As mentioned in the previous recipe, a great benefit of creating a master library is to save you time and reduce the complexity by applying global changes to your visualizations.
There are three main areas in the asset panel when editing a Qlik Sense sheet (Objects, Fields, and Master items). Clicking the chain button opens the Master items pane.
From here, you can manage every aspect of the Master items, such as renaming, replacing, deleting, and editing.
You can continue to use the application from the previous recipe.

in the search box of the asset panel on the left of your screen. While there are no charts called Geo, the search has flagged up our two tagged dimensions in the master library pane with a yellow circle like this .If you delete a Master dimension or Master measure, the visualizations that use the deleted Master item will not work unless you replace it with a new dimension or measure. The same applies to deleting a field from the data model; the reference will remain a part of the Master item pane until it's updated from the edit screen.
Echoing a comment in the previous chapter regarding time saving and creating Master measures, replaces the need to write expressions as variables for reuse. Another piece of QlikView functionality that has been replicated and expanded upon is the concept of linked objects. Any updates you make in the Master visualization area will be applied globally.
If you rename a field in your script without moving the position it will be applied automatically to all the objects.
