As part of a Power Platform project, the objective is to implement a mobile purchase request management solution.
The application is based on a Power Apps Canvas app (with PCF), and two architectures are being considered.
In both cases, the application is primarily used to read data from Dynamics 365 Finance & Operations. The only planned write operation concerns the creation of an order in Dynamics 365.
The first scenario involves a Power Apps Canvas app that calls an Azure Function. The Azure Function then interacts with Dynamics 365 Finance & Operations (via API or MCP) as well as Dataverse, without a direct connection between Dataverse and D365.
The second scenario is based on a Power Apps Canvas app that writes to Dataverse, after which a Power Automate flow transfers the data to Dynamics 365 Finance & Operations, potentially with bi-directional synchronization.
In both architectures, what are the licensing implications for the Power Apps users?
