使用BAPI_MATERIAL_SAVEDATA无法写入扩展字段

1.目的： 导入MARC增强字段 ZZJYFS， ZZBLBM， ZZBLTXT

 

 2. BAPI结构已经加上了增强字段

 

 3. 程序代码

    IF bapi_te_marc IS NOT INITIAL.
      bapi_te_marc-plant  = plantdata-plant.
      bapi_te_marcx-plant = plantdata-plant.
      CLEAR: extensionin, lv_marc_value.
      lv_marc_value  = bapi_te_marc.
      extensionin-structure  = 'BAPI_TE_MARC'.
      extensionin-valuepart1 = lv_marc_value(240).
      extensionin-valuepart2 = lv_marc_value+240(240).
      extensionin-valuepart3 = lv_marc_value+480(240).
      extensionin-valuepart4 = lv_marc_value+720(240).
      APPEND extensionin.

      CLEAR: extensioninx, lv_marc_valuex.
      lv_marc_valuex = bapi_te_marcx.
      extensioninx-structure  = 'BAPI_TE_MARCX'.
      extensioninx-valuepart1 = lv_marc_valuex(240).
      extensioninx-valuepart2 = lv_marc_valuex+240(240).
      extensioninx-valuepart3 = lv_marc_valuex+480(240).
      extensioninx-valuepart4 = lv_marc_valuex+720(240).
      APPEND extensioninx.
    ENDIF.

导入数据：

 值已经写到扩展结构：

 

 

BAPI执行结果，不会去更新扩展字段值
