Answer / santosh kumar sarangi
1. If source is relational then in SQ you can check the
distinct or in mapping we can use distinct in sorter t/r.
2.if flat file then distinct in sorter t/r.
It will not allow nay duplicate data, so target will get
only distinct data.
Let me know if any thing wrong.
Thanks & regards
