@CWesener, thank you for your response.
->As per I have understood the concept of CDS, it is the common database for all the platforms.
If I require the additional entities or fields, I can create my custom ones if not present in CDS. I can make use of Microsoft Flows to sync the data among multiple platforms using CDS. Also, I can generate the power BI reports using CDS environment. MS keeps redundant data for customers (their common fields/attributes) in CDS, Dynamics 365 sales (CE), and Dynamics 365 Finance and Operations, if I talk about 365 sales and FinOps integration for an example.
Is this understanding correct?
->I am able to select the environment in the PowerApps portal. No issue with that.
Can I still get clarified with the below issues I got?
->How to see the data in CDS? I am not able to see the same data in the CDS trial instance like that in Sales instance.
->How to create the customer in Finance and operations, if an account is created in Dynamics Sales.
->I have created the trial instance for Finance and Operations. But I am not able to select the environment of the created instance during data integration as in the attached snapshot. How to get the trial instance for Finance and operations?
->Most of the templates provided make use of Finance and operations while creating the project.
What can be the way if I want to sync data between other platforms? For example - between outlook
web and D365 sales?
