1 简介

标准的 SAP 采购订单消息输出不会带税金额，但实际业务都会有税金额产生，这时候我们不得不选择做增强+创建自定义 Adboe form 的方式满足实际业务。

2 业务数据例子

PO 表头和行项目明细分别增加，自定义字段 PO 总金额（净价+税价）和自定义 PO 税金额和税码。自定义的 PO 总金额和 PO 税金额反映到 Adobe 自定义模板。

1）BADI: MM_PUR_S4_PO_MODIFY_HEADER

4 自定义 Adobe form

自定义 PO Master form 和 PO form 关联起来。基于标准的 PO Master form 和 PO form 复制下来，然后再增加税金额字段。总金额字段重新命名成自定义字段，这样才能接收到前台 PO 自定义总金额数据。

1）PO Master form

2）PO form

5 前台主数据配置

基于常规的消息输出挨个定义即可。

6 后台配置

1）基于常规规则定义输出，可以参考标准来配即可。

2）关联自定义的 PO Master form 和 PO form。
