Hi @vidyarani, it should work with windos scheduler and setting a trigger OnPostReload, /l will keep the document open, /r can be used to save and close the document, leaving it closed to allow next execution to open it again.
Confirm that the credential executing the task has access to \\YZWK01\QlikView\Dashboard\NewFolder. Or set the user you are executing the manual load as the credewntials to execute the task.
Also, in module security (CTRL+M) you need to give access to system (I suppose you already has because it's working manually).
Other issue can be caused becasuse the credentials launching the task doesn't has a Qv license.
If you manually launch the windows task, what does it do?
