（原創）BAPI 修改銷售訂單的方法 ‘BAPI_SALESORDER_CHANGE’

sap 標準程式中可以使用VA02來修改銷售訂單 change sales order，也可以在程式中呼叫BAPI來更改訂單(如物料編號material，訂購數量 order quantity等)，用到的函式是 BAPI_SALESORDER_CHANGE.
sap bapi Explorer中的文件。

Method

SalesOrder.ChangeFromData

Change Sales Order

Functionality

You can use this method to change or delete sales orders.

You can change header, item, schedule line and configuration data.

In general, note that you should:

Only specify fields that should be changed

Select these fields by entering an X in the checkboxes

Enter a U in the UPDATEFLAG field

Always specify key fields when changing the data, including in the checkboxes

The configuration is an exception here. If this needs to be changed, you need to complete it again fully.

Maintain quantities and dates in the schedule line data

修改訂單數量要用schedule_lines 這個引數

Possible UPDATEFLAGS:

U = change flg值的三種不同意義

D = delete

I = add

Example

Delete the whole order
Delete order items
Change the order
Change the configuration

Notes

Minimum entry:

You must enter the order number in the SALESDOCUMENT structure.
You must always enter key fields for changes.
You must always specify the update indicator in the ORDER_HEADER_INX.

Commit control:

The BAPI does not run a database Commit, which means that the application must trigger the Commit so that the changes are read to the database. To do this, use the BAPI_TRANSACTION_COMMIT BAPI.使用完了bapi記得要用commit提交
