Concept between FI-CA, FI-AR, and FI-AP

Question

Dear FI-CA gurus
Please help me to understand the concept of relationship
between FI-CA, FI-AR, and FI-AP.
Our customer is in utility industry.
They have both of corporate customer and personal customer.
So, in this case, all customers and suppliers of corporate or personal customer should be managed by FI-CA only?
Or, should I use FI-CA for personal customer, and FI-AR for corporate
Customer, and FI-AP for suppliers?

Hi Yoshitada,
Firstly to clear your confusion, FI-CA documents are not posted to FI-GL.
In FI-CA, all relevant financial postings and transactions with customers are recorded in the sub-ledger. After which, all these detailed financial transactions are then transferred to the general ledger (FI-GL) in the financial accounting system. The relevant financial data are summarized in the general ledger through a reconciliation keys.
When you are performing a non-statistical transaction in FI-CA(say, posting a misc dr\cr), the system by defaults records the transaction in a reconciliation key.When the daily transaction processing is completed, all non-statistical financial transactions through reconciliation keys are transferred to FI-GL. Thus, this activity ensures that FI-CA transactions updates FI-GL.
Hence only the GL account balance gets updated.
The activities involved in creating and closing of reconciliation keys and the subsequent transfer from FI-CA to FI-GLnormally happens through the batch run in IS-U.
Some useful t.codes-
FPF1-Creation of reconciliation key
FPF2-Close of reconciliation key
FPG4-Mass closing of reconciliation keys
FPG1-Transfer of reconciliation keys to FI-GL.
Hope it solves your query
Thanks,
