Understand the Impact of Taking Actions on Objects Referenced by Reports

When you move, cut, rename, or delete a Data Model, a Sub Template, or a Style Template that's used as a resource for a report, the references to the resource are broken and the report can't run as expected.

For example, if you've a report that was created with a data model that resides in a folder called My Data Models, and you move the data model to another folder, the report can't run because the report definition is expecting to find the data model in the My Data Models folder.

If moving a resource object is unavoidable, then you must edit each report that references the object to refer to the object in its new location.
