Solution: Data Entity synchronization errors in #Dyn365FO

After creating a data entity you might receive the following 15 errors upon building it, these recommend you to do a full build of your package but this will not resolve the issue. The cause of this error is an existing entity record in your DMFEntity table and like some solutions have mentioned that you delete those records and rebuild they will work for only once but when you make changes and run a build again you will get a the same errors, so lets come to what is causing this. It is clear that there is a duplicate but when I verified that there is none according to my Entity name and table names within the DMFEntity table that could cause a duplicate, what could it be? Well to your and my surprise the label you have on your entity is also a factor when it comes to duplication. And since D365 has existing data entities for a number tables out of the box it is quite possible that your new entity that you built got the default table label.

Solution:

Give your entity a custom label.
