My Source qualifier has empno, sal. Now my mapping is like
SQ(EMPNO)->AGGR->EXP->TARGET
SAL ------------>TARGET ? means only one source
qualifier has 2 columns like empno, sal. connected to same
target as shown in above mapping.Is this mapping valid or
any issues are there if we design like this?

It will invalid the mapping because one column value is
going through aggregator(Active)transformation.so in this
case you can't by pass other column direct to target.
in sql query
select sal,max(empno) from emp;
it is a wrong statement,but if you put like this
selct sal,max(empno) from emp group by sal;
works fine
I think you get the solution
