Best Practises for MOAC Configuration

Hi,

We have 17 Operating units defined in our Oracle environment.

The Profile Options value  like AR : Default Exchange rate type is different for some of the Responsibilities.

IF we set up a single Responsibility for AR which allow access to all the OU's, how will Receivables derive the value for this Profile as these  default to the transaction, receipts work bench?

After upgrade, we are planning to set up a single responsibility for AR, deactiviating the existing responsibility, defined a Global Security profile alowing accessing to all the OU's.

Assin the MO : Security profile value as Global Security profile defined above at the Responsibility level,
