IF 2 SOURCES ARE RELATIONAL USE SQ T/R
WRITE MANUVAL QUERY
first connect requrired 16+1 attributes to furter t/r or target
select required columns and in where condition write matched condition
if there is no common column go to joiner create sequence in both sources then compare sequence in join vondition
