The difference of F-28, F-32, F44 & F53
Apart from processing open items, what is the difference between:

1. Accounting-->FA-->AR-->Document entry-->Incoming payment > F-28 and
2. Accounting-->FA-->AR-->Account-->Clear F-32 and the difference between F-53 and F-44 in AP.

When you post a transaction, you will get a Accounting document.

If you are creating a payment document through F-53 or F-58 without linking the Accounting document,
then we have to create a link between the accounting document and payment document and that can be done through F-32 (for GL) and F-44 (for AP).

An good example is when we make down payment, a payment document is created.
If we post the invoice, an accounting document is created.
To clear this payment document and accounting document, F-44 is used.

- F-28 will be used to make trasactions for income payments.
Eg: If you receive from a customer by using above T code will be passed necessary entries.
- F-32 will used used for clear the Customer line items.
- F-53 will be used for making payments to vendors.
- F-44 will be used for clearing the Vendor Line items.
