Extract data from Dynamics 365 and storing them in Azure Synapse

I am looking to move entity data from Dynamics 365 to Azure Synapse (formerly called Azure SQL Data warehouse) with a star schema (preferably), using Azure Data factory.

I have tried to get an end to end process established using wrangling data flow in Azure data factory. This appears to work, but there seem to be some data loss when saving it to the data warehouse.

Now, I am looking to try mapping data flow, to see if this will solve my issue of data loss.

I am quite new to the world of data engineering. so, happy to work with any proposed solution design.
