17、 to applicatio n53 Applicati on Docume nt posted簡而言之，IDOC 是類似 XML 的一種 SAP 系統(tǒng)與其他系統(tǒng)的一種集成工具。假設(shè) I04 和 I02 是同一個集團下兩個不同子公司的 SAP 系統(tǒng),I04 需要將其采購 訂單信息及時發(fā)送給 I02。下面簡單介紹 IDOC 的設(shè)置步驟,為了避免混淆，我的命 名都比較特別。1, 設(shè)置 IDOC Type.(1 WE31,創(chuàng)建 segment 類似于創(chuàng)建 XML 的結(jié)點及結(jié)點屬性。這里先輸入YPOHEAD ,點擊創(chuàng)建，在接下來的屏幕中，錄入EBELN, BUKRS, BEDAT等字段及他們對應(yīng)的 d

18、ata element 接著創(chuàng)建 YPOITEM ,輸入 EBELN, EBELP, MATNR,MENGE, MEINS 等字段及他們對應(yīng)的 data element。保存后用 SE12 查看你將發(fā)現(xiàn)，系統(tǒng)自動添加了 YPOHEAD 和 YPOITEM 兩個 結(jié)構(gòu)每個字段都成了 CHAR 類型,長度就是 WE31 中的 EXPORT LENG。(2 WE30,創(chuàng)建 IDOC Type,定義結(jié)點間的相互邏輯關(guān)系.先輸入 YPOIDOC ,然后點擊創(chuàng)建，緊跟著點擊 create new 進入。在主界面中，先 點擊創(chuàng)建按鈕，將 YPOHEAD 添加，設(shè)置 Mandatory seg 打勾，min

19、= 1, max = 1,代表我們每個 IDOC僅包含一張采購訂 單。然后在 YPOHEAD 下添加 YPOITEM ,同樣的 Mandatory seg 打勾,min = 1, max = 99999.2, 創(chuàng)建 Message Type.(1 WE81,創(chuàng)建 Message Type.先切換到編輯狀態(tài)，然后點擊 New Entries 輸入 YPO 即可。(2 WE82,關(guān)聯(lián) Message Type 和 IDOC Type.實例Outbo undIdoc-3 創(chuàng)建到 102 的端口 .首先確保系統(tǒng)內(nèi)已經(jīng)有到 102 的 R/3 Connection(SM59 ,如果沒有則先創(chuàng)建一個 名為

20、102001。接著 WE21 創(chuàng)建 Port，類型 TRANSACTIONAL RFC,名為 I02PORT , RFC desti nation則填寫 102001。4, SALE ,創(chuàng)建 Logical System.SALE, Sending and Recei ving Systems, Logical Systems, defi ne logical system新 增一個 logicalsystem 名為 I02LS ,這將作為下一步的 Partner。Define logical systems 下方，有 Assig n Clie nt to logical system,這里可

21、針對本系統(tǒng)(I04 定義 logical system,作為發(fā)送 IDOC 時的發(fā)送方標(biāo)識，我對 Client 001 的定義是 I04LS.5, WE20,定義我們的 Partner profile.在 PARTNER TYPE 為 logical system 下，創(chuàng)建一個 patner no 為 I02LS 的 partner ,type 填寫 LS。下面的 Permitted age nt 填寫 US(User, Age nt 為你自己的用戶名或某 basis 人員 用戶名。然后，點擊 outbound 下方的加號，創(chuàng)建一個 outbound parameterMessage Type

22、 為YPO , receiverport 為 I02PORT , output mode 選擇 tran sfer idoc immed., Basic Type 填寫YPOIDOC ,保存即可。6,編程發(fā)送 IDOC設(shè)置了這么多，真累啊，總算可以寫程序了，是不是很開心呢？程序的思路就是，把每個 IDOC 結(jié)點按字符串形式逐個添加，而字符串的添加次序自然也體現(xiàn)了 IDOC 結(jié)點間的 邏輯關(guān)系。代碼如下，DATA: ls_pohead TYPE ypohead,ls_poitem TYPE ypoitem,ls_edidc TYPE edidc,lt_edidc TYPE TABLE OF ed

23、idc,lt_edidd TYPE TABLE OF edidd WITH HEADER LINE.CLEAR ls_edidc.*系統(tǒng)根據(jù)下面 4 行即可與 WE20 設(shè)置關(guān)聯(lián)起來ls_edidc-mestyp = YPO. Message Typels_edidc-idoctp = YPOIDOC. IDOC Typels_edidc-rcvprn = I02LS. Part ner Number of Recipie ntls_edidc-rcvprt = LS. Part ner Type of Receiver*添加 IDOC 結(jié)點CLEAR lt_edidd.lt_edidd-se

ENDIF. 7,查看 IDOC.WE05 可以查看我們剛剛發(fā)送的 IDOC , BD87 還可對 IDOC 進行一些處理。-實例-Inbound Idoc 這 里將繼續(xù)沿用上篇文章的例子， 講述 I02對接收到的采購訂單信息進行的相關(guān)處 理。 1， 創(chuàng)建 IDOCType 和 Message Type.與上篇 Outbound Idoc

29、 中的前兩個步驟完 全一樣。2,創(chuàng)建一個function : Y_IDOC_PO_PROCESS.當(dāng) IDOC 設(shè)置完畢之 后， SAP 可以自動調(diào)用 該 FuntionModule 處理 IDOC。所以這個函數(shù)的接口都是規(guī) 范的。下面步驟中將介紹的 tcode：BD51中可以查詢到很多 Inbound Function，比 如 IDOC_INPUT_BBP_IV，可參照 創(chuàng)建我們的接口。 接下來就可以寫入 我們的代 碼，根據(jù) IDOC 內(nèi)容，創(chuàng)建相應(yīng)的銷售訂單。為了簡化，這里我們僅僅將其存到數(shù) 據(jù)庫表里面，請先創(chuàng)建兩個表 丫丫 02_POHEAD 和丫丫02_POITEM， 字段參考 WE3

30、1 中 的 YPOHEAD 和 YPOITEM。 然后 寫入下面代碼：DATA:lv_subrc LIKE sy-subrc, ls_chead TYPE ypohead, ls_citem TYPE ypoitem, ls_poheadTYPE y02_pohead, lt_poitem TYPE TABLE OF y02_poitem WITH HEADER LINE.
