One of the high-risk areas when moving systems is the expectation that all reports used in the past will be the same as the reports needed in the future. Modern business applications are designed to minimize the number of paper reports that an organization needs to produce, and the focus has moved to use of on-demand inquiries, exception reporting, and data visualizations using tools such as Power BI.
Both Microsoft D365 Business Central and Finance and Supply Chain Management (F&SCM, formerly Finance and Operations) have dedicated role-based workspaces, where information critical to a user’s job performance is splashed over the home screen. Configured list views (for example, all AR accounts over $1000 over 30 days) can be created easily and distributed as widely as necessary without the need to develop and run special reports.
There is a real risk that that effort, time and money is committed to writing reports that are no longer needed. When preparing a report inventory, consider grouping the reports currently used under the user role (who uses the report, not who generates the report). Describe what the report is used for, as well as the frequency that it is run. This way, as part of the implementation project, the team can ensure people can get the information they need to perform their jobs whether or not that information is in a report format.
