BAPI_ACC_INVOICE_RECEIPT_POST balance error

Question

Hi.
I've read all the posts I can find about this BAPI. I want to post an invoice, but seem to be a problem somewhere.. Is there anyone who had such a problem or can help me please? Thanks.
The header is like this:
  gd_documentheader-obj_type   = 'BKPFF'.
  gd_documentheader-obj_key    = ref_key.
  gd_documentheader-username   = sy-uname.
  gd_documentheader-header_txt = 'HD BAPI Test'.
  gd_documentheader-comp_code  = '4020'.
  gd_documentheader-doc_date   = sy-datum.
  gd_documentheader-pstng_date = sy-datum.
  gd_documentheader-ref_doc_no = 'ttt'.
where i generate a random key for ref_key.
The account payable is like with corresponding currency amount:
  it_accountpayable-itemno_acc     = 1.
  it_accountpayable-vendor_no      = '2000001010'.
  it_accountpayable-item_text      = 'Test'.
  APPEND it_accountpayable.
  it_currencyamount-itemno_acc   = 1.
  it_currencyamount-curr_type    = '00'.
  it_currencyamount-currency     = 'EUR'.
  it_currencyamount-amt_doccur   = -100.
  APPEND it_currencyamount.
The account is:
  it_accountgl-itemno_acc     = 2.
  it_accountgl-gl_account     = '0064414401'.
  it_accountgl-doc_type       = 'KR'.
  it_accountgl-tax_code       = 'GQ'.
  it_accountgl-item_text      = 'Test'.
  it_accountgl-orderid        = '405200BE0800'.
  it_accountgl-fisc_year      = '2005'.
  it_accountgl-fis_period     = '07'.
  APPEND it_accountgl.
  it_currencyamount-itemno_acc   = 2.
  it_currencyamount-curr_type    = '00'.
  it_currencyamount-currency     = 'EUR'.
  it_currencyamount-amt_doccur   = 100.
  APPEND it_currencyamount.
And the tax:
  it_accounttax-itemno_acc = 3.
  it_accounttax-gl_account = '0062212201'.
  it_accounttax-tax_code   = 'GQ'.
  it_accounttax-acct_key   = 'VST'.
  it_currencyamount-itemno_acc   = 3.
  it_currencyamount-curr_type    = '00'.
  it_currencyamount-currency     = 'EUR'.
  it_currencyamount-amt_doccur   = 100.
The bapi will keep giving me the "Balance in current transaction" error, unless I remove the doc type KR in the header.
Many thanks in advance.
Tiago.

But I've got the same message when using the "AMT_BASE" instead of "AMT_DOCCUR".
I can post, but in a strange way..
If i do this, then i have 2 documents posted. A KR and an AB. But then, when i try to pass the BSCHL with the extends section in the BAPI i get wrong bschl error in the bapi...
