Data collection tool

One possible solution for the author could be to use Microsoft Forms or Power Apps, which can be easily integrated with Power BI. Both of these tools allow users to create custom forms and surveys to collect data and can be used to send automated reminders to users.

Another solution could be to use Power BI's own data collection feature, Power BI dataflows. With dataflows, users can create ETL (Extract, Transform, Load) processes to collect and transform data from various sources, including Microsoft Dynamics, and load it into Power BI for analysis and reporting.

Finally, you can consider using a third-party data collection tool that integrates with Power BI, such as Zapier or Integromat. These tools allow users to create custom integrations between different apps and services, including Power BI, to automate data collection and reporting.
