"The data model of your module is inconsistent with the database"

"The data model of your module is inconsistent with the database"

  
Hi
I'm trying to create a databse where I link sub accounts to a primary account. I want to create a one to many relationship effectively
So i have one entity "clients" and another entity "accounts". I have bootstrapped separate data sets to each entity but they share common attributes
When I drop the entity data into my  "accounts" preparation I see the error "The data model of your module is inconsistent with the database". Do you know what this warning is and why I'm seeing it?
Thanks
Rhys

Hi there! 

Have you been able to sort this out? I am not sure why you are getting this error, but if you could post the module I would be glad to take a look at it...

Cheers,
