combine multiple task list

[Jeyganesh]

In our Sharepoint site We are using multiple subsites called development, helpdesk, sales all site has a seprate Task list.

Is there any way to view all site tasks as one view?

@Jeyganesh There is no easy way of merging tasks from multiple task lists into one view.

You can (if You have the Modern Experience) create a page and, on the Site Collection root site, insert the web part "Highlighted content" and configure it to only show Tasks. Perhaps not the best visual experience but at least you will get a list of all of your tasks. 

If You are using the Classic Experience You can place a Search Result Web part on a page and configure the query so that it only displays tasks from the current site collection.

Otherwise i would consider using "Planner" instead of SharePoint task lists. That givs You a much better overview and experience.

@MagnusGoksoyrOLDProfile : Thanks for the amazing solution. Is there a way we can further filter it by Assigned To and have a person's tasks displayed for him?
