MB21 创建预留

一、MB21

输入物料等信息，保存即可

 二、调用BAPI：BAPI_RESERVATION_CREATE1

三、增强字段

里面涉及到特殊库存标识SOBKZ，在RESB表中存在，但是在BAPI中没有，需要用增强导入

创建结构：

BADI：MB_RES_BAPI_CREATE1

  
"-----------------------------------------@斌将军--------------------------------------------
METHOD if_ex_mb_res_bapi_create1~extensionin_to_resb.
      DATA:ls_extension LIKE LINE OF it_extension_in.
      DATA:ls_resb LIKE LINE OF resb.
      DATA:ls_resb_append TYPE zwms_resb_append.

      LOOP AT it_extension_in INTO ls_extension.
        IF ls_extension-structure = 'ZWMS_RESB_APPEND'.
          ls_resb_append = ls_extension-valuepart1.
          READ TABLE resb ASSIGNING FIELD-SYMBOL() INDEX ls_resb_append-rspos.
          IF sy-subrc EQ 0.
            -sobkz = ls_resb_append-sobkz."特殊标识
          ENDIF.
        ENDIF.
      ENDLOOP.
  ENDMETHOD.

调用BAPI时，传入特殊标识，RSPOS传入个行号就行
