abap-MRP自動產生採購申請-BADI增強-將銷售單和行號複製為需求追蹤號

這是很早以前做的一個開發，這裡記錄一下，做個備忘。
業務背景:1000公司的銷售訂單經過 MRP  運算後訂單的每行都會轉換成一個對應的採購申請單(對2000公司)，生產計劃人員需要按銷售單彙集採購申請製作一張對2000公司的採購訂單。問題就出在這裡，當用 me21n建採購單，尋找採購申請時，沒有相應的按銷售訂單查詢的條件，如:

如果要增強 me21n 程式，理論上可以但難度較大。於是從另一個角度來解決這個問題，見： 每個採購申請行都會有一個 "需求跟蹤號" , 如果在採購申請建立時，能夠把相應的訂單及行號填到 需求跟蹤號 這個欄位裡，那就能解決這個問題了。延著這個思路，我們去找 mrp 運算相關的增強，進後台配置，如:

找到一個可用的 badi ，按照它的說明(後面附了說明),建立這個 badi 的執行個體, 可以用 se19 直接進入，如:

實現 Before_save 的方法:

測試結果very good:

這樣就可以用 需求跟蹤號 來尋找了.

SIMGMD_PURREQ_CHANGE

Use

Application components:  PP-MRP-PP, MM-PUR

Function groups: M61P, M61U

You can use the Business Add-In (BAdI) MD_PURREQ_CHANGE to change data, before posting, for purchase requisitions, which have been created, changed, or deleted as a result of the materials planning of a material, or which have been created as a result of conversion of a planned order.

You can use the Business Add-In to fill and change fields from purchase requisitions in tables EBAN and EBKN: Customer include CI_EBANDB also supports filling customer-specific fields when changing fields in the table structure EBAN.

You can execute the Business Add-In in the planning run in the following areas:

• Material requirements planning

• Master production scheduling

Standard settings

• The Business Add-In is not active in the standard system

• The Business Add-In cannot be used multiple times

Activities

 

To activate the Business Add-In, you must create an active implementation. To do this, choose the following path in the SAP Menu: Tools -> ABAP Workbench -> Utilities -> Business Add-Ins -> Implementation

 

For more information about this procedure, see the SAP Library under

• Basis Components -> ABAP Workbench -> Changing the SAP Standard -> Business Add-Ins -> Implementing Business Add-Ins.

 

Example

In the sample coding provided, the fields business area, controlling area and profit center are filled for purchase requisitions with account assignment to a sales order. The system reads the relevant data from the sales order and transfers it to the purchase requisition.

This sample implementation thus replaces the modification proposals from SAP Notes 303243 and 357713.
