Example: Account Management in Multiple Logical Systems
You can manage your accounts distributed among various logical systems, depending on the bank posting area, for example.
You could use, for example, two Account Management Systems (FS-AM)
as account-managing systems.
Alternatively, you could use one (or more) applications (external systems) that are comparable to Account Management (FS-AM)
.
Two AM systems as account-managing systems
Some of the accounts are in AM system KO5CLNT500, some other accounts are in AM system KO5CLNT510.
Prerequisites
In the Customizing for Account Management (FS-AM)
for all account-managing systems (in the example, in KO5CLNT500
and in KO5CLNT510
), you have created your own implementation by choosing 
Communication with Logical Systems
Account
Account Business Add-Ins (BAdIs)
BAdI: System Determination for Accounts
.
For more information, see the documentation in the Customizing activity.
Process
The BAdI implementation System Determination for Accounts
provides the logical system that contains the contract for each account contract.
The account proxy, therefore, does not determine the account-managing system settings in Customizing for Account Management (FS-AM)
under Define Account-Managing System
.
