在执行BAPI_INCOMINGINVOICE_CREATE 之后，正常生成了发票号，但是系统会dump

数据会回滚

dump如下

查阅后得知相关note:1894901

原因是在填写税行的时候，输入了多行，将数据合并为一行后即可

代码如下：

  ls_headerdata-invoice_ind  = 'X'.
  ls_headerdata-doc_type     = 'RE'.
  ls_headerdata-doc_date     = sy-datum.
  ls_headerdata-pstng_date   = sy-datum.
  ls_headerdata-bline_date   = sy-datum.
  ls_headerdata-comp_code    = 'CV01'.
  ls_headerdata-currency     = 'CNY'.
  ls_headerdata-del_costs_taxc     = 'J2'.


  SELECT  * INTO TABLE lt_ekpo
  FROM ekpo
  WHERE ebeln = cs_head-ebeln_cv01.
  IF sy-subrc = 0.
    LOOP AT lt_ekpo INTO ls_ekpo.
      CLEAR:lv_tax_amount.

      lv_item = lv_item + 10.   "发票行项目号

      PERFORM frm_get_tax_by_net_amount USING 'CV01' 'J2' 'CNY' ls_ekpo-netwr
                                        CHANGING lv_tax_amount.


      ls_headerdata-gross_amount = ls_headerdata-gross_amount + ls_ekpo-netwr + lv_tax_amount.

      lw_itemdata-invoice_doc_item = lv_item.
      lw_itemdata-po_number        = ls_ekpo-ebeln.
      lw_itemdata-po_item          = ls_ekpo-ebelp.
      lw_itemdata-po_unit          = ls_ekpo-meins.
      lw_itemdata-quantity         = ls_ekpo-menge.
      lw_itemdata-item_amount      = ls_ekpo-netwr.

      lw_itemdata-ref_doc          = cs_head-mblnr_cv01.
      lw_itemdata-ref_doc_year     = cs_head-mjahr_cv01.
      lw_itemdata-ref_doc_it       = ls_ekpo-ebelp+0(4).


      APPEND lw_itemdata TO lt_itemdata[].


* fill tax data
      lw_taxdata-tax_code          = 'J2'.
      lw_taxdata-tax_amount        = lw_taxdata-tax_amount + lv_tax_amount.
      lw_taxdata-tax_base_amount   = lw_taxdata-tax_base_amount + ls_ekpo-netwr.

    ENDLOOP.

    APPEND lw_taxdata TO lt_taxdata.
  ENDIF.
