SAP RETAIL 參考PO建立配置設定表之一
在SAP零售系統裡，可以基于配置設定表來建立采購訂單，也可以參考一個采購訂單來建立配置設定表。繞不繞？SAP就是這麼靈活！
1，采購訂單号：4500000736. 它是使用ME21N建立的。它是一個普通的外購采購訂單，如下圖示：
ITEM DETAIL裡的RETAIL頁籤裡ATab-Rel.字段值被設定為1。 如上圖。
2，執行事務代碼WA01，
系統彈出如下視窗，輸入上面的采購訂單号，
執行，進入如下界面，
選中item，點選按鈕‘Adopt in alloc.tbl’, 進入如下界面，
注意：這裡的供應商欄位為空，且不允許輸入任何值。系統自動在Distribution Center字段處将工廠NM01的customer code 40填好了，且不允許修改。如上圖。
維護好其它資料，儲存，
系統報錯說：Item category (ZB) not allowed.
3，看該報錯資訊的F1 幫助文檔：
Item 00010: item category (ZB) not allowed.
Message no. MW339
Diagnosis
Item category ZB is not allowed for item 00010. The item has been created referencing another document. This means that the item categories possible are limited.
When an item is created referencing a shipping notification, an item category must be selected that only allows goods to be moved between distribution centers and stores (that is, generation of warehouse orders and deliveries as follow-on documents), and does not allow purchase orders to be generated for external vendors.
System Response
The system does not include reference document items in the allocation table if:
a promotion number is maintained in the reference document item
the reference document item contains a material that is a variant referencing a generic material (higher-level item)
Otherwise the reference document item is adopted in the allocation table. The item category can be changed in the allocation table.
Procedure
Select a valid item category.
4，根據F1幫助文檔的說明，SAP 零售系統中如果要參考采購訂單來建立配置設定表（Allocation Table），該采購訂單不能是向外部供應商采購的單據，而隻能是DC到門店或者門店到門店的補貨訂單。
