Do F-32 Clear Customer and Process Open Items just do BKPF/BSEG adds/chgs ?

Question

!uestion 1:
When a user executes F-32 in  "clear customer" and "process open items" modalities, are BKPF and BSEG the only tables that actually get changed via adds or updates?
Or are there other tables affected as well?
Question 2:
If BKPF and BSEG are the only affected tables, can I safely emulate the effect of the F-32 Clear Customer and Process Open Items Modalities by:
1) examining the BKPF/BSEG records added or changed;
2) using the appropriate BAPI(s) to accomplish these adds/changes (like BAPI_ACC_DOCUMENT_POST)
Question 3:
If BKPF and BSEG are NOT the only tables affected by F-32 Clear Customer and Process Open Items, can I emulate these modalities of F-32 thru an appropriate combinaton of BAPIs ?
Note:
The reason Im asking these questions the way I am is because a search  of SDN turns up no really good answer to the question of whether the Clear Customer and Process Open Items modlaities of F-32 can be emulated by one BAPI or a combination of BAPI's.
So by formulating questions (1-3) the way I have, I'm hoping that someone will provide SDN with a clear and definitive answer to the "F-32 BAPI Emulation" question.
Thanks for any expert advice anyone can provide.

Answer 1

Actually, the "right" answer in this case is to call CLEAR_DOCUMENTS and model the call after the call in PRELIMINARY_POSTING_ZANF_CLEAR
