Hi
If the accounting document exists check the LOGSYS value in the VBRK table. Sometimes when you carry out a client copy for example the LOGSYS value in table T000 VBRK and BKPF can be out of sync so the document is not found in Vf03 when the system reads the BKPF table.
When you call the accounting document TAB in VF03 it will call function module FI_DOCUMENT_FIND_FOR_INTERFACE. You can see in here the direct read on BKPF using the
logsys as part of the selection key. So if the logsys in vbrk and bkpf are not the same as T000
the FI document will not be found and displayed in VF03 despite the fact that it exists in BKPF.
This is discussed in an old note 28958.
Hope it helps
Kind regards
Brian
