Error publishing data entity to Azure SQL Server DB

Hi,

I have recently deployed a Dynamics 365 for Operations (July Update 7)
Installed platform version : Update7 (7.0.4542.35151)

I am attempting to publish to a Custom/Standard Entity (Bring Your Own Database)

I am getting an error like below.

Entity Customer groups cannot be published.
Error occurred during publishing the entity

Is there anyway on how to resolve the issue?
