In Microsoft Dynamics 365, reports are solution aware. Adding a report as a component to a solution makes it become a single unit of software that extends Microsoft Dynamics 365 functionality and the user interface. Only reports that are organization owned or visible to the organization can be added to solutions.
To find if a report is viewable to the organization: In the list of reports, select a report, and then click or tap Edit. On the Administration tab, see if Viewable By is set to Organization.
You can add, import, or export snapshots of reports as part of a solution. In Microsoft Dynamics 365, reports, sub reports, report category, report display area, and report-related record type are considered as components of a report set. When you import a solution update in non-overwrite mode, any updates by the solution to a report will be ignored if any component of the report set has been customized.
