F110 Payment to vendor with several bank accounts

Question

Hi to all,
I have a vendor with 2 bank accounts, each one for its subisidiaries .
We pay this vendor's head office via transfer and to do so, use transaction F110. Depending on the subsidiary, our vendor wants us to use one account or the other.
All open items go under the head office number, my question is: how do I assign the right bank account to the open items?
I tried with the alternative payer funcionality but did not work.
Can you please help?
Cheers

The BVTYP is free. If a bank account accepts only one currency, the easiest is to take this currency as BVTYP in LFBK. You should have your own rules for the others cases: for example BVTYP 'EUR' for euro and 'OTHE' for all others currencies. You should use substitution with user exit. If you don't know the technique, please search in forums with keyword 'RGGBS000'.
The user exit should do the following (for example):
1) search in LFBK one row with LIFNR = BSEG-LIFNR and BVTYP = BKPF-WAERS.
   if found then BSEG-BVTYP = BKPF-WAERS
2) if not found, search in LFBK one row with LIFNR = BSEG-LIFNR and BVTYP = 'OTHE'.
   if found then BSEG-BVTYP = 'OTHE'.
3) if not found, do nothing; BSEG-BVTYP remains empty.
- With such an exit, you have to fill BVTYP in LFBK only when the suppllier has more than 1 bank account.
- You should also decide whether BVTYP should be ready for input or not; if yes you should decide what has priority: user's input or substitution (but I think that leaving the field ready for input and overwrite it in substitution has no sense and is dangerous, so in this case the substitution should do nothing for non empty BSEG-BVTYP).
