SAP Note 13383 - Error message F5060 when clearing net documents

Symptom:

Invoices and credit memos are posted using net document types.
When clearing using FB05 (vendor outgoing payments) or using
the payment program (SAPF110), the following error message appears:

F5060: Posting is only possible with a zero balance; correct document

Example: 2% cash discount; 15% input tax
Net document
31 Vendor 1217.56
40 Expense 1037.58
40 Cash disc. 21.17
40 Input tax 158.81
Credit memo
21 Vendor 1216.56
50 Cash disc. 21.16
50 Input tax 158.68
50 Expense 1036.72

Cause and prerequisites

The debit items and credit items are handled together for
cash discount clearing items, which means that a small remaining
amount can be created which is ignored when correcting the tax due
to rounding. This causes the error message to be issued.

In the above example, the tax amount to be corrected is 0.01 * 15%

Solution
Clear both items separately against a clearing account.
As of Release 3.0A, a tax posting is also possible for very small amounts in the case of cash discount clearing postings so that the tax adjustment is now also possible for automatic clearing.
