1, 前台操作
Tcode:CSKB 输入销售订单号和行项目，点击start order browser展开订单BOM(order BOM).
找到对应的物料，右键display
可以看到链接的文档信息，
2, 例子程序
可以通过函数BAPI_DOCUMENT_SAVEOBJECTLINKS删除order BOM中链接的文档。
逻辑如下：
删除order bom 行项目中链接的文档
1，STPO中读取objectkey，如果要删除订单BOM 头中的链接文档需要从STKO中读取
2，调用BAPI_DOCUMENT_GETOBJECTDOCS取得链接的文档信息
3，调用BAPI_DOCUMENT_SAVEOBJECTLINKS删除文档和订单BOM的链接关系

DATA:g_guidx TYPE stpo-guidx, g_objectkey TYPE bapi_doc_drad-objectkey, git_list TYPE STANDARD TABLE OF bapi_doc_keys, gwa_list TYPE bapi_doc_keys, git_objectlinks TYPE TABLE OF bapi_doc_drad, gwa_objectlinks TYPE bapi_doc_drad, gwa_return TYPE bapiret2. * 测试，所以只取了1条，实际会有多条的情况 SELECT SINGLE stpo~guidx INTO g_guidx FROM stpo INNER JOIN kdst ON stpo~stlnr = kdst~stlnr WHERE stpo~stlty = 'K' AND stpo~idnrk = 'B1-10' "Material Number AND kdst~vbeln = '0690000318' "Sales Order Number AND kdst~vbpos = '200' "Sales order Item AND kdst~werks = '8800' "Plant . g_objectkey = g_guidx. refresh:git_list.

CALL FUNCTION 'BAPI_TRANSACTION_COMMIT' EXPORTING wait = 'X'. ELSE. CALL FUNCTION 'BAPI_TRANSACTION_ROLLBACK'. ENDIF. ENDLOOP.
运行结果，订单BOM行项目上的链接的文档已删除，也就是文档与订单BOM没有链接关系了。
以上。
