通过逻辑地址得到物理地址
逻辑地址TCODE: FILE
所对应的物理地址所在的表是PATH
取地址时的代码是：
select single p~pathextern into l_dsn
from path as p join opsystem as o
on p~filesys = o~filesys
where p~pathintern = 'ZMMPP_INFO_GET_OPENPO'
and o~opsys = sy-opsys.
if sy-subrc = 0.
replace: '<FILENAME>' in l_dsn with filename.
else.
message i208(00) with 'Logic path is invalid!'.
stop.
endif.
