有感于权限太小（没有se11，12，16），准备研究一下动态内表，准备结合动态内表和动态查询写一个function，达到类试se16的功能。
data tabname type tabname .
data where_clause type string .
data: d_ref type ref to data.
field-symbols: type table.
data: dr_line type ref to data.
field-symbols: type any.
data: i_alv_cat type table of lvc_s_fcat,
ls_alv_cat like line of i_alv_cat.
call function 'LVC_FIELDCATALOG_MERGE'
exporting
i_structure_name = tabname
changing
ct_fieldcat = i_alv_cat.
* internal table build
call method cl_alv_table_create=>create_dynamic_table
exporting
it_fieldcatalog = i_alv_cat
importing
ep_table = d_ref.
assign d_ref->* to .
* Create dynamic work area and assign to FS
create data dr_line like line of .
assign dr_line->* to .
* get data
select * into table
from (tabname)
where (where_clause) .
初步解决一下，还有很多问题，关键是怎么把转换成普通内表。
定义动态结构 方案2：
DATA: lt_ztp009 TYPE TABLE OF ztp009,
ls_ztp009 TYPE ztp009,
dyn_wa TYPE REF TO data.
FIELD-SYMBOLS: TYPE any,
TYPE any.
CREATE DATA dyn_wa TYPE (iv_attribute_structure_name). " 定义动态结构
ASSIGN dyn_wa->* TO .
ASSIGN COMPONENT ls_ztp009-fieldname OF STRUCTURE TO .
CLEAR .
