【MM】基於收貨的發票校驗Bapi Demo

正常我們都會在供應商主檔和資訊記錄主檔中勾選“基於收貨的發票校驗”選項，意味著做採購發票校驗的時候需要基於收貨憑證。

      LS_ITEM-REF_DOC = LT_ZMSEG-MBLNR. 
      LS_ITEM-REF_DOC_YEAR = LT_ZMSEG-MJAHR.
      LS_ITEM-REF_DOC_IT = LT_ZMSEG-ZEILE.

下面分享一個簡單的Demo：

1、資料準備

  DATA: LS_HEADER TYPE BAPI_INCINV_CREATE_HEADER.
  DATA: LT_ITEMS TYPE TABLE OF BAPI_INCINV_CREATE_ITEM.

  PERFORM FILL_VALUES TABLES LT_ITEMS
                       USING LS_HEADER.

  PERFORM RUN_TO_CREATE_IV TABLES LT_ITEMS
                            USING LS_HEADER.
