Park the document with special GL posting

Question

Dear Friends,
I want to park the document with special GL posting in Xn code F-43. But I
am getting the error message that:-
Special G/L transactions not defined for bills/exch.and down pmnts
Message no. FP030
Diagnosis
You have selected a posting key with a special G/L indicator of type 'Bill
of exchange', or 'Down payment'. Document parking is not defined for special
G/L transactions of the type 'Bill of exchange' or 'Down payment'.
System Response
Document parking cannot be carried out.
Procedure
Select a different posting key or special G/L indicator. If the posting is a
'One-time posting' to a rent contract, select a different transaction type
or post the document directly.
In FBKP, for this special GL in Properties, I have selected the option Down
Payment/Down Payment Request.
Any clue, how can we park the document with special GL without changing this
property of special GL as mentioned above.

Dear Abhishek,
I see your situation now clearly. See we also have this type of requirement. You have made a down payment of say 100 and vendor is adjusting 10% of this down payment in its one invoice. You can have this sets of entries:
1) Vendor Down Payment - TCode F-48 or (F-47 and F110)
     Vendor Account Dr Posting Key 29 Spl GL A - US$ 100
      Bank Cr Posting Key 50 - US$ 100
2) Post Vendor Invoice FB60 or FV60
    Expense Acct Dr Posting Key 40 - US$ 1000
    Vendor Acct Cr Posting Key 31 - US$ 1000
3) Clear Vendor Down Payment - TCode - F-54
    Vendor Account Dr Posting Key 39 Spl GL A  - US$ 10
    Vendor Account Cr Posting Key 26 - US$ 10
So finally in your vendor account you will have 990 US$ to pay against invoice and 90 US$ as balance down payment to adjust.
Hope this meets your requirement.
