SAP Note 11067 - Error across posting period during manual payments.

Symptom

The following message can be output for manual clearing procedures
(for example, vendors outgoing payment F-53, incoming payment F-28):
Posting period not opened.
A company code (for example BUK2), which is different to that
entered with posting (for example, BUK1), is displayed in the
field Company code.

Cause and prerequisites

It is defined in table T041B that the company code (BUK1) also
makes manual payments for other company codes. A company code
(BUK2) without valid posting periods is available there.

Solution
If you really want to carry out intercompany clearing, you must
also provide the corresponding company codes with posting
periods, otherwise you should delete the irrelevant entries in
T041B using transaction OB60 or via the following menu path:
Financial Accounting configuration menu; Bus.transactions;
Accounts receivable; Incoming payment; Manual payments
