endform. " FRM_INVOICE_CREATE2注意：
在PO收货后，做发票校验，发现一个问题，就是在headerdata中有个参数 calc_tax_ind ，如果将这个值‘X’，那么在
ME23N中会看不到生成的发票校验凭证invoicedocnumber的值。
headerdata中的必输值：
invoice_ind 为'X'
doc_date
pstng_date
comp_code
currency
gross_amount
itemdata中的必输值：
invoice_doc_item
po_number
po_item
item_amount
quantity
po_unit
ref_doc
ref_doc_year
ref_doc_it
