Templates or template files are .atpt files that carry the design and layout of views (reports, dashboards, and tables) in your workspace. Template files can be used to copy views from one workspace to the other. This reduces the effort and time involved in creating similar reports across different teams, departments, or business units.
Note:
Template files do not include the underlying data and only carry the design blueprint of the views.
All views in a workspace can be exported as a template. This includes:
Yes, you copy views from one Workspace to another.
Yes, you can copy views from one account to another?
Yes. If all related/dependent tables are imported into the destination workspace, the lookup relationship between them will be retained.
In case any related tables are not present in the template file, you can choose to remap the views to the tables in the destination workspace manually.
