1、BAPI_MATERIAL_SAVEDATA 修改物料信息

"物料描述
CLEAR:materialdescription,materialdescription[].

materialdescription-matl_desc = ls_in-maktx.
APPEND materialdescription.
CALL FUNCTION 'BAPI_MATERIAL_SAVEDATA'
EXPORTING
headdata = headdata
clientdata = clientdata
clientdatax = clientdatax
IMPORTING
return = return
TABLES
materialdescription = materialdescription[].这样写满足创建物料的基本视图和其中的字段，但是有一个问题，虽然写了毛重，但是实际传入的毛重没有生效。
2、毛重的字段增强
概述：对结构BAPI_TE_MARA和BAPI_TE_MARAX进行字段增强。
参考：ABAP增强开发：更新物料主数据毛重，净重，单位的BAPI使用方法(经典)_bapi_material_savedata增强字段写入-CSDN博客SAP-BAPI物料主数据修改毛重净重_料号毛重参数设置-CSDN博客
操作步骤：
（1）SE11 输入 BAPI_TE_MARA
（2）点击附加结构
（3）填写附加结构名称：一般以Z打头，加原结构名称，例如：ZBAPI_TE_MARA
（4）填写描述，可以和原结构描述相同，也可以自由填写。
填写组件，选择内置类型，CHAR，20，描述写毛重。
注意：数据类型比如是CHAR,如果使用，MARA-BRGEW，这个类型是QUAN，在后面BAPI扩展赋值时，会报错。
扩展类型里面都是CHAR,为了确保传输数据类型一致，定义组件的数据类型必须是CHAR.
(5)保存、激活后，返回BAPI_TE_MARA，展示如下图
（6）同理，对BAPI_TE_MARAX进行扩展组件，扩展后如下：
这里注意一下ZBAPI_TE_MARAX中的BRGEW的组件类型为 BAPIUPDATE
3、程序修改，加入扩展字段
DATA: BEGIN OF w_extensionin OCCURS 0.
INCLUDE STRUCTURE bapiparex. "BAPI 参数 ExtensionIn/ExtensionOut 的参考结构
DATA: END OF w_extensionin.
DATA: BEGIN OF w_extensioninx OCCURS 0.
INCLUDE STRUCTURE bapiparexx. "Extension In/Extension Out 的复选框结构
DATA: END OF w_extensioninx.
DATA: zbapi_te_mara LIKE bapi_te_mara. "客户定义字段:客户级别的物料数据
DATA: zbapi_te_marax LIKE bapi_te_marax. "客户定义字段:客户级别的物料数据

4、总结
在直接使用BAPI_MATERIAL_SAVEDATA 创建、修改物料信息时，毛重字段不生效。此时需要进行增强开发，先对字段进行扩展，再在程序中增加扩展字段的赋值。
