Parking document thru FB01

Hi All,

I used bapi BAPI_ACC_DOCUMENT_POST for posting...

Now the requiremnt is to give an option for Parking as well...

so i searched SDN ....and i got a FM PRELIMINARY_POSTING_DOC_WRITE..for parking with code as well...

but i m confused with code ....

thy have done posting first and then did parking....using the Doc. no .posted....

is this the rit way?

Please suggest.....

Thanks

Rahul
