Hi Kalyan,
  Do it this way: In your code just give the space between (  & (  & lfa1 and also at the end ~lifnr )
select a~lifnr
a~name1
b~bukrs
m~erdat
into table i_lfa1
from ( ( lfa1 as a inner join lfb1 as b on a~lifnr eq b~lifnr ) " maintain a space bwteen ( and field
inner join lfm1 as m on a~lifnr eq m~lifnr ).
or
select a~lifnr
a~name1
b~bukrs
m~erdat
into table i_lfa1
from lfa1 as a inner join lfb1 as b
  on a~lifnr eq b~lifnr
     inner join lfm1 as m
  on a~lifnr eq m~lifnr.
With luck,
Pritam.
