Hi Linda,
Here is my opinion about you questions:
1) If you don't manage Check in system, it's enough for your AP flow.
But, if you manage Check in SAP system, the transactions from F110 will be:
Dr Vendor account
Cr Check
Eventhough Vendor item is cleared, but the Check is still open item.
And when your supplier clear Check, you have to enter it in system and the Check item is cleared.
This is the end of AP flow if you manage Check in system.
2) Transaction code F-44 is used to clear Vendor manually by listing all open item of Vendor with debit and credit amount, even Special GL. It differs from posting with a clearing transaction or posting with a payment in the following ways:
- You do not need to enter a document header
- You can only clear open items from one account.
It means you absolutely can see the open item in F-44 after posting invoice through FB60/
The scenario of F-44: There are some postings on Vendor account (e.g. Invoice, credit memo and transfer posting...) that are not cleared. You want to clear the postings.
3) In your case, it's not correct.
You said that you used FBRA to reset cleared doc 456. It cannot generateds new doc 789.
If you reset and reverse through FBRA, one new doc is created.
Please check again your case.
