各位好，
我现在需要通过BAPI BAPI_INTERNALORDER_CREATE来创建内部订单，之前我把AUFK表中的CI_AUFK中做了增强，增加一个自定义字段u201CZZTYPEu201D（4位字符），现在我想在BAPI创建订单的时候把ZZTYPE字段也填充，但测试多次皆发现无法实现，请不吝赐教！代码如下：
form create_io changing c_succeed type flag
c_order_id type aufnr.
data: ls_master_i type bapi2075_7,
ls_master_e type bapi2075_2,
l_order_id type bapi2075_2-order,
lt_rule type standard table of bapi2075_6 with header line initial size 0,
lt_return type standard table of bapiret2 with header line initial size 0,
lt_extension type standard table of bapiparex.
clear c_succeed.
ls_master_i-order_type = '0600'.
ls_master_i-co_area = '1000'.
ls_master_i-comp_code = '1000'.
ls_master_i-bus_area = '1000'.
perform get_extension using lt_extension.
call function 'BAPI_INTERNALORDER_CREATE'
exporting
i_master_data = ls_master_i
importing
e_master_data = ls_master_e
orderid = l_order_id
tables
srules = lt_rule
return = lt_return
extensionin = lt_extension.
if sy-subrc eq 0.
c_succeed = 'X'.
loop at lt_return where type eq 'E'.
c_succeed = ''.
message lt_return-message type lt_return-type.
endloop.
endif.
if c_succeed = 'X'.
commit work.
c_order_id = l_order_id.
else.
rollback work.
endif.
endform.
form get_extension changing ct_extention like gt_extensionin.
data: ls_ci_aufk type standard table of ci_aufk with header line.
data: ls_extension type bapiparex,
ls_bapi_te_aufk type bapi_te_aufk.
clear ct_extention.
clear ls_bapi_te_aufk-orderid.
ls_ci_aufk-zztype = 'tes4'.
move-corresponding ls_ci_aufk to ls_bapi_te_aufk.
move 'BAPI_TE_AUFK' to ls_extension-structure.
move ls_bapi_te_aufk to ls_extension-valuepart1.
append ls_extension to ct_extention.
endform.
