Answer 1

Hi
The main parameters of BAPI BAPI_ACC_DOCUMENT_POST are:
- DOCUMENTHEADER (BAPIACHE09) to transfer the header data
- ACCOUNTGL (BAPIACGL09) to transfer the g/l item data
- ACCOUNTRECEIVABLE (BAPIACAR09) to transfer the  customer item data
- ACCOUNTPAYABLE (BAPIACAP09) to transfer the vendor item data
So u need to use one of parameters above to transfer the header and item data, the amount data for every item have to be transfered by parameters CURRENCYAMOUNT
U should also considere the posting key is automatically set by BAPI, and it depends on the item type and the sign of amount:
- 40/50 for G/l
- 01/11 for customer
- 21/31 for vendor

3 40 144000     Input-VAT            20090925                           V4                      34.74
4 31 1019186    B.E.N. MR SAUVAT                                        V1                     239.20-
Lines 1/2 data move to ACCOUNTGL and  CURRENCYAMOUNT
Line   4   data move  to ACCOUNTPAYABLE and CURRENCYAMOUNT
The line 3 seems to be a TAX line, in this case u need to use ACCOUNTTAX and CURRENCYAMOUNT
The header data to be transfered to DOCUMENTHEADER
