PowerApps Dataflow: is your CDS entity primary field name exactly the same as an entity name? Well, don’t.

The Issue:

Unable to load data to the existing custom entity on CDS from CSV or Excel via Dataflow.

We renamed the primary Name field for our custom entity and this is how it’s all started.

Error:

Load to Common Data
Service failed. Details: Bad Request

Testing 1 . Trying to load data to a new entity … It doesn’t like that entity name is the same as a primary field name, apparently.

Testing 2. Let’s change the entity name

Test 2. Rename a primary field. Trying to load data to the existing entity …

The conclusion

After the 2 weeks long conversation with the support team this is your available solution: don’t name your primary field the same way you named your CDS custom entity. You will not be able to use import via Dataflow!
