9: 18 a defines the length of the character C (18): L_MATNR_R
10: source of the problem: in the form determine_product_id,
cs_orderadm_i_wrk-product QKB is initialized.
cs_orderadm_i_wrk-product ER1 is not initialized. Is initial
Above the source of the problem, and finally to derive read_single_entry above, global variables found in gs_orderadm_i_adm ER1 no product attribute assignment, global variable QKB in gs_orderadm_i_adm of product properties are assigned values
Two global variable assignment.
1: The last derivation to determine_product_id, ER1 and QKB return different prod_id assignment to global variables.
2: a global variable is assigned a query method Where: positive push, thrust reversers.
Item processing flow:
Three: view the global variable assignment steps:
1: By se38 enter: SAPLCRM_ORDERADM_I_OB
Change item_type enter CRM_ORDERADM_I_MAINTAIN_OW
2：查看全局变量定义的地方：
gs_orderadm_i_wrk在画线处的include中。
四：查找gs_orderadm_i_wrk，要找gs中的值改变的那段代码。
五查询product赋值
1：断点：CRM_ORDERADM_I_PUT_OB
24行： ls_orderadm_i_wrk = is_orderadm_i_wrk.
2：返回到：crm_orderadm_i_create_ow
3：返回到：CRM_ORDERADM_I_MAINTAIN_OW ，返回参数 ：Ev_id=FA163EFEB4D61EE99EDB8761FE6CC040
4：进入：CRM_ORDERADM_I_CHANGE_OW
5：进入：CRM_ORDERADM_I_FILL_OW
6：进入：CRM_ORDERADM_I_MERGE_OW
7：进入: PERFORM determine_product_id
8: 382行代码：cs_orderadm_i_wrk-product = es_product_detail-guid.
9：QKB: 进入以下语句
IF sy-subrc = 0.
* Single hit -> Subsitute other fields
cs_orderadm_i_wrk-product = es_product_detail-guid.
10： 下面的测试案例，QKB有返回值，ER1没有。
六：QKB没有进入
