Down payment config

Question

Hello Gurus,
I am trying to configure the down payment functionality which has been never been used. I have created new recon account and SPL GL account other than which assigned in vendor master recon. Then I have assigned recon accounts for SPL GL indicator A and F in T code OBYR or FBKP.
When I am using T code F-47 I am getting this error below. It says XXXXXX but i have assigned YYYYYY( IS it like both the vendor mater and the OBYR should have same recon account as it worked when i change it to XXXXXX. And after I created a down payment request in F-47 and I ran fbl1n to se if open items are there but couldnt find it there. Any help will be appreciated
""No special G/L acct defined for acct type K sp.G/L ind. A recon.acct XXXXXX
Message no. F5008
Diagnosis
You want to post via a special G/L indicator which was not maintained completely in the system. The specification on which reconciliation account is to be updated in the general ledger is missing.
System Response
The line item cannot be entered.
Procedure
In system configuration enter a special G/L account corresponding to reconciliation account XXXXXX for account type K and special G/L indicator A.""
