BAPI_ACC_DOCUMENT_POST and tax posting through the BAPI

Question

Hi,
We are using the BAPI_ACC_DOCUMENT_POST to post accounting documents. The BAPI works fine without the tax data but we need the tax data also to get posted for the line items. Please let me know how the ACCOUNTTAX
and CURRENCYAMOUNT table parameters needs to be populated.
A sample code would be of much use.
Currently if we have 3 line items in GL to be posted we fill 3 line items in AccountGL table, one line item in Accounts payable table, 4 line items in the currency table ( 3 for the actual items and 4 th item with summed up quantity of all 3 items) .
Your help is greatly appreciated.
Regards,

> DOCUMENTHEADER

if you set a different year or period from the value that you have in the posting date the bapi trigger an error

>       TAX_CODE       = tax code
if you set a different doc_type or company code for each item the bapi trigger an error

usually for calculate the correct value i use these functions 'CALCULATE_TAX_FROM_GROSSAMOUNT' or 'CALCULATE_TAX_FROM_NET_AMOUNT' it depends if i have the net or gross amount.
for example:
DOCUMENTHEADER                                  
>        BUS_ACT                    =    'RFBU'
>        USERNAME                =    sy-uname
>        HEADER_TXT              =    'my_text'
>        COMP_CODE              =    '0001'
>        DOC_DATE                  =    '20080115'
>        PSTNG_DATE              =    '20080115'
>        FISC_YEAR(1)              =    '2008'
>        FIS_PERIOD(1)             =    '01'
>        DOC_TYPE                  =    'SA'
