創建預留mb21添加附加字段的增強（在屏幕沒有需要的字段但是表RKPF和RSEB有）：

我們的需求是在表RESB里面有個特殊庫存字段SOBKZ，可是在MB11前臺操作里面卻沒有，所以希望通過增強和BAPI來實現這個字段的賦值

1.首先創建一個附加的結構ZSRESB_APPEND,里面有字段RSPOS，SOBKZ
2.BADI：MB_RES_BAPI_CREATE1對他進行實現，里面代碼如下：
? DATA: LS_EXTENSION LIKE LINE OF IT_EXTENSION_IN.
? DATA: LS_RESB LIKE LINE OF RESB.
? DATA: LS_ZRESB TYPE ZSRESB_APPEND.
? DATA: L_INDEX TYPE SY-TABIX.
? BREAK ZZWANGLP.
? LOOP AT IT_EXTENSION_IN INTO LS_EXTENSION.

??? IF LS_EXTENSION-STRUCTURE = ‘ZSRESB_APPEND’.

????? MOVE LS_EXTENSION-VALUEPART1 TO LS_ZRESB-RSPOS.
????? MOVE LS_EXTENSION-VALUEPART2 TO LS_ZRESB-SOBKZ.

????? READ TABLE RESB INTO LS_RESB INDEX LS_ZRESB-RSPOS.
????? IF SY-SUBRC IS INITIAL.

??????? LS_RESB-SOBKZ = LS_ZRESB-SOBKZ.
??????? MODIFY RESB FROM LS_RESB INDEX LS_ZRESB-RSPOS TRANSPORTING SOBKZ.

????? ENDIF.
??? ENDIF.

? ENDLOOP.
3.在調用BAPI的時候對相應的附加結構賦值：

REPORT? ZWLP_RES.
