. Started: Task has started. Queued: Task is queued and will be started when preceding tasks have been processed. Queuing is controlled by the value of Max concurrent reloads, see Editing schedulers. Abort initiated: Manager scheduler has received the abort request but has not started processing it. Aborting: Manager scheduler has started processing the abort request. Aborted: Task has been aborted. Success: Task execution was successful. Failed: Task has been sent to worker scheduler for execution but failed to complete. For example, a reload can fail because of missing Read rights to the data connections or an error in the reload script. Skipped: Start of the task has been requested, but the task execution has for some reason not started. For example, the task might not be enabled. Retrying: Start of the task failed and a new attempt has started. Error: Task has not been successfully sent to worker scheduler for execution and returned an error. For example, an error can occur when there is no available worker scheduler to execute the task, or the application is already being updated by another task. Reset: State that the manager scheduler sets to tasks during startup, if their current status is non-terminal, that is, if they have states like Triggered, Started, or Queued, where execution has not yet ended. Click to open a summary of the latest reload or user synchronization tasks. Task status information
Last execution	The date and time of the last execution of the task. If never executed, no information is displayed.
Next execution	The trigger type that starts the next execution of the task: On task event trigger: The task execution is initiated by the completion of another task. On multiple triggers: The task has more than one trigger applied. The date and time for the next execution of the task is displayed if the task has a scheduled trigger applied. If the field is empty, no trigger is created for the task.
Tags	The tags that are connected to the task.
ID	The ID of the task.
Created	The date and time when the task was created.
Last modified	The date and time when the task was last modified.
Modified by	By whom the task was modified.
	Sort the list ascending or descending. Some columns do not support sorting.
	Type a string to filter on, or, when available, select a predefined value. All rows that match your filter criteria are displayed. You can filter on multiple columns simultaneously to narrow your search. If a filter is applied to a column, is displayed. To remove your criteria, click Actions in the table header bar and select Clear filters and search. You can combine filtering with searching. Searching and filtering in the QMC

Any rows that have been filtered out before selecting all rows are disregarded, even if they were selected. The option Deselect all rows is applied to all rows, including those that were filtered out.
