Recieved warning on ignoring duplicate entry at table ...no further warnings will be issued for this table.
Solution:
Made the one of the referance link in lookup stage for selecting multiple rows from link and warning has gone.
Query: Is there any impact of data flowed from link after selecting multiple rows from link or it is just removed warning and no impact on data which has been loaded from the link to target.
If you want one row being turned into multiple rows after the lookup, then the setting you used allows that to happen. If you do not want that, then either craft your lookup so it only returns a single row so no warning is thrown, or live with the warning as it throws away all of the 'extra' rows from the lookup.

Shouldn't be all that hard to confirm. As noted, the error tells you that based on your lookup key that it found more than one match in the lookup data. So please, check your 'data set' again.
