when multiple MAs present in fimsync belonging to same domain, how to define attribute precedence.

Hi,

In our environment there are multiple MAs and i have to define proper precedence of attribute flows in order to function properly. The list of MAs present are

1. FlatFileMA

2. FIM MA

3. ADDs MA

4. Google Apps MA

We are provisioning the user from FlatFile to FIM, and then from FIM to AD, FIM to Google Apps MA. Some times the provision directly takes from FIM to AD and from FIM to Google Apps MA. In order to achieve this how should i assign the attribute precedence. The attributes that are using are accountName,firstName,LastName etc..

We are using Code Based provisioning...

Thanks
