Hi,
Use below code for your reference.
data : ref_table_des type ref to cl_abap_structdescr,
          dref type ref to data.
field-symbols : <itab> type standard table,
                        <wtab> type any.
data : mtable type tabname.
LOOP AT i_itf_list INTO wa_list. "wa_list contains list of hr tables.
clear mtable.
mtable = wa_list-tabname.
LOOP AT persno. "persno contains list of personal numbers.
ref_table_des ?= cl_abap_typedescr=>describe_by_name( mtable ).
create data dref type handle ref_table_des.
assign dref->* to <wtab>.
create data dref like standard table of <wtab>.
assign dref->* to <itab>.
***if you want to select multople rows use below select***********
select * from (mtable)
into table <itab>
where pernr = persno-pernr.
********if you want to select single row use below select************
select single * from (mtable)
into <wtab>
where pernr = persno-pernr.
ENDLOOP.
ENDLOOP.
