Collection Management (FSCM) in Utility companies (FICA).

Hi Gurus

We have a client that is a utility company. It has implemented FICA where they manage all receivables and customer payment. Only summary  lines are posted to General Ledger and nothing is posted to traditional AR sub-ledger.

Client wants to implement FSCM - Collection management. As per my understanding FSCM collection management is integrated to traditional AR sub-ledger and cannot work with FICA alone.

Is my understanding right. In case it is not possible, what is the other solution we have in utilities similar to collection management.

Thanks
