How to consider AR Balance transfers while reporting Open AR

Question

I am using infosource 0FI_AR_6 and 0FI_AR_4 to get AR information into BW.
While doing year end close in ECC, open AR balance was transferred from 2006 to 2007.
When I execute transaction FAGLB03 in ECC, it shows me the Open AR balance.
Is this Balance transfer available in any key figure in BW?
When I report in BW, how do I get the current open AR balance which includes the open AR from last year. I prefer not looking at each transaction in previous years in the system to determine Open AR as the performance will keep getting worse as time passes.
Please let me know what is the best solution for getting open AR balance in such cases.
Thanks

Answer 1

1. AR down payment invoice is closed when you raising incoming payment. So this AR down payment invoice will not appear in incoming payment selection list
>>> Yes
2. Further due to partial payment, only AR invoice will be in open status and this AR invoice will appear in incoming payment selection
>>>the problem is that the AR invoice is registered with a less amount than the amount of the incoming payment
3. If you want use Payment on account for balance amount, are you able to choose customer account at GL account field?
>>>the AR invoice is just closed with incoming payment
4. I don't think it is possible to post balance amount via payment on account. To get correct BP account balance, we have to post at customer account.
>>>Yes. But if you open the report Sales --> Sales Report --> Open Report --> Incoming payment you continue to see the open amount of the Incoming payment.
After all my idea is to register a not real AR invoice (really not exist) to link to the open amount of the Incoming payment:
01: In the report Sales --> Sales Report --> Open Report --> Incoming payment I will not have more open amount
02: After that I will adjust BP account balance with a post at customer account
Thank you for your opinion ....
