Ff759 during creating billing document

Question

hi guys
During  sales order process with Customer Down Payment (for Poland) I'm getting an ff759 error when I'm creating  billing document .
Message no. FF759.
Cannot post document: tax base in local currency is zero.
You tried generating a document in which the tax base in local currency is zero although the tax amount and tax base in foreign currency is not zero
System is not creating an accounting document.
The billing document that I'm creating in that case  is a regular invoice (type F2) that uses a downpayment invoice (type FAF) for clearing.
Both invoices are in local currency.
I'm sure the error is  because of some tax rounding isuess.
We have implented every note relating to Down Payment  for Poland and to FF759 error.
My system SAP ECC 6.03 , SP04
Any ideas??
thx
Raf

Alex, thank you for your answer, but it didnu2019t solve my problem, most of the notes that you wrote about are relating to invoice correction,
and like I wrote before our problem is happening only during  sales order process with Customer Down Payment (Down payment process for Poland is different than in other countries) when weu2019re creating  billing document.
Error  is being trown from  infunction FI_TAX_SV_TAXITEM.
Prüfung: Steuer <> 0 und Steuerbasisbetrag = 0
    IF ( i_bset-hwbas = 0 AND i_bset-hwste != 0 ) OR
       ( i_bset-fwbas = 0 AND i_bset-fwste != 0 ) OR
       ( i_bset-h2bas = 0 AND i_bset-h2ste != 0 ) OR
       ( i_bset-h3bas = 0 AND i_bset-h3ste != 0 ).
no error in case of external system is active             "N515047
AND  billing document AND bas-amount = 0                  "N515047
prerequisite: note 549712                                 "N515047
      IF  ext_activ IS INITIAL                              "N515047
     OR  i_bkpf-awtyp NE 'VBRK'.               "N515047   "N1174393
       or ( i_bkpf-awtyp NE 'VBRK' and                      "N1174393
            i_bkpf-awtyp NE 'WBRK' ).                       "N1174393
        message_store 'FF' 'E' '759' blank blank blank blank.
      ENDIF.                                                "N515047
    ENDIF.
btw. != means different
Beside that I would like to let you know that thanks to substitution described in note 872449 point 5c I was able to avoid ff759 error when I was creating billing document, but unfortunately in that case  posting document was incorrect.
